EDITED BY HERBERT W. KALE At the recent A.O.U. meetings in Oklahoma your editors discussed at length with the council the future of this periodical literature section, which has more than doubled in length in the last decade. As the cost per page of producing Auk has also doubled in the same period, the section has become an expens:.ve luxury. Various measures of paring it down to reasonable size were proposed, including the suggestions that we list titles only, or delete it and devote the space entirely to new research. The section's principal value has been to save researchers the trouble of going through periodicals for material of concern to them published since the last Aves volume of the Zoological Record, which is perennially 5 or 6 years behind time--also those in Biological Abstracts and Wildlife Review, which are only slightly more current. It has long been our policy to list articles from Condor and Wilson Bulletin by title only, on the grounds that American ornithologists have ready access to them. We long ago stopped listing individual entries in the annual or 10-year indexes, vhich greatly reduces the section's efficiency and usefulness, but is simply too costly for us. The section that follows is frankly a compromise and an experiment--deleting all American publications, which most researchers should have readily available and are covered by the other abstracting services or listed in Current Contents. While we are well aware that occasionally fine papers are published in minor state or local journals that the main compiling agencies overlook (we will try to note the appearance of new periodicals and abstract such important exceptions as Forsythe, p. 197), we feel we are doing the majority of our readers the greatest possible service within our means by listing and abstracting only the foreign periodicals. We welcome comments, criticisms, and suggestions from our readers for keeping this section as useful as possible within our financial resources.--EI)s. A NEW PERIODICAL PACIFIC SEABIRD GROUP BULI,. vol. 1. NO. 1. January 1974--"The Pacific Seabird Group's primary function is to increase the flow of information among persons interested in Pacific seabirds . . . The Group will provide coordination and stimulation of the field activities of its members rather than initiating any field programs of its own. For the time being, at least, the Group will be primarily concerned with the west coast of North America and adjacent areas of the Pacific." At present, working committees are concerned with coordination of activities in colony censusing, beached bird surveys and disasters, and pelagic observations and sea-vatches. Regional reports (from Alaska to Mexico) list a surprising number of studies under way: Alaska 19, British Columbia 22, Washing- ton 8, Oregon 7, California 35, Hawaii 2. Conservation policy statements concern seabird conservation in the Gulf of California, and Alaska oil and seabirds. A book review, sundry news items, and a membership list, with research topics of the 152 charter members complete this issue. The bulletin is planned to be issued semiannually, in January and September, by the Secretary, GFORCF J. Dvo:3/4, U.S. Fish and Wildlife Service, 1412 Airport Way, Fairbanks, Alaska 99701. Address: 35 1st Court SW, Veto Beach, Ftorida 32960. BEHAVIOR AI, OCK, J. 1973. Cues used in searching for food by Red-winged Blackbirds (Agelaius phoeniceus). Behaviour 46: 174-188.--Food maze experiments with hand- reared birds indicate that they are sensitive to both loeational and visual cues and learn to use them while foraging. Discusses results in the context of Tinbergen's search image hypothesis.--F.E.L. BAKER, M. C. 1973. Stochastic properties of the foraging behavior of six species of migratory shorebirds. Behaviour 45: 242-270.--A statistical description of the temporal and sequential organization of foraging behaviour based on analysis of movies of Calidris minutilla, C. pusilla, C. alpina, Limnodromus griseus, Tringa flavipes, and Charadrius semipalmatus made on the breeding and wintering grounds.

Communal feeding of nestlings in the Mexican Jay (Aphelocoma ultramarina): interflock comparisons. Anim. Behav. 20: 395-403.--Based on color-banded birds, helpers accounted for 46-68% of feeding at five nests, and at some nests certain individuals brought more food more frequently than did the parents.--F.E.L. BRUEN, K., ANn D. W. DUNHAM. 1973. Effects of social stimuli on nest building in the Zebra Finch (Poephila guttara). Anim. Behav. 21: 183-190. The sight and sound of a conspecific is conducive to nest building in domestic males but sounds from unseen nearby conspecifics seem to block this stimulating effect by evoking a flocking tendency that increases general activity and reduces nest building.--F.E.L. BUCKLE3/4, P. A., ANn F. G. BUCKrEV. 1972. Individual egg and chick recognition by adult Royal Terns (Sterna maxima maxima). Anim. Behav. 20: 457-462.-- Incubating adults consistently recognized their own eggs when placed in an adjacent nest and 3 of 4 chicks were unrecognized by their parents until the silent chicks vocalized.--F.E.L. CATCHPOLE, C. K. 1973. The functions of advertising song in the Sedge Warbler (Acrocephalus schoenbaenus) and the Reed Warbler (A. scirpaceus). Behaviour 46: 300-320.--Results of observation and playback experiments indicate that the main function of persistent song in unpaired males is sexual attraction of females, and that intermittent song from paired males functions in territorial defense. (Author's summary.)--F.E.L. CAWTE, K. G. 1973. Moorhen attempts to drown Ringed Plover. Brit. Birds 66: 78.--Gallinula chloropus with chicks held a Charadrius hiaticula under water. --J.J.D.

Behav. 21: 236-246.--The results of an exploration of the brain of juvenile Larus argentatus and L. fuscus with electrical stimulation are compared with normal agonistic behaviour. Proposes that the secretion of "liquormones" is responsible for the changes in mood that followed stimulation of the neuroven- tricular interface area of the brain. (Author's abstract.)--F.E.L. DUNC^N, I. J. H., AU D. G. M. Woou-Gusm 1972. An analysis of displacement preening in the domestic fowl. Anim.

(Author's abstract.)--F.E.L. PR3/4, V. 1973. The auxiliary social system and its effect on territory and breeding in Kookaburras. Emu 73: 81-100.--Kookaburras live in pairs, or in family groups that include auxiliary ( helper) members. Fully one-third of the adult population is composed of these "auxiliaries," which are nonbreeding progeny of previous years that associate with their parents, assisting in territorial defense and attending the young. Territories of groups are larger than those of pairs, effectively reducing the breeding potential of the population by one-third. Nests with auxiliaries produced more fledglings (2.3 against 1.2 for a pair without auxiliaries), and juveniles from nests attended by auxiliaries showed less mortality than those of pairs. Because auxiliaries contributed up to a third of nest attendance time, and brought up to 60% of food to the young, pairs of such "families" have considerable free time and are able to rear a second brood in good years. Discusses population regulatory functions.--L.L.S. P^3/4E, R.P. 1973. Vocal mimicry of the Paradise Whydahs (Vidua) and response of female whydahs to the songs of their hosts (Pytilia) and their mimics. Anim. Behav. 21: 762-771.--The approach response of isolated, photostimulated female whydahs to the recorded songs of various Pytilia species was strongly specific to the correct host species and the mimetic male whydah song. Author suggests that mimetic songs of males and the responses of females are behavioral isolating mechanisms among whydah species.--F.E.L. PEEZ, F. W. 1972. An experimental study of the territorial function of vocal and visual display in the male Red-winged Blackbird (Agelaius phoeniceus). Anita. Behar. 20: 112-118.--Territorial males that were either muted surgically or had their epaulets altered were less successful than normals in maintaining territory. The ability of experimentais to maintain their territories differed seasonally. Author proposes a three-level territorial defense system based on advertising song, display, and finally, chase and attack.---F.E.L. PEEZ, F. W. 1972. The effect of tranquilization upon territory maintenance in the male Red-winged Blackbird (Agelaius phoeniceus). Anim.

Numbers of the former two species had increased since 1957 and were the main aircraft strike hazards. Ring-billed and Herring Gulls fed mainly at eight inland dumps and landfills. They moved inland and up rivers in the mornings from coastal roosts on beaches, islands, and spoil banks, and returned to the roosts in the evening. Laughing Gulls fed mainly along the coast, mostly on refuse from shrimp trawlers. Gulls tended to frequent exposed mudflats and sandbars at low tide, and often rested on wet airfields and pavements during rainy, windy weather. (From author's summary.)--D.M.F. G^ER, W. 1973.

Ostrich 44: 191-261.- Part 2: Nest architecture and social organization. Many birds cooperate in building the nest structure, and the individual pairs' brood chambers are built mainly by the pairs alone. Juveniles help their parents feed the young of later broods and sometimes may take over these brood chambers themselves. Part 3: Breeding biology and moult. Detailed study of annual cycles and breeding of Philetarius socius. Breeds only with substantial rains. Clutch size is larger after good rains. First broods help their parents rear later broods, and with fourth broods the young from the earlier three may all help feed. Wing molt takes most of the year to complete. Part 4: Predators, parasites and symbionts. Cobras live in the nest structures of the colonies and are the main predator on the young. Ectoparasites are uncommon in these birds. Other species of birds often nest in the weaver nest structures, particularly the Pygmy Falcon, Poliohierax semitorquatus, a bird that the weavers resent but which may help keep away snakes. Part 5: Food, feeding and general behaviour. Philetarius socius eats mainly insects (termites, caterpillars, and grasshoppers). Young are reared entirely on insects. The members of a colony usually feed within 1.5 km of their nest structure.--R.B.P. M^:rzoc:s, J. G. 1971. Goose feeding and cellulose digestion.

Toward the breeding season most males switch to sleeping in shrubs, presumably because it is safer there and occupying a potential nesting site would be dysgenic. A second peak in hole-sleeping coincides with molt, when some 20 to 40% of the females and 50 to 65% of the males sleep in holes. The gain in energy conserved probably outweighs the danger of sleeping in a hole. (English summary.)--N.A.M.V. YorTov, Y., G. M. DUNNE, Am) A. ANDERSON. 1974.

Emu 73: 157-176.--An im- portant paper on parrot relationships, although, as in so many such cases, the author fails to explain his concepts of the various taxa. These three subfamilies seem to be monophyletic (are they really separable?). Neotropical parrots sug- gested by other authors to be related to these Australasian parrots are considered more closely related to other Neotropical parrots, and only convergent upon Australian platycercine parrots. The Platycercinae are considered "primitive," having given rise to the Loriinae, early stock of which perhaps gave rise to the Nestorinae. Melopsittacus and Pezoporus are placed in the Platycercinae, the Psittaculirostrinae is erected for Psittaculirostris (regarded as intermediate between platycercines and lories), and Lathamus is placed in the Loriinae. The linear order, the author suggests, namely Platycercinae, Psittaculirostrinae, Nestorinae, Loriinae, seems odd--his phylogenetic views instead suggest Platycercinae, Psit- taculirostrinae, Loriinae, Nestorinae.--L.L.S.

Intra- specific variation of P. lawesii is treated. These montane birds perhaps form a superspecies, but this is not to infer simple allopatric speciation; rather, the authors suggest that complex introgressive hybridization and recombination in geographically isolated stock of "hybrid" origin probably played a role in the evolution of these birds of paradise.--L.L.S.
