1. Bees have magnetic remanence. ]. L. Gould, ]. L. Kirschrink, and K. S. Deffeyes.
Science, 201: 1026-1028.--The interest of this note to the ornithologists is that it calls
attention to the existence of magnetic structures in the bodies of certain invertebrates.
Apparently in all cases the magnetic matter is FeaOs. Some bees apparently lack these
magnetic structures. When present they are oriented transversely to the axis of the insect.
It remains to be shown that they actually have any significance in orientation and how the
influence, if any, is mediated.--C. H. Blake.
2. Spatial orientation and behavior control. (Prostranstvennaya orientatsiya i uprav-
lenie povedeniem.) V. Ilyichev. 1978. Zhurn, Obshchei Biol., $4(4): 534-546. (In Russian
with English summary.)--Behavioral control as visualized by the author implies an orien-
tated response fully or partly mediated by natural phenomena that the animal recognizes
in its familiar ecological setting as reference points to guide a 1ocomotory response. This
may involve the following factors: a search for and application of ecological particulars
to simulate and incite repellent reactions; a change in the object of attention (formerly it
was an individual, now it is a group of birds); an increase in the number of objects
regulating the response; invoking inherent habits as well as those acquired through learn-
ing. The study of arian behavior as responses to repellent signals is a desirable objective
in studies of control. The repellent impulse spreads from one individual to another, and
each individual modifies the impulse according to its own impression of the situation. The
group generates secondary repellent impulses; each individual receives not just the pri-
mary but the altered signals as well. The group response rests on intermediary individuals
that sense the repellent effect and show their reactions. A combination of effects including
imitated distress calls is recommended. The author suggests that a fear and flight response
might be "trained into the birds' mass behavior." Could it be?--Leon Kelso.

3. Breeding success and mortality of terns at One Tree Island, Great Barrier Reef.
K. Hulsman. 1977. Emu, 77: 49-60.--Although Black-napped (Sterna sumatrana), Roseate
(S. dougallii), Bridled (S. anaethetus), Lesser Crested (S. bengalensis) and Crested (S. bergii)
terns breed on One Tree Island, each species is at the periphery of its range. Cyclones,
floods, and predation by Silver Gulls (Larm' novaehollandiae) were the major causes of
mortality among eggs and chicks. Inter- and intraspecific competition for food was not a
factor in these peripheral populations. In addition to Hulsman's examination of Lack's
food limitation hypothesis, there are abundant data on the behavioral tactics used by
thieving gulls against terns of different sizes. Gulls could and did push Black-napped and
Roseate terns off their nests, a tactic that was not successful against the larger Lesser
Crested and Crested terns. Gulls pilfered eggs and chicks from these larger terns by
patrolling the colonies and swooping on unattended nests. Most interesting is the fact that
several colonies of terns were each guarded by a mated pair of gulls that stole eggs and
chicks from "their" colony and drove away other gulls.--Edward H. Burtt, Jr.

4. Microgeographic prediction of polygyny in the Lark Bunting. Wanda K. Plesz-
czynska. Science, 201: 935-936.--It is shown that the protection of the nest site from solar
radiation is the chief factor in determining whether a male of Calamospiza melanocorys
secures zero, one, or two mates. Artificial shading of an otherwise poor territory increased
the chance of the resident male obtaining a mate. Furthermore, mating success ot males
could be predicted in a previously unstudied area before the arrival of the females.--C.
H. Blake.
5. Measurements and weights of eggs of the Canada Goose, Branta canadensis,
analyzed and compared with those of other species. T. H. Manning. 1978. Can. J. Zool.,
56(4): 676-687.--Besides providing an extensive statistical summary and analysis of the
length, breadth, and indices of shape and volume for 334 eggs (82 clutches) and also of
the weight and density for 125 (30 clutches) of these, Manning presents an extensive
review of similar literature for 31 other species. For the Canada Goose, Manning found
that the variance of egg measurements within a single clutch was approximately equal to
the variance of egg measurements for single eggs compared between clutches. No clear
correlations between any of his measurements and clutch size were found either for this
species or for any in the literature surveyed. The one clear trend was that the last eggs
laid by a Canada Goose have a significantly smaller breadth than earlier laid eggs and
hence were lighter. The one nagging question left by this research and apparently the
literature reviewed in this paper also is, what does any of this variability have to do with
survivorship? Does egg length, breadth, weight, or position in the sequence of laying bear
any relationship to the probability of the egg hatching into a bird that will fledge? Al-
though admittedly this is a much harder question with which to deal, it is only in this
manner that the adaptive significance of the variation reported by Manning and others
can be assessed.--A. John Gatz, Jr.
6. Relationship between nest sites of Common Terns and vegetation on the Eastern
Headland, Toronto Outer Harbour. H. Blokpoel, P.M. Catling, and G. T. Haymes. 1978.
Can. J. Zool., 56(9): 2057-2061.--Common Terns (Sterna hitundo) on this Lake Ontario
shore nest near vegetation and avoid nesting in barren areas.--A. John Gatz, Jr.
7. Egg size, hatching asynchrony, sex, and brood reduction in the Common Grack-
le. H. F. Howe. 1976. Ecology, 57(6): 1195-1207.--Howe compared egg weight, laying
sequence, hatching sequence, nestling growth, and fledgling sex ratio in 16 control and
23 experimental nests of Quiscalus quiscula in southeastern Michigan in 1975. His exper-
imental procedure consisted in removing eggs from the nests as they were laid, tempo-
rarily replacing them with plaster dummies until clutches were complete, and then rein-
troducing complete clutches of real eggs. Nestling sex was determined by laparotomy late
in nest life. His results indicate a trend toward increasing egg weight during the laying
sequence and elimination of hatching asynchrony in experimental clutches. Elimination
of hatching asynchrony changed the normal pattern of brood reduction during the nest-
ling period, as follows. Typically in grackles, young from later, hence larger eggs, are
most likely to starve. In the experimental nests the deaths in the first few days of nestlife
were predominantly from smaller eggs (=those laid first?). Howe does not identify laying
sequence of these eggs. In tests of paired, same-sex siblings, egg size and fledging weight
were positively related. The experimental clutches produced a sex ratio of 1:1, whereas
the control nests produced a ratio favoring females. Because males on the average weigh
more than females at fledging regardless of hatch sequence, Howe suggests that males
are more costly to raise and that brood reduction, which favors females over males, occurs
when food supplies are insufficient to raise a œull brood. He discusses hatch asynchrony
and increased size of later eggs as antagonistic adaptations allowing parent grackles to
raise more young when food supplies unpredictably increase. Fortuitously, food supplies
on one of Howe's study areas did experience a sudden increase and birds at that location
produced very large young. The study is well organized and the discussion of results in
relation to ideas of inclusive fitness is lucid. A sobering difficulty of the study as a field
experiment is that typically no less than 80% of the variance in regression analyses of
subsequent nestling weights on hatch and laying sequence is attributable to factors other
than those controlled by the investigator.--Paul B. Hamel.
8. Effects of addition and removal of nestlings on nestling weight, nestling sur-
vival and female weight loss in the Pied Flycatcher Ficedula hypoleuca (Pallas). C.
kenmo. 1977. Orni Scand., 8(1): 1-8.--Based on two experimental seasons, large broods
(up to nine nestlings) fledged fewer young and survival of those few young was lower
than in small broods. The proportion of surviving nestlings was larger in reduced broods
and smaller in the enlarged ones compared with the unmodified ones. "Due to increased
mortality, enlargement of broods did not result in a higher proportion of fledglings."
Females with large broods lost more weight than females with small broods.--Leon Kelso.
9. Method for determining the incubation stage of Pied Flycatcher Ficedula hy-
poleuca eggs. M. Ojanen and M. Orell. 1978. Orni Fenn., 55(1): 29-31.--The diameter
of the air bubble at the blunt end of the egg may show whether the clutch has been
completed. When newly laid, eggs lack the air bubble and during the first day it does not
exceed 5 mm in diameter. After 4-5 days' incubation it measures 9 mm, and after 9 days
ca. 10 mm. Changes of the color profile in the egg during incubation show how far
incubation has advanced. "This method (or its modification) is considered valid also for
Phoenicurus phoenicurus, Parus major, and Columba palumbus, and fairly good for Sturnus
vulgaris." These data were verified from a collection of about 40 nests of the Pied Fly-
catcher.--Leon Kelso.
10. Development acceleration of sensory and motor mechanisms of nestlings as
factors of systemogeny of some bird species. (Akseleratsiya sensornykh i motornykh
mekhanizmov ptentsov kak faktor sistemogeneza nekotorykh vidov ptits.) S. Khayutin and
L Dmitrieva. 1978. Zhurn. Obshch. Biol., 34(2): 289-296. (In Russian with English sum-
mary.)--This is a behavioral analysis of the cavity nesting Pied Flycatcher (Ficedula hypo-
leuca) and Great Tit (Parus major) whose broods hatch asynchronously from the same
clutch of eggs. With optimum diets the nestling period of the youngest chick was shortened
by 20-25%. Thus the whole brood tends to depart simultaneously. This was attributed to
accelerated development of the youngest chick's sensory and motor components. This was
promoted by increased motor activity, by the steady motivation and contact with older
nestlings, thus "enriching the environment in which their development takes place." The
following factors contribute to synchronized nest departure: 1. A high level of food mo-
tivation throughout the nesting season, with steady rise in motor activity. 2. Permanency
of young in a sensorially enriched state, enhanced by vocalization and movements of older
nestlings. 3. Stabilization by the bulk of elder young before departure. Young hatched
later reach the same bulk and depart omitting the "plateau" stage. 4. Increased intervals
between feedings just after nest departure of older young. The authors suggest that
synchronization of nest departure is an adaptive response determined by mutual accel-
eration of sensory and motor components. Is this a form of socially enriched "affirmative
action?"--Leon Kelso.
11. On lability in evident embryo adaptation of the Common Cuckoo. (O labilnosti
v proyavlenii embrioadaptatsii obyknovennoi kukushki.) E. Leonov. 1978. Biol. Nauki,
1978(5): 53-55. (In Russian.)--The author compares the rate of embryological develop-
ment of Cuculus canorus to that of one of its victims, Serinus canaria, by means of ovoscopy
(candling). Total time of incubation averaged 43 hr less for the Cuckoo embryo than for
the Serin. The egg of the latter was only slightly smaller than that of the Cuckoo, 21 x 16
mm. The Cuckoo embryological development in the first 33 hr equaled that of Serinus in
60 hr, the time discrepancy being 27 hr. The progression of the time discrepancy (Serin
versus Cuckoo) was 60-33 (27); 72-40 (32); 84-47 (37); 108-71 (37); 192-155 (37); 240-
203 (37); 264-215 (49); 288-239 (49); 302-269 (33); 315-272 (43). These results indicate
that the Cuckoo egg may be delayed in the oviduct, leading to shortening of its sojourn
in the nest of the host. Presumably the shortened incubation is adaptive for several rea-
sons: the female's difficulty in finding hosts, concluded reproductive cycles in potential
hosts, necessity of fortuitous host choice, and others. In the course of evolution the Cuckoo
has adapted to nest parasitism, by laying its egg at a more advanced stage of development.
So here we find evident lability of embryo adaptation, and not accelerated development
of the parasitic embryo.--Leon Kelso.
12. Breeding of Antarctic Terns in the Snares Islands, New Zealand. P. Sagar.
1978. Notornis, 25(1): 59-70.--One summer, 1976, at Snares Islands daily records were
kept for 10 nests of Sterna vittata. In two periods, late October and late November, one,
rarely two eggs, were laid. Both adults incubated an average of 24 days. Both parents fed
the chicks which fledged 27-32 days after hatching. Nests were solitary; "slight scrapes in
shallow peat and vegetation." "All identified food proved to be fish." The authors note
that the fledging period is similar to that of the Common Tern (S. hirundo), about 28 days,
"but is significantly longer than that of the Arctic Tern, about 21 days." Overall, Antarctic
Tern clutch size increases with latitude from 1 to 2 eggs, in contrast to the Arctic Tern
(S. paradisaea) which shows a decrease from an average of 2.4 to 1.5 from boreal to high-
arctic 1ocalities.--Leon Kelso.
13. Particulars of the breeding of the Arctic Tern (Sterna paradisaea) on the Baltic,
White, and Barents seas. (Osobennosti razmnozheniya polyarnoi krachki na Baltiiskom,
Belom, i Barentsevom moryakh.) L. Belopolskii, G. Goryainova, N. Milovanova, I. Petrova,
and N. Polonik. 1977. Ornitologiya, 13: 95-99. (In Russian.)--The egg-laying, hatching,
and fledging dates for 810, 83, and 406 young for the above areas (respectively) were
recorded and tabulated as well as graphed in detail. This was a cooperative study carried
out in 1970. The Baltic Sea afforded the best nesting weather and other conditions, the
clutches usually numbered three eggs whereas in the other areas two eggs and frequently
one was the clutch size. Whereas the earliest young appeared on the Baltic, then on the
Barents and lastly on the White seas, the hatching peak of all three areas was in the first
five days of July. The earliest fledging and flight of young on the wing was on the Baltic
Sea, the latest on the White. The greatest span of the nesting period in 1970 was on the
Baltic, the shortest on the White Sea. The greatest overlap of the egg-laying, hatching,
and fledging phases was recorded on the Baltic Sea. Other important, related remarks
and observations are included in this concentrated, cooperative study.--Leon Kelso.
14. Colonies of Anseriformes around Snowy Owl nests on Wrangell Island. (Ko-
1onii guseobraznykh okolo gnezd na o-ve Vrangelya.) E. Syroechkovskii. 1978. Ornitologiya,
13: 211-212. (In Russian.)--That a particular consortium of anatid species cluster their
nests around a nest of Nctea scandiaca has been verified by a number of authors, partic-
ularly Portenko. These groups consist of Snow Geese, Brent Geese, and Common Eiders
(Anser caerulescens, Branta bernicla, and Somateria mollissima, respectively). On Wrangell
Island they are evidently attracted to owl nests for safety from Arctic Foxes (Alopex lagopus).
As a rule such settlements are not stable. They occur in years of owl and lemmihg abun-
dance, and disappear in years of scarcity. The owls allow foxes to approach no closer than
200 to 250 m. The proximity of the anatids to the owl nests varies. Closest usually are the
Brent, 1 to 15 m, beyond that the Snow Geese, and the eiders usually nest on the periphery
of the latter. Observations of 10 owl nests in 1970-1971 found that the owls did not take
the goslings although broods of them frequently passed through the owls' foraging ter-
ritory. On the other hand, nonbreeding owls occasionally swooped at young geese.--Leon
Kelso.
15. Nesting of the Great Spotted Woodpecker (Dendrocopos major L.) in the Len-
ingrad region. (O gnezdovyakh bolshogo pestrogo dyatla (Dendrokopos major L.) v lenin-
gradskoi oblasti.) A Sirotkin. 1978. Biol. Nauki, 1978(1): 65-67. (In Russian).--Contained
are records of 270 nest cavities of the Great Spotted Woodpecker found between 1927
and 1975 in mixed pine-deciduous forest. Of 217 cavities mostly 3-6 m above ground,
176 (79.8%) were in aspen, 15 (6.8%) in pine, 12 (5.4%) in alder, 7 (3.1%) in birch, 3
(1.4%) in spruce, and 1 each in linden, poplar, larch, and a telegraph pole. Nest mea-
surements averaged: depth, 34 cm, width, 12.5 cm, diameter of entrance, 4.9 cm. En-
trances were not directionally oriented, but oriented by the state of decay in the trunk.
The chambers appeared to have been enlarged between hatching and departure of the
young. One cavity was widened from 10 to 11 cm, deepened from 36 to 44 cm, and the
entrance was slightly enlarged, all this between the nestlings' 5th and 23rd day of life. Of
203 cavities inspected from April to June, only 22 (11%) were occupied by Dendrocopos.
The remainder were occupied by alien species, including Starlings (Sturnus vulgaris) and
Pied Flycatchers (Ficedula hypoleuca).--Leon Kelso.

16. The behavior and vocalization of young Turquoise-browed Motmots. S. M.
Smith. 1977. Biotropica, 9(2): 127-130.--The ontogeny of behavior in nine hand-reared
Turquoise-browed Motmots was divided into comfort movements, exploration and feed-
ing, vocalization, play, and displays. Comfort movements (preening, stretching, and
scratching) were first observed when the young fledged from their enclosed nest boxes,
but were probably developed earlier. Bathing appeared a few days after fledging. Dust
bathing took place on the ground in a standard manner. Water bathing behavior was
performed by the birds when they heard the sound of rain on the roof (but could not see
the rain), and then only when they were on a perch, never on the ground. Play included
food manipulation and tail chasing. (No individual ever caught its own tail.) Vocalization
and displays are classified according to the circumstances under which they were first
exhibited and the age at which they first appeared.--Robert C. Beason.
17. Pair-bond and bonding behaviour in three species of grassfinches of the genus
Poephila (Gould). R. Zann. 1977. Emu, 77: 97-106.--Pair-bond and associated behavior
arc described for five subspecies from three species. The paper has several commendable
points: the behavioral patterns arc gi3/4cn descriptive names (e.g., head jerk, head and tail
twist), several excellent linc drawings supplement the behavioral descriptions, and a wealth
of quantitative data is presented.
Unfortunately, the paper also contains a number of serious faults. Definition of the pair
bond is critical to the study, but Zann's definition is neither precise nor operational, hence
his observations may not bc rcplicablc. Statistics arc used freely, perhaps too freely and
certainly with too little explanation. Zann misinterprets the data in Table 2. Hc concludes
that "... in the two subspecies of (Poephila) cincta the females did not attack either sex
preferentially." The table shows that the quoted conclusion accurately depicts the behavior
of P.c. cincta, but that females of P. c. atropyalis attacked males 41 times and females 17
times, a signigicant difference (X 2 = 9.92, df = 1, P < 0.001) based on the Chi-squarc
goodness of fit, assuming 29 attacks to each sex as the expected value. Chi-squarc goodness
of fit appears to bc the test used for making the other comparisons in Table 2. Tables 4
and 5 include the result of a Chi-squarc test for independence, but the purpose of the
analysis is unclear and Zann never refers to the statistical results. Added to the irresponsible
use of statistics is the small number of captive pairs, 3 pairs of Poephila acuticauda hecki,
2 pairs of P. cincta cincta, and 3 pairs of P.c. atropyalis. These pairs wcrc augmented by
wild-caught breeding pairs, but the number of breeding pairs of any one subspecies never
exceeds eight and is five or less for three of the five subspecies. Such small samples could
bc strongly affected by one aberrant pair and the data arc presented as totals for each
subspecies, hence the reader cannot assess the variance between pairs. These problems
render the study an interesting pilot study, but no morc.--Edward H. Burtt, Jr.
18. Observations on the behaviour of Hall's Babbler. R. P. Balda and J. L. Brown.
1977. Emu, 77:111-114.--Hall's Babblers (Pomatostromus halli) live in a stable flock of
from 5 to 15 individuals. The flock maintains an exclusive home range in which it forages
as a cohesive unit and in which the flock has a single nest. Members of the flock roost
communally, share food, allopreen, co-operate in feeding the incubating female and pos-
sibly in protecting her nest. Based on observation of only eight flocks during a single week
this fascinating paper should stimulate more extensive study.--Edward H. Burtt, Jr.
19. Indiscriminate interspecific aggression leading to almost sole occupancy of
space by a single species of bird. D. D. Dow. 1977. Emu, 77:115-121.--The Noisy Miner
(Manorina melanocephala), an Australian honeyeater, lives and forages in dense, often large,
permanent colonies in open woodland. All avian species that enter the colony are attacked
and occasionally killed by colony members. In large colonies that exclude all avian species
Noisy Miners exploit a wider range of feeding zones than in small colonies that are unable
to exclude all other birds. Here is a communal species that is unilaterally and interspe-
cifically territorial, possibly the only such species. How could such a system evolve? Dow
offers several interesting possibilities, but no explanation is entirely satisfactory. We simply
know too little about Noisy Miners. One of the great dangers in seeking an explanation
is to resort to group selection and Dow is perilously close to invoking group selection
several times. Nevertheless Dow's paper is an eloquent introduction to the biology of the
Noisy Miner.--Edward H. Burtt, Jr.
20. An analysis of the song-flight of the Lapwing (Vanellus vanellus L.) with respect
to causation, evolution and adaptations to signal function. T. Dabclstccn. 1978. Behav-
iour, 66: 136-178.--Thc author first describes the particular flight components and sounds
accompanying them, the flights being distinguished by differences in such variables as
wingbeat frequency and angle at which the wings arc held. Hc then analyzes the sequential
structure of song-flights to complete the classification. Next the contextual situations arc
related: song-flight behavior is basically spontaneous, but modified by external context
such as return to territory, presence of male or female conspecifics, presence of prcdators,
time of day, and weather. From these facts Dabclstcen tries to tease apart the "motiva-
tional" balances leading to various parts of song-flight, and then discusses their evolution
as signals carrying different kinds of information. Conceptually the study is classical cthol-
ogy: a good piece of quantitative natural history.--Jack P. Hailman.
21. Early learning and its effect on population structure. Studies of a wild pop-
ulation of Snow Geese. F. Cooke. 1978. Z. Tierpsychol., 46: 344-358.--This is an important
study with quantitative data, and as such calls for close scrutiny of the findings and con-
clusions drawn from them. The Snow Goose (Anser caerulescens) colony studied in northern
Manitoba is of the subspecies A. c. caerulescens, which has a white and bluc color phase.
Other studies suggest that a single gcnc complex with bluc dominance is responsible for
the color, but dominance is incomplete because offspring from mixed pairs show some
white on their bellies.
The first set of results is the morphic composition of pairs in the colony, which is very
stable over the period 1968-1977 (Table 1, p. 348). White-white pairs constitute about 65%,
blue-blue pairs almost 20% of the pairs present, leaving roughly 15% mixed pairs. The
conclusion drawn is that "The assortativc mating in terms of plumage colour is readily
demonstrable," but it is difficult to scc that this follows from the data cited. The reasoning
is that, based on proportions of the morphs present, mixed pairs should consitutc some
35-40% of the colony if mate choice wcrc random. However, the gccsc do not pair on
the colony, but on their wintering grounds where many colonies mix. In order to derive
a random mating prediction, one must know the proportion of morphs present when
mate choice occurs. If birds from the study colony winter in different sites having different
morphic/scxual proportions, then it is impossible to reason about nonrandom mating from
the proportions of colony birds the following summer. The author's conclusion might bc
correct, but it cannot bc drawn from the data presented.
Next, the pairings of birds of known parentage arc analyzed (Table 2, p. 349). There
is a statistically significant tendency for birds to mate with a bird of the color of their
parents in all years analyzed, but as Cooke correctly points out this reveals no cause-effect
relationship. Therefore, hc analyzes the color of the mate of birds from mixed matings
(Table 3) and finds that white birds from mixed matings tend to pair with white birds,
and bluc with blue. This is better evidence, but does not break the birds down by sex,
although it is females that tend to return to the natal colony so wc may assume that most
of the birds in this table arc females. Table 4 treats presumably the same data according
to the color of the mother, and finds no difference in mate choice according to mother's
color. However, the data arc not broken down by the color of the bird itself, so this
analysis hardly helps in teasing apart any interaction of self-color and color of parents.
Table 5 is a (nonspecified) mixture of experimental and field data showing that each sex
(not broken down by color) from like-color parentage tends to choose a mate of the
parental color (also not broken down by color). The conclusion of all this is: "To sum-
marize, field data indicate that parental colour is correlated with mate choice" (p. 350),
to which might be added: so is color of self and sibs. The remainder of the paper is a
discussion and modeling of effects based on the conclusions.
This is a very difficult situation to analyze, but I do not believe the conclusions to be
well founded at any major step in the reasoning. The summary conclusion that "Evidence
is presented that such assortative mating results from pre-pairing experience and that
familial colour, both parent and sibling, affects subsequent mate selection" (p. 356) is
without substance. Birds tend to be paired with mates of their own color, but until the
pairing process on the wintering grounds is analyzed it remains possible that this corre-
lation is due to random mating. Furthermore, if real mate choice by color does occur
(nonrandom or assortative mating), there is no firm evidence to dissociate which factors
it is based on: color of mother, color of father, color of self, color of sibs--or, indeed,
none of these experiential factors at all, but rather the genes of the bird. All these factors
are highly covariant among themselves, and the author's method of analyzing for only
some of them, and then one-by-one, is not adequate to the task he has set. One must
analyze not only for the influence of a particular factor, but also its interaction with all
other factors of potential importance. Apparently sufficient data exist for real analysis
that would help tease apart influences: namely, an analysis of mate's color in birds derived
from mixed parents where the color of the bird, the sex of the bird, the color of each
parent (by sex), and the color of the sibs are all known. I would guess from Table 4 that
this complete information exists, for roughly 50 birds, and careful analysis of these 50
birds might be very revealing.--Jack P. Hailman.
22. Significance of mother and sibling experience for mating preferences in the
Mallard (Anas platyrhynchos). T. Klint. 1978. Z. Tierpsychol., 47: 50-60.--The question
was whether a duckling imprints more strongly on its mother or its siblings as revealed
in later sexual behavior. The same stock of game farm birds was used for normally colored
and white mothers, and their clutches were switched a week before hatching to create
differences in color between mother and siblings (controls reared their own eggs). The
family was kept together for 12 weeks after hatching, all birds individually marked and
then released on the observation pond. Criteria for mate choice were: (a) association,
including the female's inciting of other males; (b) mutual raebraeb-palaver ceremony; and
(c) precopulatory pumping or actual copulation. Sexes were about evenly distributed in
all groups. Birds from homogeneous pigmented families (n = 62) chose pigmented mates
(except for one female), birds from homogeneous white families (n = 11) chose white
mates (except for one male), and birds from mixed families had mixed mate choices as
follows. In normal-mother, white-sib families both males (n = 8) and females (n = 8) di-
vided mate choice equally between morphs; in white-mother, normal-sib families 15 males
chose normal partners and 5 chose white, whereas 16 females chose normal and 5 white.
Normal birds on the pond outnumbered whites by 3 to 1, and the author uses this ratio
to create expected frequencies for Chi-square analysis. More than a third of all birds
mated with an actual sib the first year, and unfortunately these data are not broken down
by sex (Table 4, p. 56). The author concludes the sib-sib matings are not of great impor-
tance in dictating color choices of mates, but I am not convinced. If sib-sib matings are
excluded, then birds from normal-mother, white-sib families mated exclusively with nor-
mal, nonsib birds; that is, all choices of white birds were due to mating with siblings. In
the other heterogeneous family (white mother, pigmented siblings), 18 birds chose pig-
mented, nonsibling mates and 10 chose white mates. These results suggest to me a some-
what greater influence of the mother's color than the sibs' in later mate choice. This is,
in all, a fine study, which also reviews briefly results from similar experiments with other
avian species.--Jack P. Hailman.
23. Mobbing in the Pied Flycatcher. Effect of experiencing a live owl on responses
to a stuffed facsimile. M.D. Schalter. 1978. Z. Tierpsychol., 47: 173-179.--A stuffed owl
(Glaucidium passerinum) was presented on a pole near nests of a dozen pairs of Pied Fly-
catchers (Ficedula hypoleuca), and five pairs showed no reaction. One to two days later a
caged owl (G. perlatum) was placed near these five nests for 5 min, in each case eliciting
strong mobbing reactions. Then one day after that the stuffed owl was again presented,
and in all cases elicited strong reactions, although not as strong as to the live owl. Of
course, the experiment is not absolutely conclusive---each pair of flycatchers had advanced
a few days in the breeding cycle, the obvious controls on the seven pairs of initial re-
sponders were not utilized, the live and stuffed owls were of different species, and so
on--but the phenomenon is probably real and similar behavior has been reported in other
species.--Jack P. Hailman.
24. Comments on the exchangeability of Herring Gull chicks after the first week
of life. (Bemerkungen zur Austauschbarkeit yon K6ken der Silberm6we (Larus argentatus)
nach der ersten Lebenswoche.) D. B. yon Rautenfeld. 1978. Z. Tierpsychol., 47: 180-181.
(In German with English summary.)--Tinbergen had shown in 1936 that Herring Gulls
in a ground nesting colony would not accept a swap of chicks more than four days after
hatching, but Esther Cullen later found that cliff nesting Kittiwakes (Rissa tridactyla) ac-
cepted chcks more than a week after hatching. In a few cursory swaps von Rautenfeld
found that cliff nesting Herring Gulls also accept chicks after a week. The conclusion of
a difference between Herring Gulls nesting in different sites must be established by more
extensive and better controlled experiments, hopefully with some real data on the behav-
ior of the parents, but this study is certainly provocative. It suggests that when young are
tied to the nest site, parents do not develop individual recognition very rapidly, a point
supported by Burtt's recent study on swallows showing that individual recognition takes
place only after the young fledge.--Jack P. Hailman.
25. Observations of the behavior of Sappho sparganura in the highlands of Santa
Barbara, Jujuy, Argentina. (Observaciones sobre la conducta de Sappho $parganura en
el cerro de Santa Barbara, Jujuy, Argentina.) F. Contino. 1975. El Hornero, 11(4): 265-
270. (In Spanish.)--Field observations at 2,000 m showed that individual male Sappho
sparganura (Trochilidae) defended territories within isolated patches of two species of
flowering shrubs (Dunalia branchyacanthia and Acnistus australis). At one site, 35 males
occupied territories within a 0.5-ha clump of vegetation. In addition to all conspecifics,
male S. sparganura attacked the smaller hummingbirds Microstilbon burmeisteri and Leucip-
pus chionogaster, but refrained from attacking larger species. Females established feeding
territories near their nests. Nests, which were constructed primarily of lichens, were sus-
pended from slender roots in recesses in the walls of shady, moist, 1-5-m ravines. Two
white, cylindrical eggs were usually incubated for 19-20 days, and young flew 31-32 days
after hatching. Males did not assist in incubation or care of the young, but in one instance
an adult male approached a newly fledged young, displayed, and touched the fledgling
with his bill until chased away by the female.--Robert B. Waide.

26. Sympatry in woodpeckers of lowland Malayan forest. L. L. Short. 1978. Bio-
tropica, 10(2): 122-133.--The greatest number of sympatric woodpeckers in the world
occurs in Malaya, 13 species from 10 genera. Field and museum observations on ecology
and morphology were used to explain the coexistence of so many species. Size varied from
9 to 430 g. Species that were similar in size used different foraging modes, which were
related to morphological differences. Most species used foraging techniques other than
prolonged woodpecking. Unspecialized species fed mainly on ants and termites that were
on or just beneath the wood surface. The most specialized woodpecking species were
separated by size. The remaining five species were separated by size, foraging technique,
and/or habitat. This study is one of very few competition studies in which morphology is
related to the ecology and feeding behavior of the species involved. It would have been
even more valuable if a detailed comparison of food types had been given.--Robert C.
Beason.
27. Niche shifts in New Hebridean birds. J. M. Diamond and A. G. Marshall. 1977.
Emu, 77: 61-72.--Of the 56 species of birds inhabiting the New Hebrides, 35 shift their
niche or abundance if populations on different islands are compared. Twenty-eight
species shift the niche spatially by expanding or restricting the habitat occupied, by chang-
ing the altitudinal range, or by adjusting the preferred foraging height. Two species show
pronounced dietary shifts and five species retain similar habitat preferences in the New
Hebrides and elsewhere, but show pronounced changes in abundance. If islands are
classified by area or number of resident species, then the "incidence" of a species is that
fraction of islands in a given size or resident species class inhabited by the species. If
incidence is plotted against area or number of resident species on an island smooth curves
(incidence functions) result. Between the New Hebrides and the Bismarcks or Solomons,
13 species show incidence shifts.
Twenty-one New Hebridean species seem not to shift their niche. Some of these
species may occupy such distinctive niches that interspecific competition is unimportant.
Some species may be limited by the physical environment (e.g., nest sites) rather than
competitors. Some species occur only in the presence of their closest competitors, a few
occur too infrequently to be sure of niche shifts, a few will require quantitative studies to
assess possible niche shifts.
Diamond and Marshall's comprehensive survey of New Hebridean birds suggests that
competitors are a more proximate cause of the species' distributional limits than are
adaptations to the physical environment. Are niche shifts merely the result of behavioral
adjustment or is genetic change necessary? The lack of morphological differentiation
among populations on different islands and the recency of colonization on many islands
suggest that colonizing populations may make immediate behavioral adjustments through
interference competition or through testing the rate at which a particular habitat can be
harvested and settling in the most efficient habitat. Later, gene frequencies will shift as
a result of the new selective pressures that result from the behavioral change in the
niche.--Edward H. Burtt, Jr.
28. Pollination by birds of native plants in South Australia. D. D. Paton and H. A.
Ford. 1977. Emu, 77: 73-85.--Honeyeaters (Meliphagidae) frequently visit (80% of all
observed visits) flowers of many species whereas lorikeets (Loriidae) visit flowers frequently
but only Eucalyptus flowers and a few other birds occasionally visit flowers. Honeyeaters
captured in mist nets carried a few to thousands of grains of pollen on the bill (sticky
pollen) and facial feathers (triangular grains lodged between barbules). Observation of
unpollinated flowers that were subsequently visited by birds confirms that honeyeaters
can cross-pollinate flowers. The paper concludes with a speculative discussion of the rel-
ative importance of insects and birds as pollinators and the coevolution of flowers and
birds. One cautionary note, the first table requires close scrutiny because the print is small
and the difference between a capital P, frequent visitor, and a small p, infrequent visitor,
is very hard to see.--Edward H. Burtt, Jr.
29. Trophic relations of birds and some invertebrates in tundra ecosystems. (Trof-
icheskie vzaimoomosheniya ptits i nekotorykh bespoozvonochykh v tundrovykh ekosis-
temakh.) A. Kishchinskii. 1978. Zhurn. Obshch. Biol., 39(2): 212-226. (In Russian with
English summary.)--The total consumption of Dipteran (Tipulidae, Prionocera spp.) lar-
vae by birds on the Yana and Indigirka deltas, lowland tundra totaled 2.5 to 3.0% of a
nesting season biomass. Larval numbers fluctuate during the growth period but daily
consumption varies little. Under this lies the trophic web of polyphagous birds during
maximum abundance of larval growth with seasonal feeding on them by the specialized
bird species and their subsequent migrations. This affords "stability of relations in the
trophic web." The most important effect of the birds is on the more mature larvae, just
before and during pupation. The dominant birds in order of listing in this situation were
Calidris melanotos, C. acuminata, Philomachus pugnax, Limnodromus griseus, Phalaropus lobatus,
P. fulicarius, Gallinago gallinago, G. stenura, Rhodostethia rosea, Calidris alpina, Somateria fisheri,
Pluvialis squatarola, Tringa erythropus, Pluvialis dominica, and Arias formosa. The author theo-
rizes that the polyspecific trophic web resting on Prionocera larvae developed during the
course of evolution as a predator adaptation to seasonal variation of abundance and
availability of yield (with territorial relationships and differential migration of various bird
groups) and also prey adaptation (including unavailability in seasons of low numbers). In
all this trophic web may be regarded as stable and well balanced. Thus, since in the tundra
situation the life cycle of Prionocera covers several years, in some years high mortality of
certain age classes may occur. Mass flights of crane-fly adults and loss of larval populations
at an early stage might occur; then in the next year small larvae might be less available
for birds. In such years the system is "unbalanced." Numbers of shorebirds specialized on
Prionocera diet might be much reduced; they might not nest at all. Such a situation was
seen in Taimyr by Yu. I. Chernov (Ornitologiya, 8: 133-149, 1967). However such situa-
tions are not frequent. It is suggested that the trophic system "shorebird-crane fly, Prion-
ocera" is quite primitive. Possibly it existed before the present tundra, but during its
formation it attained some biological advantages and secured a dominant position. Pre-
sumably this system is more ancient, more evolutionarily "refined" and perfected than,
for example, the trophic chain of "lemming-myophage" in which colossal fluctuations
regularly occur.--Leon Kelso.
30. Test of optimal sampling by foraging Great Tits. J. T. Krebs, A. Kacelnik, and
P. Taylor. 1978. Nature, 275(5675): 27-31.--Great Tits (Parus major) were given two for-
aging patches that differed in food availability, and tested to see how they decide which
patch to exploit. Two models were tested: "immediate maximising" (always forage in patch
with higher expected reward rate), and "two-armed bandit" (explore each patch to acquire
more information about relative quality, before making a choice). Simulation of the latter
model used a Bayesian approach to measure the information available to the bird at each
stage. Results supported the "two-armed bandit" model, with birds sampling both patches
at approximately equal probabilities until a decision is reached, and then sampling nearly
continuously at the patch with the higher payoff. Birds tended to sample in short bouts
before switching patches during the exploration phase. A weak component exists for
"immediate maximising" in their strategy due to a slight tendency to switch patches after
a run of bad luck.--B. Dennis Sustare.
31. Feeding behavior and predator avoidance in heterospecific groups. D. H.
Morse. 1977. BioScience, 27(5): 332-339.--Morse attempts to evaluate the advantages ac-
cruing to individuals in heterospecific feeding assemblages. Although he considers other
taxa as well as birds, the literature on avian flocks contributes the bulk of the data pre-
sented. Theories about the adaptive significance of such groupings invoke either more
efficient foraging or better predator surveillance as the primary advantage for partici-
pants. Morse cites four possible advantages under each category, and then attempts a
general synthesis based on both theory and field data. He suggests that foraging overlap
should decrease when birds join heterospecific flocks that are predator mediated, whereas
in food mediated flocks foraging overlap should increase. He concludes that the primary
advantage for most heterospecific groups is probably better predator detection, whereas
monospecific groups are primarily an evolutionary response to the need for more efficient
energy acquisition. However, there is no reason why members of heterospecific groups
cannot be deriving both benefits simultaneously. This is an excellent review and synthesis
of an interesting and provocative problem.--Elliot J. Tramer.
32. Ecological aspects of the time budget of the American Avocet. F. Gibson. 1978.
Am. Midi. Nat., 99(1): 65-82.--Time budgets were recorded for 36 Avocets (Recurvirostra
americana) in an Oregon marsh. The 422 hr of observation spanned one breeding season;
12 categories of behavior were noted. Maintenance and reproduction comprised 76% and
26% of total time, respectively (5 = 102%?). Feeding time averaged 36%, but varied as
seasonal energy requirements changed. Activity peaked in early morning and afternoon.
Males appeared more aggressive, while females devoted more time to incubation. Oth-
erwise the time budgets and ecological roles of the sexes were similar.--Elliot J. Tramer.

33. A transmitter attachment for blackbirds. M. L. Martin and J. R. Bider. 1978.
J. Wildl. Manage., 42(3): 683-685.--The authors describe a 2.8-g, 2 x 1 x 1-cm trans-
mitter with guitar string antenna. Life expectancy of the mercury battery is 25-45 days.
Martin and Bider give explicit directions for attachment of the device, using a procedure
that overcomes numerous previously encountered problems including effective attach-
ment during molt. No information is given about the strength of the transmission from
the unit. Eight male Red-winged Blackbirds (Agelaius phoeniceus) so tagged were followed
from 5-35 days. The tagged birds resumed normal movements on the first day following
tagging. The method seems a promising way to study movements, particularly local move-
ments, of medium-sized birds for periods up to one month.--Paul B. Hamel.
34. Sheep losses on selected ranches in southern Wyoming. J. R. Tigner and G.
E. Larson. 1977. J. Range Manage., 30: 244-252.--Sheep losses to all causes were assessed
on five ranches during 1973-1975, with about 6,000 ewes and their lambs monitored each
year. Of 4,440 dead sheep and lambs examined, predators killed 1,030 (23%). Of the
1,030, Golden Eagles (Aquila chrysatos) killed 93 (9%). The loss to Golden Eagles per
sheep-year was thus about 0.5%. With the loss to eagles being in the killing of lambs, it
seems probable that, with appropriate research, management practices for averting even
this small loss might be found and used as an alternative to killing the birds.--Paul A.
Stewart.
35. The impact of foraging meadowlarks, Sturnella neglecta, on the degradation of
cattle dung pads. J. R. Anderson and R. W. Merritt. 1977. J. Appl. Ecol., 14: 355-362.--
In searching for undigested barley seeds to be used for food, meadowlarks in California
pastures during the fall and winter tear apart cattle dung pads. After 12-15 months, 90-
100% of the ground surface originally covered by the pads pecked apart by the birds was
covered with newly sprouted vegetation. Without their being pecked apart, the dung pads
inhibited plant growth during 2-3 growing seasons. Although it is in itself a small con-
tribution to man's economic interests, the pecking apart of cattle dung pads in pastures
must be considered when assessing the economic value of the meadowlark. Much oppor-
tunity now exists for this type of imaginative research in economic ornithology.--Paul A.
Stewart.
36. Predation of cossid moth larvae by Yellow-tailed Black Cockatoos causing
losses in plantations of Eucalyptus grandis in north coastal New South Wales. R. S.
McInnis and P. B. Carne. 1978. Aust. Wildl. Res., 5: 101-121.--Wood-boring insect larvae
are eaten by the Yellow-tailed Black Cockatoo (Calyptorhynchusfunereus), the larvae being
extracted from the trunks of Eucalyptus grandis. In extracting the larvae, the birds weaken
the trees so that many of the trunks are later broken by strong winds. Eucalyptus grandis
is extensively used for pulpwood production in the area where this study was made, and
losses of the trees by breakage sometimes amount to 40% of the stand.
From results of this study the authors conclude that tree breakage caused by the
feeding activities of cockatoos might result in a desirable thinning of the stand in tradi-
tional forestry systems and in the regeneration of logged native forests. However, tree
breakage in pulpwood plantations involves a loss that cannot be repaired during the life
of the plantation. Cossid infestation was most severe in plantations experiencing some
form of stress, particularly competition with grasses at an early stage of tree growth. The
recommendation was therefore made that use of old grasslands be avoided in establish-
ment of plantations or that the grass be controlled with selective herbicides and that
fertilizer application be made to accelerate tree growth. Another approach recommended
was to encourage the development of a vigorous understory of woody perennials to dis-
courage foraging activity of the cockatoos.
The study reported in this paper adopts a mostly proper ecological approach to an
insect-bird problem.--Paul A. Stewart.

Puleston, and I. C. T. Nisbet. 1978. Science, 202: 333-335.--The productivity of Osprey
(Pandion haliaetus) nests at Gatdiners Island, Orient Point, and the Connecticut River
estuary fell to a low in the early and mid 1960's and has since returned to the levels
observed in 1938-1942. Exchange of eggs between their area and Maryland, where the
hatching rates were higher, showed that the lower levels were a property of the eggs and
not a consequence of adult activities or human disturbance. Shell thickness was positively
related to hatching rate. Four pesticides and pollutants were studied by analyses of eggs
that failed to hatch: DDE, PCB, dieldrin, and mercury. The number of young produced
per nest is inversely related to the level of the first two but not clearly related to the level
of the last two. However, dieldrin poisoning of eggs and adults was more marked in the
Connecticut River estuary than elsewhere. This is a paper worthy of detailed study.--C.

Mosk. Obshch. Isp. Prirody, biol. div., 83(3): 67-71. (In Russian with English summary.)--
The nesting requirements of the Little Bustard (Otis tetrax) are "highly specialized." The
peculiarities of the steppe are not the sole nor principal requirements for nesting. On
both virgin and ploughed land the Little Bustard avoids monocultures: tall and dense
grassland, closely grazed areas, areas with brief growing periods for its main food plants.
The Little Bustard's survival is considered unlikely unless decisive measures are taken,
including detailed analyses of nesting biotopes, followed by restoration and maintenance
of protected nesting sites in its preferred biotopes.--Leon Kelso.
39. DDE and PCBs in eggs of Norwegian seabirds. N. Fimreite, Bjerk, N. Kveseth,
and E. Brun. 1977. Astarte, 10(1): 15-20.--The wide distribution of these chemicals in the
environment is now well known but we know little of their occurrence in the eggs of
Norwegian seabirds. Concentrations were measured in 203 seabird eggs from 10 localities,
in eggs of Sula bassana, Larus argentatus, Alca torda, Uria aalge, and Rissa tridactyla. The
average concentrations oFDDE on a wet weight basis were 2.05, 1.57, 1.20, 0.80, and 0.37
ppm respectively. Corresponding concentrations for PCB's were 7.71, 8.49, 5.40, 2.19,
and 2.87 ppm. "With respect to biological effects neither DDE nor PCBs are especially
lethal." For PCB's much remains to be explored but it seems clear that the shell thinning
effects of chemicals of this group are minimal.--Leon Kelso.

40. Resting metabolic rates of ratite birds. W. A. Calder and T. J. Dawson. 1978.
Comp. Biochem. Physiol., 60A: 479-481.--Those who have followed the large volume of
publications dealing with avian metabolism over the past few decades may have doubted
that further important contributions could be made. However, this paper demonstrates
the fallacy of this opinion. Metabolic rates of ratire birds (based upon analyses of four
species: three kiwis and the emu) are much lower than is predicted from the previously
generated Ashchoff-Pohl equation (J. Ornithol., 111: 38-47, 1970). This short but inter-
esting paper points out that "despite several decades of metabolic measurements ... we
still do not understand the evolutionary meaning of basal metabolism and how and why
it is set at different levels in different groups of animals."--C. R. Blem.

Zool., 51:140-154.--Mammalogists have extensively investigated the ecological physiology
of the benefits and debits of living in burrows. The present paper appears to be the first
ornithological attempt at similar analyses. Although the authors have little direct evidence
of the drawbacks, they employ an imaginative series of techniques to illustrate the advan-

problem in a comprehensive manner that is enviable.--C. R. Blem.
42. Temperature dynamics of the fertile chicken egg. S. Kaplan, G. L. Kolesari,
and J.P. Bahr. 1978. Am. J. Physiol., 234(5): R183-R187.--Most papers published by
sophisticated physiological journals are not generally useful to a wide range of ornithol-
ogists because of the complexity of technique, the orientation (i.e., not toward the function
of the organism in nature) or because of the tendency to use domestic species. At first
glance, this paper would seem to fall into all three categories. Computer analyses were
used to model heat fluxes in chicken eggs. However, the technique used could be extended
to studies of natural eggs of wild birds and could result in better understanding of in-
cubation. The authors contend that the site occupied by an early embryo cools more
rapidly than it warms. This finding may be useful in interpretation of incubation during
the early phases of nesting.--C. R. Blem.
43. Seasonal acclimatization to temperature in Monk Parakeets. W. W. Weathers
and D. F. Caecamisc. 1978. Oecologia (Berl.), 35: 173-183.--Monk Parakeets were released
in the United States about 15 years ago and have been increasing in numbers and geo-
graphical distribution. This paper deals with aspects of their physiological characteristics.
Fasting levels of metabolism, evaporative water loss, and heat transfer properties were
measured in parakeets maintained during the summer in outdoor aviaries. These data
were compared with previously published information gathered on similar individuals
maintained under winter conditions (Oecologia, Berl., 18: 329-342, 1961). Fasting levels of
daytime metabolism and heat transfer coefficients of summer and winter birds were sim-
ilar but nocturnal levels of metabolism, body temperature, and evaporative water losses
were significantly lower in winter birds than in summer individuals. The authors attempt
to answer the perennially nagging questions concerning whether winter birds in general
really do have a higher basal metabolic rate than do summer birds, and, if so, what is the
functional significance of such elevation in winter. Analysis of all values available in the
literature reveals a trend that in winter the basal rate exceeds the summer one in small
birds but that the converse holds true for larger birds. This issue is clouded by the fact
that smaller birds generally have higher levels of metabolism at any time of the year than
larger birds, as the authors note. No new insights were forthcoming about the functional
significance of increased levels of metabolic rate during winter.--Cynthia Carey.
44. Estimation of effective parabronchial gas volume during intermittent venti-
latory flow: theory and application in the duck. P. Scheid. 1978. Resp. Physiol., 32: 1-
14.--A major problem in the investigation of avian respiration has been that the effective
volume of the parabronchial lung has never been accurately measured. Anatomists using
casts have estimated that the parabronchial lung volume, including the air capillaries,
might occupy only 10% of the total gas volume in the avian respiratory tract. But even
the anatomists agree that these estimates are subject to technical difficulties. A new ap-
proach using physiological, rather than anatomical, techniques has been developed in this
study. The technique employed here involves the general principle that gas volume is a
determinant of gas exchange under nonsteady state conditions (intermittent flow) but is
not a determinant under steady state conditions (continuous flow). Therefore, if gas ex-
change is measured under the two flow conditions, the ratio between the apparent dif-
fusing capacity of the lung under intermittent flow and the true diffusing capacity under
continuous flow can be used to calculate the effective volume of the lung. These mea-
surements on ducks produced an estimate of 93 ml for the average volume of the para-
bronchical lung, exceeding the prediction of 42 ml based on anatomical measurements.
The author concludes that diffusion and convection occurring across the open ends of
the parabronchus probably contributes toward enlarging the physiological gas volume
available for supply of oxygen above that represented by anatomical space.--Cynthia
Carey.
45. The use of the equivalent black-body temperature in the thermal energetics of
small birds. S. A. Mahoney and J. R. King. 1977. J. Thermal Biology, 2:115-120.--One
ultimate goal of physiological ecologists is to predict accurately the metabolic rate of free-
ranging animals in their natural habitat. This paper represents one step toward this goal.
Since some of the factors affecting metabolic rate are characteristics of the animal (insu-
lation, feather characteristics, etc.) and some are environmental factors (wind speed, tem-
perature, radiational properties of the environment, etc.), the model incorporates both
properties of the animal and the environment in one temperature, the equivalent black-
body temperature (Te). The ability of Te to predict metabolic rate of resting White-
crowned Sparrows under laboratory conditions is tested and the predictions match ob-
served metabolic rates within a mean algebraic error of -1.1%. T can also be used to
interpret laboratory experiments in which several environmental factors (ambient tem-
perature, wind speed, solar radiation, etc.) are varied independently. It now remains to
test T under field conditions with some yet undefined reliable means of measuring met-
abolic rates in order to verify the predictions based on Te. This paper is mandatory
reading for those who love equations.--Cynthia Carey.
46. Influence of weathered crude oil on liver enzyme metabolism of testosterone
in gulls. E. Fl. McEwan and P.M. Whitehead. 1978. Can. J. Zool., 56(9): 1922-1923.-
Previous work has shown that a single oral dose of fresh crude oil can induce increased
liver activity of Herring Gull chicks. The present paper is significant because it reports
the effects of weathered crude oil, i.e., oil that has floated in a tank of water for two to
three weeks was used in the experiments. Although the research was short on replicates
and high on variability, it appears that daily oral dosages of 100 or 500 mg of oil for up
to 156 or 134 days induce no change in levels of either testosterone or its polar metabolites
in adult Glaucous-winged Gulls. Levels of nonpolar metabolites did decrease in gulls
receiving the higher dosage of oil, although the authors offer no explanation for this
effect. Surely further replicated research is appropriate in this area because more birds
are apt to contact weathered than fresh crude oil.--A. John Gatz, Jr.

47. Visual pigments and colour vision in a nocturnal bird, Strix aluco (Tawny
Owl). J. K. Bowmaker and G. R. Martin. 1978. Vision Res., 18:1125-1130.--Owl retinas
are about 90% rods, but do contain cone receptors with three types of visual pigments:
21 of 24 cones absorbed maximally at 555 nm and contained a pale yellow oildroplet
filter. Two cones were found with a 503-nm pigment and dark yellow oildroplet. One
cone's pigment had peak absorption at 463 nm and a pale yellow oildroplet. Red oil
droplets also occur in the Tawny Owl's retina but no intact cones could be measured, so
the visual pigment is unknown. The cone equipment is not extensive, but Martin has
shown in a different study that this owl does possess color vision.--Jack P. Hailman.
48. The lung and air-sac system of the Strigidae, 1. M. Kadosaki. 1977. Tori, 26(2-
3): 87-92. (In English with Japanese resume.)--In four species: Asio otus, Otus scops, 0.
bakkamoena, and Strix uralensis, an interclavicular sac occupies a narrow space surrounded
by the truncus brachiocephalicus and t. sternotrachealis. The outer region of this space is
occupied by extensions of the anterior thoracic sacs. Accordingly, the interpectoral, axil-
lary, and subscapular sacs arise from the anterior thoracic sacs. This feature suggests that
the lack of a part of the interclavicular sac is compensated by the extension of the anterior
thoracic sacs, and may be considered characteristic of the Strigidae. Although the position
of the ostium of the A-connection, which joins the interclavicular sac and the lung, is
variable among species, it is yet located adjacent to the lung hilus and the margo acutus in
the four species examined. These details are largely in the terminology of the author's
summary.--Leon Kelso.

development of young Anatidae from egg-laying to fledging is influenced by and corre-
lated with the appearance of thawed ground or open water, in spring, and the freezing
of surface water in the fall. These observations apply to the genera Cygnus, Anser, and
Branta. The longer the growth period, the larger the final size of the individual. Adap-
tations of the arctic forms to the brevity of the polar summer are suggested. In both
Eurasia and North America the larger species of the three genera favor the southern
areas of the continents, whereas the smaller species venture farthest to the north, 78 ø N
lat. or beyond. The springtime arrival of the larger races is earlier than for the smaller
forms. Altogether both geographic range and initiation of nesting operate to favor smaller
size as an adaptation to the short polar summer. This runs contrary to the Bergmann rule
of larger size northward, but in continental Asia such reversals are seen in other bird
families, in the Tetraonidae, for example. Thus, both geographic distribution and start of
nesting of various Anserinae would indicate that smaller size is more adaptive to a short
polar summer.--Leon Kelso.
50. Herbst corpuscles of remiges in two species of gulls. (Teltsa gerbsta makho-
vykh perev dvykh vidov chaek.) T. Borodulina. 1978. Zool. Zhurn., 57(4): 619-622. (In
Russian with English summary.)--More and more evidence has been accumulating on
responsive sensitivity of bird plumage to the aerial environment. The researches of 11
authors in addition to the account of tactile sensory corpuscles associated with the flight
feathers of Larus ridibundus and L. melanocephalus are summarized here. Similar sensory
bodies have been found throughout most of the avian class. Mass accumulations num-
bering from 2 to 29 have been found in tissues adjacent to the calami and follicles of the
distal primaries of both of these gull species. The size of these corpuscles is also excep-
tional, as long as 1,100 t*. Each of the corpuscles, like the neural bundles supplying
them, is surrounded by densely pigmented cells. In general the pronounced development
of these structures corresponds to the energy delivered through these associated remiges
and to the weight supported by them in flight.--Leon Kelso.
51. Telephoto lens system of falconiform eyes. A. W. Snyder and W. H. Miller.
1978. Nature, 275(5676): 127-129.--The visual acuity of falconiform birds, based on
grating detectability, is about twice that of humans, even though birds with an axial eye
length equal to man's have a minimum intercone spacing only slightly less than in the
human retina. The concave portion of the deep nasal fovea in falconiforms may serve as
a negative lens in a telephoto arrangement, producing an effective focal length exceeding
the physical length of the eye. This design may yield increased resolving power beyond
the limitation imposed by optical crosstalk between densely packed cones.--B. Dennis
Sustare.

52. Aztec Emperor Auitzotl and the Great-tailed Grackle. P. D. Haemig. 1978.
Biotropica, 10(1): 11-17.--This interesting paper postulates an explanation for some
of the discontinuous distributions of Central and South American species that also appear
in the Mexican highlands. Prior to European conquest, the Aztecs used many brightly
colored feathers for ornamentation of themselves. To meet the demand, many species
were imported live through trade with, and poaching expeditions to, southern Central
America and northern South America. Records kept by the early Spanish explorers doc-
ument the aviaries and their tropical avifauna, including Quetzals and macaws which do
not occur within several hundred kilometers. The introduction of the Great-tailed Grackle
was told to Sahagfin, an early 16th century friar. The grackle was introduced and liberated
by the Aztec Emperor Auitzotl from the region of Veracruz. The activity of people living
in Central America and western South America and their trafficking of exotic birds to
Mexico must be considered when trying to explain modern distributions.--Robert C. Bea-
son.
55. The Carolina Parakeet in Indiana. D. McKinley. 1976. Indiana Quart., 54(4):
97-107.--Careful scholarship is a pleasure to encounter, though not always easy to read.
The present account is one of a continuing series resulting from McKinley's historical
researches into the biology and history of Conuropsis carolinensis. The author analyzes a
large number of original accounts, reconciling inaccuracies between these data and the
summaries by Butler (Auk, 9: 49-56, 1892; "Birds of Indiana," 1898; Rept. State Geologist,
Indianapolis, 1897:515-1197, 1897) and Ridgway (USNM Bull., 50: pt. 7, 1916). Analyses
are presented in sections following a generally north-south sequence of divisions of the
state. Carolina Parakeets were found virtually throughout the year in the southern part
of the state, especially in the White River watershed and lower Wabash River valley. A
paucity of records along the Ohio River probably reflects a bias in reporting by observers
who, having noted the bird in Ohio or Kentucky, did not mention its presence in Indiana.
The latest authenticated record for the state is apparently 1858. The paper suffers in that
the author provides neither a summary of his findings nor a map indicating the distri-
bution of this extinct species in Indiana. Unfortunately McKinley did not see a proof of
the paper and was unable to correct numerous typographical and other errors in the
paper.--Paul B. Hamel.
54. Observations on the naturalized distribution of the Red-vented Bulbul in the
Pacific, with special reference to the Fiji Islands. D. Watling. 1978. Notornis, 25(2): 109-
117.--Watling discusses the history and distribution of Pycnonotus cafer, which was acci-
dentally introduced at Fiji and several other islands around 1900. Its distribution seems
related to that of the weed species that constitute its principal food.--J. R. Jehl, Jr.
55. Seabirds found dead in New Zealand in 1976. C. R. Veitch. 1978. Notornis,
25(2): 141-148.--Excellent analysis of 5,990 seabird specimens found on New Zealand
beaches in 1976. No major wrecks occurred. Rarities include Puffinus nativitatis (first N.
Z. record) and Procelsterna cerulea.--J. R. Jehl, Jr.
56. New bird records from the Fiji Archipelago. F. Clunie, F. C. Kinsky, and J. A.
F. Jenkins. 1978. Notornis, 25(2): 118-127.--A complete list of taxa recorded subsequent

are presented for the first time.--J. R. Jehl, Jr.
SYSTEMATICS AND PALEONTOLOGY
(See also 56, 74)
57. Presbyornis and the evolution of ducks and flamingos. A. Feduccia. 1978.
Amer. Sci., 66: 298-304.--The author reviews the terrain and formation in which signif-
icant skeletal remains (especially the skull) of Presbyornis pervetus have been found. The
species is related to a shorebird stock from which descend the flamingos and in another
line via Presbyornis, the Anseriformes. To the reviewer the reconstruction of Presbyornis is
reminiscent of the Magpie Goose (Anseranas semipalmata). Note that in Fig. 4, the labels
should be moved 1 cm to the right and, in addition that for the postorbital process should
be lowered 0.5 cm.--C. H. Blake.
58. The identity of the fossil ducks described from Australia by C. W. DeVis. S.
L. Olson. 1977. Emu, 77: 127-131.--Olson has reexamined fossil material from which
DeVis identified nine species of extinct ducks. No valid extinct species were found. The
material represents five species, four ducks, and a pigeon, all alive today. Each of the five
species is now confirmed as having lived in Australia since the late Pliocene or early
Pleistocene, not an unexpected result.--Edward H. Burtt, Jr.
59. Notes on subfossil Anatidae from New Zealand, including a new species of
Pink-eared Duck Malacorhynchus. S. L. Olson. 1977. œmu, 77: 132-135.--In a brief pot-
pourri of paleornithology Olson identifies a new, larger species of Pink-eared Duck (Ma-
lacorhynchus scarletti) from subfossil deposits at Pyramid Valley, South Island, N. Z. He
recommends that the name Biziura delautouri Forbes 1892 be retained for the subfossil
specimens of Biziura from New Zealand and he identifies a right humerus attributed to
Mergus australis as coming from a coot (Fulica sp.). The evidence is detailed and con-
vincing.--Edward H. Burtt, Jr.
60. Banded Dotterel at the Auckland Islands; description of a new subspecies. R.
A. Falla. 1978. Notornis, 25(2): 101-108.--Charadrius bicinctus exilis, a well-marked resident
form from the Auckland Islands is described as new, with notes on its biology and ecology.
The total population is very low, perhaps less than 100 individuals.--J. R. Jehl, Jr.
61. Plio-Pleistocene bird remains from the Carpathian Basin III. Strigiformes,
Falconiformes, Caprimulgiformes, Apodiformes. D. Janossy. 1977. Aquila, 84: 9-36.--A
lengthy, detailed catalogue of fossil bones and bone fragments from the Carpathian Basin
leads to the following conclusions:
1. The divergence of the two European forms, Strix aluco and S. uralensis, may begin
with the Middle Pleistocene form (S. intermedia).
2. Traces of a large owl, the size of the present Eagle Owl (Bubo bubo), are known
from the beginning of the Neogene until recent times.
3. A representative of the Hawk Owl (Surnia ulula) was present in the Lower Pleis-
tocene in the southern regions, whereas the modern form of the Hawk Owl appears only
in the northern regions.
4. The ancestor of the Little Owl (Athene noctua) was present only in the northern
region in Lower Pleistocene times, and survived the Middle and Upper Pleistocene in the
southern region.
5. The remains of nightjars (Caprimulgiformes), swifts (Apodiformes), and diurnal
birds of prey are considered sporadic finds.
The paper, although written in English, is grammatically difficult to follow. The
occasional tables and figures offer the reader little help in interpreting the text. The
introduction, like the rest of the paper, deals with the orders Strigiformes, Caprimulgi-
formes, Apodiformes, and Falconiformes, but there the resemblance ends. The intro-
duction discusses the evolutionary relationships among the orders whereas the paper is
a cataloguing of fossil bone fragments without comparison of any type. Taken as a cata-
logue and description of avian fossils, the article is a valuable reference.--Sharon M.
Minnich.
EVOLUTION AND GENETICS

62. Reunion Harrier (Circus aeruginosus maillardi) on Reunion Island. (Lc Busard
de Maillard (C. a.m. ) de L'Ile de la Reunion.) M. Clouet. 1978. L'Oiseau et R. F. 0., 48(2):
95-106. (In French with English summary.)--Unlike other subspecies of C. aeruginosus
which inhabit forest edge or grassland, C. a. maillardi is a bird of the forest. Clouet presents
data compiled during approximately a year of observing in 1975-1976. Seven nests were
observed the first year, and two pairs were also studied in 1976. Clutch size is 2-3 on
Reunion compared with 3-5 elsewhere. This is interpreted as an adaptation to island
existence, as is the relatively small size of this subspecies. Measurements of 14 specimens,
including three immatures, indicate that sexual size dimorphism in C. a. maillardi may be
greater than in the Madagascan subspecies C. a. macrosceles. This harrier is the only Re-
union raptor; Clouet interprets the greater size dimorphism as a character release in the
absence of competition. Other observations on the biology and life history of this inter-
esting species are given.--Paul B. Hamel.
63. Recent evolution of Zosterops lateralis on Norfolk Island, Australia. P. R.
Grant. 1978. Can. J. Zool., 56: 1624-1626.--A cautionary tale with enough information
to tease, but not satisfy, our curiosity. Grant returns to the Norfolk Island population of
Z. lateralis founded in 1904, and sampled in 1912-1913 and later in 1926. Specimens from
the two collections illustrated a narrowing bill width in Z. lateralis, which indicated diver-
gence away from its established congener Z. tenuirostris. A good example of character
displacement? Alas, no, for later collections (1968-1969) show that the evolutionary trend
had reversed in Z. lateralis, with bill width increasing to the point where it was indistin-
guishable from the original 1912-1913 sample. After ruling out a number of biologically
uninteresting explanations for the reversal, Grant ruled out hybridization. He concludes
that the pattern resulted from "drift" or selection in a temporally varying environment
(i.e., changed food supplies). With obvious frustration, he notes that there is no way to
distinguish between alternatives with the little information available. He suggests that such
frustration and loss of opportunity should be guarded against by more careful study of
populations founded within memory.--William M. Shields.
64. Biochemical homeostasis of the heterozygote at the lysozyme locus in the Jap-
anese Quail. G. Lucotte and M. Kaminski. 1978. Biochem. Syst. Ecol., 6: 145-147.--Here
is a frustrating and puzzling electrophoretic investigation of a polymorphic lysozyme pro-
tein in the quail's egg-white. The authors report a Hardy-Weinberg equilibrium of the
genotypes of the two alleles observed in three quail "populations." They neglect to inform
us what a "population" is, natural or laboratory. Equally frustrating and even more puz-
zling is their discussion of the biochemical versatility of the heterozygote, which displays
an intermediate pH optimum, which they view as an "advantage of the heterozygote
phenotype." Their rationale for this view is elegant and follows traditional thinking. Yet
they reported a Hardy-Weinberg equilibrium, which more often leads to a conclusion of
little selective difference between phenotypes. Perhaps the confusion would have disap-
peared had the authors published in their native language?- William M. Shields.
65. Response to bidirectional and reverse selection for mating behavior in Jap-
anese Quail Coturnix coturnixjaponica. D. L. Cunningham and P. B. Siegel. 1978. Behav.
Genet., 8: 387-397.--This is a baseline study of the genetics of mating behavior of what
is rapidly becoming the avian equivalent of Drosophila or the laboratory mouse in exper-
imental genetics. Male selection was effective in increasing and decreasing the number of
successfully completed matings in replicate sublines, indicating significant genetic (addi-
tive) variance for mating frequency. Reversed selection was also effective in later gener-
ations indicating that the selective regime had not depleted all the variance. The most
interesting point raised was a positive phenotypic correlation between relative aggressive-
ness and mating frequency. The authors attribute this selection of correlated aggressive-
ness to the body-size dimorphism in the quail, with smaller males needing aggressiveness
as a component of successful mating, since there is no elaborate courtship.--William M.
Shields.
FOOD AND FEEDING
(See also 26, 29, 30, 34, 35)
66. Feeding behavior and food habitats of the Boat-billed Heron (Cochlearius coch-
leaHus). J. O. Biderman and R. W. Dickerson. 1978. Biotropica, 10(1): 33-37.-The au-
thors used a night vision device to study the nocturnal feeding patterns of this heron.
They found no differences in feeding techniques or types of prey taken between the Boat-
billed and other herons living in the same area. They conclude that the specialized bill is
not an adaptation to a novel feeding technique or novel food types, but probably for
display purposes.--Robert C. Beason.
67. Toheroa predation by Black-backed Gulls on Darganville Beach, North Auck-
land, New Zealand. P.M. Brunton. 1978. Notorn, 25(2): 128-140.Larus bulleri is an
important predator on beach clams (Paphies ventricosa), which are of commercial impor-
tance in New Zealand. The ecology of the clam and the feeding habits of the gulls are
discussed. Gulls may take up to 20 clams per day, and the local impact of this predation
can be very high.--J. R. Jehl, Jr.
68. Food of the Long-eared Owl Asio otus in Sweden. H. Kallander. 1977. Ornis
Fenn., 34(2): 79-84.--Thc availability principle of both food for the bird and of the bird
for human observation is operative in this study. Information on the diet of Asio otus is
available now from such diverse sources as date palm groves in Iraq and timberline areas
in Norway. About 14,000 prey items from an unspecified number of pellets collected in
southern Sweden wcrc analyzed. "The staple food of the Long-eared Owl in Sweden is
Microtus agrestis, and Apodemus spp." "It seems safe to conclude that it relies heavily on
voles and mice, especially Microtus, and that its food niche is fairly restricted, at least
compared with that of the Tawny Owl, Strix aluco." There is some evidence that abundance
of Microtus largely determines the breeding density of this owl but the question of no-
madism in this species is still undctcrmincd.--Lcon Kelso.
69. Stored nuts, 1/2astanopsis cuspidata, as a food resource of nestling Varied Tits,
Parus varius. H. Higuchi. 1977. Tori, 26(2-3): 9-12. (In English.)-This island population
stores nuts not only as a principal winter food but to feed broods through fledging. Such
a habit is unknown for the mainland population and for other Parus spp. except P. cinctus.
Nuts arc held pointed end forward. Forced into a niche "the obtuse end is knocked on
by the bill to push it in deep, and finally a chip of wood or a clod of earth is stuffed into
the stored place." Nuts wcrc inserted separately or by two's rarely. Storage use persists
through December to May. "Sometimes only part of a nut is eaten and then restored in
a different placc."--Lcon Kelso.
SONGS AND VOCALIZATIONS
(See also 2, 20, 74)
70. Structure of the vocalizations of a speech-imitating African Grey Parrot.
(Struktur der Lauffiusserungen eines Sprache imitierenden Graupapageis (Psittacus eritha-
cus L.).) N. Rauch. 1978. Behaviour, 66: 56-105. (In German with English summary.)--
The 15-year-old bird named Jako learned the Swiss dialect of German from its owners,
and Rauch has made an exhaustive and detailed study of its taped vocalizations. Sounds
were classified into about 100 types of "behavioral elements" and a detailed temporal
analysis made to reveal constants and variables in vocalization structure. Many structural
constancies were discovered, but the actual choice of a phrase-type (element or sequence
of a repeated element) and the duration of a given vocal pattern were variable. Changes
in vocalization parameters were also found over a 2.5-month period. An invaluable study
for those interested in talking birds.--Jack P. Hailman.
71. Species-typical and individually distinctive acoustic features of crow calls of
the Red Jungle Fowl. D. B. Miller. 1978. Z. Tierpsychol., 47: 182-193.--The highlights of
this analysis of recorded vocalizations by captive, free-ranging Red Jungle Fowl (Gallus
gallus) are (1) the constancy of features in crowing by a given individual, (2) the multiple
differences among individuals, and (3) the similarity to crows of the domestic fowl. Miller
points out that vocalizations of the other three species of Gallus are much less similar to
those of domestic fowl, reinforcing the view of monophyletic origin of the latter from Red
Jungle Fowl. Darwin proposed this derivation but poultry geneticists keep suggesting
hybrid origins for domestic fowl. In fact, I am continually puzzled by all the proposals of
hybrid derivation of domestic animals (e.g., the quite mistaken notion that the jackal as
well as the wolf is ancestral to the dog, proposed hybrid origins of the ring dove, domestic
cat, and so on). It does seem possible that the Alpaca originated by breeding the domestic
Llama back to the ancestral Guanaco (Lama guanicoe), but that is not a hybrid between
two natural species. I suspect that theories of hybrid origin in fowl, ring doves, and other
domestic forms come from generalizing botanical origins; however, wild plants are known
to speciate by hybridization, A simple truism is in order: animals are not plants.--Jack P.
Hailman.
72. On rare and little known birds of Bikin River Basin. (0 redkikh i maloizuch-
enykh ptitsakh basselna Reki Bikin.) Yu. B. Pukinskii. 1978. Priroda, 1978(1): 56-76. (In
RussianO--An illustrated popularized account portrays a niche along a river of the Ussuri,
with its general environment of mixed conifer-deciduous timber. There are 22 sharp
black-and-white photographs detailing 10 species. The special concern of the author is
for the owls: Ketupa blakistoni, Ninox scutulata, and Otus sunia. Their duet calling, or an-
tiphonal vocalization is detailed in special accounts. Further search for actual occurrences
in nature of vocal antiphony or duetting is recommended by this author. The author
"taped" and photographed vocal performances at length. In this locality such duetting
was first recorded for the East Asian Fish Owl (Ketupa blakistoni) which is perhaps the
largest as well as heaviest of all owl species.--Leon Kelso.
73. The sound repertoire of the Great Grey Owl, Strix nebulosa. (Lappuglans Strix
nebulosa laten.) V. Berrgren and J. Wahlstedt. 1977. Var Fagelvarld, 36(3-4): 243-249. (In
Swedish with English summary.)--Various calls of Strix nebulosa were recorded during
1972-1974 in Sweden. The male started calling at sunset and continued until sunrise or
later. No daytime calling was reported. Calling was recorded in autumn and winter 1973-
1974, also through April and May. The female called when the male delivered food, a
call similar to that of the nestlings and juveniles. It was also uttered to the male as an
invitation to approach for mating.--Leon Kelso.
74. Acoustic behavior of the Twite, Acanthis flavirostris (L) (Passeres, Fringillidae)
and taxonomic status of its disjunct geographic forms. (Akusticheskoe povedenie gornoi
chechetki i taksonomicheskii status ee geograficheski razobshennykh form.) M. Zablot-
skaya. 1978. Zool. Zhurn., 57(1): 105-114. (In Russian with English summary.)--The phys-
ical and functional vocal qualities have been analyzed bioacoustically by sonograms for A.
f. montanella for frequency spectrum, energy distribution of frequencies, patterns of fre-
quency modulation, duration, and "temporal structures." The adult repertoire included
12 calls and 3 types of songs: random, normal, and courtship. A comparison of function-
ally effective acoustic signals in .4. f. flavirostr, .4. f. pipilans, and .4. f. montanella shows
the existence of vocal differences in Western European and Central Asian forms. A def-
inite divergence occurs between geographic races that may require a taxonomic revision
of these forms since each appears to deserve species rank.--Leon Kelso.
MISCELLANEOUS
75. The letters of John S. Cairns to William Brewster, 1887-1895. M. B. Simpson,
Jr. (Ed.) 1978. North Carolina Hist. Rev., 55: 306-338.--John Simpson Cairns (1862-1895)
came to Buncombe County, N. C., as a boy. Early he became interested in the fauna of
the neighboring mountains and published a list of the county's birds in 1887. Evidently
this led to a letter from Brewster and the subsequent correspondence of which 28 sur-
viving letters are published here with extensive notes and illustrations of people and
places. Cairns was a keen observer. He was aware of the distinctness of the Carolina Junco
and Cairns' Warbler (see A. O. U. Check-list, ed. of 1931). He sent Brewster a considerable
number of skins, nests, and eggs. Cairns foresaw the changes likely to occur when the
mountains could be exploited and made this clear to his friend, Zebulon Weaver, 10 years
his junior, who, as a member of Congress introduced and insured the passage of the act
establishing the Great Smoky Mountains National Park. Cairns was killed by the accidental
discharge of his own gun. The man who led the search for him was Thomas D. Wilson,
who, in 1857, had found the body of Elisha Mitchell.--Charles H. Blake.
76. Work Output of "Zoologicheskii Zhurnal" in 1974-1976. The Editors. 1977.
Zool. Zhurn., 56(5): 806-807.--In 1974, 1975, and 1976 the Zoologicheskii Zhurnal pub-
lished: leading papers (per years respectively)--170, 153, and 165; brief notes--131, 102,
and 107; papers in the section "Methods of zoological research"--18, 14, and 10; other
accounts--36, 27, and 39. Since 1976 the journal has started to publish accounts of de-
fended and approved candidate and doctoral dissertations in zoology. As before, the
board desires that papers published in Zoologicheskii Zhurnal amply protray the status of
zoological research in our nation. In each number are included papers presenting work
in the various fields of zoology, and pertaining to animals of the various taxonomic groups.
As a whole the relative number of publications for various fields of zoology has fluctuated
but little. Most numerous are taxonomic papers (197490, 1975--86, 1976--101); in
second place are papers on ecology (respective to years: 78, 54, and 65); third, papers on
ecological physiology (39, 32, and 20). Less varied are those relative to various taxonomic
groups. Most numerous were the publications on insects (197484, 1975--72, 1976--
73), somewhat fewer--mammals (by years: 54, 42, and 48); birds (24, 42, and 21); Crus-
tacea (26, 26, and 25); flatworms and roundworms (21, 19, and 28); Arachnida (19, 18,
and 20); Mollusca (17, 13, and 9); amphibians and reptiles (18, 12, and 13); and fishes
(6, 17, and 4).
As in past years, most papers published in the journal were by authors from Moscow
(1974106, 1975--106, 1976--115), and Leningrad (respectively: 62, 57, and 52). Papers
by authors working neither in Moscow nor in Leningrad, were published: 1974155,
1975--106, 1976--134.
In 1974, the average time from date of receipt of papers to publication was 12 months,
in 1975--14, in 1976--16. The basic cause of time increase was authors' desire to avoid
at all events the shortening of papers. Notwithstanding all efforts of the editors occasion-
ally papers are published whose length exceeds the advised rules for authors.
In consequence (of the increasing length of papers) the number of papers making
up an issue is minimized. While in 1974 there was an average of 29.7 papers per issue,
yet in 1975--only 24.7; in 1976 the situation improved somewhat (26.7 papers per num-
ber) but at present the board's portfolio is overloaded. Now the board accepts extra length
only in cases where the paper is reserved for the author and the excess previously arranged
for. All other papers whose length exceeds the regulation limit of "Rules for authors" are
not considered and are returned to the authors.
In planning each number of the journal the board desires to include primarily papers
that are of interest to a broad range of zoologists. The time from the date of receipt of
such papers to their publication is definitely less than the average. Nevertheless it must
be said that the great majority of papers received by the board of Zoologicheskii Zhurnal
and published in its pages are on particular topics, primarily description of new species.
In no measure minimizing this genre of work, the board observes that in some cases the
authors are in excessive haste for publication, not using adequately the material at their
disposal. Often descriptions are not adequately detailed for a distinctive diagnosis. The
board asks of authors close attention, and, as a favor, to familiarize themselves with "Rules
for authors," and with recommendations for drawing descriptions, published in no. 10 of
1975.
The board asks that reviewers attend more strictly to evaluation of papers containing
descriptions of new species, not only to mark authors' errors, but also to indicate whether
or not it is desirable to postpone publication until the author makes comparison of the
new species with other species of the genus.
The board expresses sincere thanks to those referees who carefully and promptly
scrutinize the papers submitted to them for review. We must note, however, that some
referees hold papers extremely long, or make superficial readings not affording judgment
of the merits and faults of the work. The board asks that referees in those cases when
they do not expect to render judgment in the next three months return the paper to the
board.
The essential fault of Zoologicheskii Zhurnal continues to be its less than effective
representation of the life in zoological establishments of the nation. Thus, accounts of
conferences or congresses are published a year after the event itself. The board takes
pains to hasten publication of news items; however, favorable results will be obtained only
if authors of reports present them to the board immediately after the conclusion of the
conference or congress whose proceedings constitute these reports.
Collaboration of authors, referees, and editorial boards makes it possible to promptly
publish papers received, and helps make Zoologicheskii Zhurnal of interest to the broadest
spectrum of zoology readers.--Leon Kelso.

Copenhagen. 56 p. text (seen) and cassette, 24 color slides, set of exercises, and teachers'
notes (not seen). (No price given).--The Coot and the Moorhen is one of a series of mono-
graphs intended "to give a picture of the way in which animals live. The books are not
merely intended to give a mass of detailed information about what we know about each
individual species. It is just as important to explain why the animals live and behave the
way they do." The stated purpose is admirably and delightfully fulfilled in a booklet that
brims with facts and excitement. The writing is crisp and concise, a tribute to the author
and to the translator. The excellent photographs complement the text well, but the pen-
and-ink drawings are outstanding. Drawings are often in series to illustrate a complete
behavioral pattern, for example diving, running, or the motion of the coot's toes during
the power and recovery strokes of swimming. Drawings illustrate variations in behavior,
for example the seasonal change in grazing behavior as the reeds grow. Far more could
be said in praise of the book's illustrations, suffice it to say that they alone are worth the
book's price.
Occasionally the text lapses into teleology and functional interpretation is excessive
in places. The distribution maps lack legends, which renders them almost uninterpretable,
and a map of seasonal changes in breeding territories is unintelligible despite a clear
legend. However, these are minor objections to an otherwise informative little book.-

78. Roberts' Birds of South Africa. G. R. McLachlin and R. Liversidge. 1978. The
Trustees of the John Voelcker Bird Book Fund, Cape Town, South Africa. 660 p.--With the
caveat that my experience with ornithological field guides encompasses only the standard
North American guides plus the William's guides to East African birds, and that I was
unable to field test this latest (4th ed.) of Roberts' Birds of South Africa, I give it a very high
mark. Of the 72 color plates by Norman C. K. Lighton and Kenneth Newman, 31 are
new. All seem accurate; all of the plates are beautiful. The plates of flying falcons and
hawks, buzzards, kites, and harriers come to mind as especially lovely. Each bird species
is assigned a number which appears next to the drawing of the bird. The plates are
described on the facing page, where each bird painting is identified by number, scientific
name, common English and Africaans names, and sex and age class where appropriate.
The text copy for each species is easily found in nearby pages by reference to the species
number, its binomial, or common names. Native names in a variety of local dialects are
also included. The plate number that contains the drawing of the described species is
clearly indicated in the text. Species accounts are organized into sections on identification,
distribution, habits, food, voice, and breeding. Marginalia include range maps, line draw-
ings of curious aspects of species morphology and of subspecific morphological differ-
ences. Each family of South African birds is also described in the text. Introductory
sections include nomenclature and classification, regions of South Africa, a few historical
notes, along with statements on field equipment, field identification, and descriptive or-
nithological terms. I believe that this field guide should be easily and satisfactorily used
by the neophyte as well as the seasoned birder and the professional ornithologist.--Patricia
A. Gowaty.
79. The English Sparrow in the American Landscape: A Paradox in Nineteenth
Century Wildlife Conservation. R. Doughty. 1978. Research Paper 19. School of Geog-
raphy, University of Oxford. 36 p.--This short research paper on one of North America's
most successful avian immigrants, the English Sparrow or House Sparrow (Passer domes-
ticus) is an amusing, essentially sociological account of changes in human attitudes towards
introduced species. The historical background of attitude change towards P. domesticus
from active nurturance of the "feisty little foreigners" (introduced by Nicolas Pike in 1851
and successors including Eugene Schiffelin who worked to introduce all of the birds
mentioned in Shakespeare into the United States) to eradication programs of the "hun-
like sparrows" is paralleled by the biological background of rapid range expansion, eco-
logical release, and successful interspecific competition of these birds. The biological fac-
tors as such are not analyzed. This monograph will be useful in undergraduate courses
on management philosophy or where need exists for an illustrative example of the com-
plexities of wildlife management in relation to the vagaries of human value systems.-

80. Birdhouses. (Nichoirs d'oiseaux). R. Cayouette. 1978. Charlesbourg, Que., Soc.
Zool. de Quebec. 36 p. $4.00. (In French.)--M. Cayouette has prepared an attractive pub-
lication dealing with nestboxes, their construction, and briefly describing the biology of
20 species of Quebec birds that use them. Written in popular form the book will find its
widest use among birdwatchers. Land managers, park personnel, and other professionals
will profit from the compendium of specifications for nestboxes for species ranging in size
from chickadees to Wood Ducks, (Aix sponsa) and Common Goldeneyes (Bucephala clan-
gula).
The book is introduced by a discussion of the rationale for aiding hole-nesting species
which are often faced with a paucity of nest sites in an environment dominated by human
activities. Control of pest insects is given a more prominent place as a reason than it
probably deserves. Construction, materials, predator and parasite control around nest-
boxes, and provision of suitable nesting material for hole-nesting species are adequately
treated. Hole-nesters are assigned to one of three groups depending on the frequency of
their use of birdhouses. Within groups the species are listed and treated in an order which
this reviewer has not been able to figure out.
Species accounts feature a watercolor illustration by Jean-Luc Grondin; a capsule
noting such features of the bird's biology as clutch size, incubation time, length of nestling
period, food, range, and migration dates in Quebec; a narrative describing the bird's
habitat, use of nestboxes, and other interesting details. The account of the Cliff Swallow
(Petrochelidon pyrrhonota) for example, gives sound advice for providing suitable nesting
material for the species. Often additional line drawings by M. Grondin illustrate a partic-
ular feature made in the text. Most memorable of these is the depiction of Tree Swallows
(Iridoprocne bicolor) routing a cat on p. 13. The watercolor paintings are painstakingly
detailed, although some of the birds, such as the American Robin (Turdus migratorius) on
p. 24, do not appear lifelike. Nevertheless, the overall effect of this little book is a most
pleasing one, and worth the price. C'est dommage que cette brochure est crite seulement
en franais.--Paul B. Hamel.
81. Water Birds of California. H. L. Cogswell. 1977. Univ. Calif. Nature Guides no.
40, 399 p. Illustrations by Gene M. Christman. $5.75, paperback.--This is a comprehen-
sive review of current information on the distribution and biology of western water birds,
with emphasis on California. Although not intended strictly as a field guide, it provides
sufficient information to allow most species to be distinguished by the layman. It is in-
tended for a broad audience and includes a wealth of interesting information, much
derived from the author's extensive experience, that will help interest the educated layman
in birds as well as in problems of conservation.
A well thought out introduction includes material on a wide variety of topics including
general avian biology and behavior, identification, watching birds, keeping records, de-
veloping research projects, banding, and photography. Conservation is stressed, especially
the importance of habitat restoration. Included are balanced remarks on hunting and
scientific collecting, which are especially appropriate in these days of almost thoughtless
protectionism. All of these topics are treated succinctly but never superficially.
The bulk of the book provides a detailed description of each species, data on iden-
tification, habits, nesting range, and a current synopsis of status and distribution in Cal-
ifornia that is not available elsewhere. The text is accurate, although a few statements are
debatable. For example, all (not "most") confirmed skua records in California refer to the
South Polar form. The idea that skuas look like buteos, repeated here, is an impression
I have never received. Insufficient distinction is made between the Yellow-footed (livens)
and other races of Western Gull (Larus occidentalis) even though its biology, plumages, and
distribution are markedly different. Cogswell alleges that the Thayer's Gull (Larus thayeri)
is suspected of migrating around the coast of Alaska; I cannot recall the origin of that
suggestion, and the bulk of the evidence suggests otherwise.
The book is enlivened by many sketches of Gene Christman and includes 12 color
plates. Each of the major water bird families is represented by one or more of the com-
moner or more conspicuous species that will be encountered by the beginners. For this
reason, the inclusion of the Harlequin Duck (Histrionicus histrionicus) is puzzling.
About one quarter of the book is devoted to appendices. One provides information
on organizations with interest in California ornithology. The major appendix, comprising
nearly 100 pages, is a "graphic calendar," summarizing seasonality and distribution for
each species. Similar synopses have been printed elsewhere as complete books, so this is
a real bonus.
This book will be useful to a wide audience, but may be of special value as a supple-
mentary text to college courses in introductory ornithology, natural resources, or conser-
vation. A companion volume on land birds would be useful.--J. R. Jehl, Jr.
82. Guide to the Identification and Ageing of Holarctic Waders. A. J. Prater, J. H.
Marchant, and J. Vuorinen. 1977. British Trust for Ornithology 17, 168 p. (No price
given.)--This outstanding guide was written mainly for banders but will find wide use
among museum workers and field birders. It treats in detail all of the Holarctic waders
(Rostratulidae, Haematopodidae, Ibidorhynchidae, Recurvirostridae, Dromadidae, Bur-
hinidae, Glareolidae, Charadriidae, and Scolopacidae, including phalaropes), some 58 of
the world's wader fauna. For each species there is general information on distribution
and migratory habits and detailed notes on identification, aging of various age classes,
sexing, geographic variation, and measurements. A useful introduction deals with molt
and wear patterns, and their use as cues to aging. The photographs (including a color
frontispiece of the Spoon-billed Sandpiper (Eurynorhynchus pygmeus) and Lesser Sand-
plover (Charadrius mongolus)) are first rate and have been carefully chosen to illustrate age
class differences for representative species. Although the authors are somewhat less fa-
miliar with the Nearctic waders, their treatment of those species is good. The guide
includes much information that is widely scattered or not previously available. A fine
contribution; buy one.--J. R. Jehl., Jr.
83. A Guide to North American Bird Clubs. J. E. Rickert, Sr. 1978. Avian Publi-
cations, Inc., P.O. Box 310, Elizabethtown, KY 42701. 564 p. $15.00.--Billed as "the
most complete bird finding sourcebook ever compiled," this book summarizes information
on some 835 clubs from Hawaii and Alaska through the Caribbean region to Panama.
When information is available, the author includes favorite birding areas of each club, a
selected list of local birder contacts with phone numbers, membership information, club
meeting times and places, and their publications. Clearly some of this book's information
may quickly change; in fact, even before publication some names and addresses were
already out-of-date. Nonetheless, a birder traveling around the country will find the book
useful for its total contents.--David W. Johnston.
84. The Dream of Lhasa. The Life of Nikolay Przhevalsky (1839-1888), Explorer
of Central Asia. D. Rayfield. 1976. Ohio Univ. Press. Athens, Ohio. XII, 221 p. $13.50.--
Immense, remote, and mostly barred to foreigners Central Asia received no systematic
attention until the 19th century. Imperial Russia sent more gifted explorers into the
region than any other country before or since. Rayfield, a lecturer in Russian and a
specialist in Chekhov, presents the first biography in English of the most assiduous and
spectacular explorer of all. Nikolay Przhevalsky was known throughout the world in his
day, but is little noted now except in USSR. This book serves as an introduction and guide
to his explorations. As a rebel who lived for his work, he was hostile to European customs
and took on his expeditions only humble subordinates trained by himself. He avoided
marriage, chafed at civilization, and was ever anxious to be off to the wild again. Except
for his dream of reaching Lhasa, his supreme hope never realized, he worked on no
definite plan. Known now for the Przhevalsky horse, his collections revealed many other
new animal and plant species. He was not above killing many animals for sport. On one
occasion he abandoned many tons of yak meat to the wolves. His exploits had interna-
tional import, for the British saw his exploits as foretelling future Russian expansion and
acquisition and chose to counter Russia by sending their own expeditions from India. The
author consulted many and varied sources for this survey, including four volumes by
Przhevalsky, two available in English.--Leon Kelso.
85. Birdlife of the Adirondack Park. B. McP. Beehler. 1978. Adirondack Mountain
Club, Glens Falls, N.Y. 210 p. $9.95.--The Adirondack Mountains are the site of an
extensive, and surprisingly unspoiled, area of wilderness in upstate New York. As another
in the excellent series of guides to the region published by the Adirondack Mountain
Club, this book contains information on the habits, distribution, and abundance of the
more than 250 bird species recorded within the park. Introductory sections give brief
coverage of the park's history and ecology, plus an account of human impact on the region
and its birdlife. Included in these chapters are lists of avifauna by habitat as well as resident
or transient status. Most of the book is taken up by the species accounts of every bird on
record in the park. A typical entry includes status of the species, habitat, field marks,
nesting data, records in Breeding Bird Surveys, migration or wintering information, rec-
ords of maximum numbers seen, and historical comments by early Adirondack naturalists
such as T. Roosevelt, C. H. Merriam, E. H. Eaton, and A. A. Saunders. An appendix
contains a gazetteer of places mentioned in the text, coded to U.S.G.S. 15-min quadrangle
maps.
Although the book will, I hope, soon require updating, since the birdlife of many
portions of the Adirondacks has as yet been minimally studied, I give this useful reference
high praise, as indeed I recommend the beautiful Adirondacks.--B. Dennis Sustare.
86. Canada's Threatened Species and Habitats. T. Mosquin and C. Suchal (Eds.)
1977. Ottawa, Canadian Nature Federation. 185 p. $8.00.--This volume is the result of
a 1976 symposium on Canada's threatened species and habitats and includes 43 contri-
butions that span the gamut of topics from plants to mammals and oceans to mountain-
tops. Five of the chapters deal specifically with birds. Each contribution is short, averaging
only three pages, and some could more properly be considered abstracts. As a result,
some broad topics and particularly interesting subjects are treated in a superficial way.
This is not, therefore, a reference book that provides technical details on specific endan-
gered species projects or habitat preservation programs, nor is it truly comprehensive in
covering all of Canada's conservation programs. Instead it is selective and provides the
reader with a general overview.
The content of the chapters varies considerably from rather technical topics, such as
those dealing with environmental toxicants, to very general ones (conservation ethics and
policies). Especially in the latter type of chapter, usually no bibliography is included so
that the interested reader has no chance to go further into the subject. Some contributions
are conspicuously out of context, for example, a chapter dealing with the conservation of
wolves in Europe.
Perhaps the main value of the volume is that it provides a capsule overview of the
ways in which various Canadian conservationists viewed the problems of threatened
species and habitats within their country in 1976.--Stanley A. Temple.
