1. COAST LIVE OAK WOODLAND
ARBOLEDA COSTANERA DE ROBLE
RICHARD & LINDA BEIDLEMAN
766 Bayview Ave., Pacific Grove CA 93950
Location: California; Monterey Co.; Carmel; Garland Ranch Regional Park; 36ø30'N,
121ø45'W; Monterey Quadrangle, USGS. Continuity: New. Size: 25.0 ha. Description of Plot:
A roughly rectangular plot dominated by a heavily vegetated evergreen oak woodland. There
are a few interspersed brushland sites and two canyons with deciduous trees in the inter-
mittent creek bottom. The canopy is dominated by coast live oak, California buckeye, and
California bay. The understory is dominated by western poison oak and snowberry. The
ground cover is dominated by hedge netde and a diversity of ferns. Edge: The plot is sur-
rounded by similar woodland, but with more open brushland beyond to the W. In the broad,
flat valley to the N some distance, there is disturbed grassland and a wooded stream bottom.
Topography and Elevation: The plot is located on a relatively steep, N-facing sedimentary
foothills slope. There are two narrow N-S canyons, one with an upper pond and intermittent
creek, the other with a creeklet which was dry this season. Minimum elevation 61 m, maxi-
mum 183 m. Weather: Mean temperature 13.8øC (range 7-19øC). There were several rainy
periods, but not during visits. Precipitation was lower than normal and much less than during
the preceding winter. Coverage: 16.9 hrs; 8 visits (7 mornings, 1 afternoon): 17, 20Jan; 1,
4, 8, 11, 28 Feb; 2 Mar. Count: Ruby-crowned Kinglet, 8.4 ind./visit (8 visits); Bushfit, 7.0
(5); Chestnut-backed Chickadee, 6.5 (8); Townsend's Warbler, 6.5 (7); Cedar Waxwing, 3.4

species; 62.6 ind./visit (100 ind./40 ha). Remarks: There were consistendy three mixed-
species group territories, usually containing chickadees, titmice, kinglets, and Townsend's
Warblers, and less often Yellow-rumped Warbler, Bushtit, Bewick's Wren, Brown Creeper, and
Hairy Woodpecker. Most species favored the canopy. Rufous-sided Towhee, Wrenfit, Bewick's
Wren, and Scrub Jay were brushland indicators, while Winter Wren and Steller's Jay were
only in the canyon riparian ecosystem. Species of birds occupying the N valley, with its dis-
turbed grassland and wooded creekbottom, seldom entered the oak woodland. Acknowledg-
ments: Thanks to District Naturalist Natalie Schaefer for pertinent information.

< 0.01) declines in Red-bellied Woodpeckers, Carolina Wrens, and Golden-crowned Kinglets.
We suspect this was due to the colder winter. The third week of January was very cold, with
the low in Cincinnati (-31øC) within 1øC of a record. Spring migration had already started
by our last visit, as judged by the arrival of robins and grackles in the Cincinnati area. Three
of the four American Robins recorded were found on 19 February. Other Observers: Wayne

Owl, 0.1 (1); Golden-crowned Kinglet, 0.1 (1). Total: 31 species; 123 ind./visit (273 ind./40
ha). Remarks: Basswood and hackberry fruits were unusually abundant early in winter. North-
ern Cardinal numbers recovered after a dip last year. Other significant increases occurred
in Mourning Dove, Downy Woodpecker, Northern Flicker, Red-breasted Nuthatch, and Eu-
ropean Starling. Precipitous drops occurred in the numbers of Cedar Waxwing, House Spar-
row, and Golden-crowned Kinglet. The kinglet was seen only once, the lowest abundance
since the study was begun in 1989. Red-shouldered Hawk and Common Redpoll were new
to the study. There was no obvious mortality due to the severe weather; even the "sensitive"
Carolina Wrens appeared to survive the winter. Yellow-rumped Warbler was not detected for
the first time.

average temperature for January (-11.7øC) was the second lowest on record and was 5.5øC
below the norm. Temperatures averaged 4øC below the 30-yr average (-2.1øC) from Decem-
ber through March. Snowfall averaged 21.7 cm above the norm per month. Source: Envi-
ronment Canada. Coverage: 10.0 hrs; 8 visits (6 mornings, 2 afternoons): 11, 24, 26 Dec; 22

0.1 (1); woodpecker species, 0.1 (1); American Goldfinch, 0.1 (1). Total: 14 species; 14.6
ind./visit (45.0 ind./40 ha). Remarks: The extremely cold winter (especially January) likely
accounted in part for the plot's third lowest total count (117 individuals, 11-yr average is
191). The total of 14 species is approximately 2.5 below average. Bark foragers dominated
once again, totaling 84 individuals (72% of total, 5 species). Black-capped Chickadees ac-
counted for 46% of the total individuals. Double-crested Cormorant (11 December) was new
to this plot.

was denser than in Mature Longleaf Pine Forest II, which is 100 m to the E. Large flocks of
Yellow-rumped Warblers foraged throughout the forest, particularly on waxmyrtle which was
fruiting. A large mixed flock of White-throated Sparrows and Northern Cardinals was active
around the titi stringer and a dried-up ephemeral pond. Wood Ducks were noticeably scarce
because of the dry conditions. Red-headed Woodpeckers, which are usually rare to absent
in this forest during the winter, were abundant. Acknowledgments: Thanks to Larry Carlile

The ephemeral pond was completely dry this year. Weather: Mean temperature 5.0øC (range
0-12øC). Winds were gusty on two visits. It was overcast or foggy during three visits. Coverage:
16.6 hrs; 8 visits (mornings): 10, 11, 24, 25, 26, 27 Jan; 1, 2 Feb. Count: Yellow-rumped

Remarks: The plot was subjected to a prescribed burn on 15 June 1993. Grasses (especially
wiregrass) responded by flowering profusely. The resulting seed crop, in addition to a sparse
litter layer, may have accounted for increased abundances of Chipping Sparrow, Rufous-sided
Towhee, and Northern Cardinal compared to last year. Yellow-rumped and Palm Warbler
numbers increased dramatically compared to last year. The dry pond accounted for the
decrease in Wood Duck numbers. Four Red-cockaded Woodpecker clans foraged on the plot.

KENNETH MOORE
Walnut Creek Apts., Apt. 52, DeRidder LA 70634
Location: Louisiana; Vernon Parish; Ft. Polk; Fullerton Area; 31ø5'N, 92ø58'W; Fullerton Lake
Quadrangle, USGS. Continuity: New. Size: 25.0 ha. Description of Plot: A square plot (500
x 500 m) with an open park-like stand of longleaf pine estimated to be between 61 and 100
years of age. There is very little understory. The ground cover is dominated by little bluestem
with a small mixture of other grasses and forbs. A quantitative vegetation survey based on
the method described by F.C. James & H.H. Shugart, Jr. (1970. Aud. Field Notes 24:727-736)
yielded the following results: Trees, 7.6 cm diameter and over, based on 6 0.04-ha circular
samples, 34/ha; total basal area 4.7 m2/ha. Species comprising 100% of the total number of
trees [figures after each are trees/ha, relative density (%), relative dominance (%), and
frequency (%)]: longleaf pine, 19, 56, 81, 83; loblolly pine, 8, 23, 13, 17; laurel oak, 3, 10,
1, 17; sweetgum, 6, 8, 3, 17; southern red oak, 1, 2, 0.2, 17; shortleaf pine, 1, 2, 2, 17; standing
dead, 1, 2, 2, 17. Trees by diameter size class [figures after each are trees/ha, relative density
(%), basal area in m2/ha, and relative dominance (%)]: A (7.6-15.2 cm) 9, 26, 0.1, 3; B
(15.2-22.9 cm) 2, 6, 0.1, 2; C (22.9-38.1 cm) 9, 28, 1.1, 22; D (38.1-53.3 cm) 11, 32, 2.8,
61; E (53.3-68.6 cm) 1, 4, 0.6, 12; Shrub stems/ha, 457. Ground cover, 88%. Canopy cover,
61%; average canopy height, 19.0 m (range 9-29 m). Two small intermittent streams start
just inside the plot and flow out; small bogs occur around each stream head. The stream
heads provide the only dense cover found in the plot. Edge: Most (95%) of the plot's perim-
eter is bordered by the same habitat; the other 5% is a stream bed that contains loblolly
pine, sweetbay, and oaks. The plot lies within a tract of similar habitat > 500 ha in size.
Topography and Elevation: The plot has an uneven W-facing slope of < 5%. Minimum
elevation 84 m, maximum 93 m. Weather: Mean temperature 4.8øC (range -2-13øC).January
temperature was above normal, precipitation was twice normal. February temperature was
near normal, precipitation below normal. Coverage: 15.2 hrs; 8 visits (mornings): 4, 5, 6Jan;
1, 3, 4, 7, 9 Feb. Count: Pine Warbler, 7.4 ind./visit (8 visits); Red-winged Blackbird, 5.0 (1);
Yellow-rumped Warbler, 3.6 (6); White-throated Sparrow, 3.4 (5); Red-cockaded Woodpecker,
2.0 (6); American Goldfinch, 1.5 (2); Ruby-crowned Kinglet, 1.1 (5); Carolina Chickadee,
1.0 (5); Yellow-bellied Sapsucker, 0.9 (6); American Crow, 0.9 (1); Carolina Wren, 0.9 (5);

0.3 (2); Song Sparrow, 0.3 (1); Great Horned Owl, 0.1 (1); Pileated Woodpecker, 0.1 (1);
Winter Wren, 0.1 (1); Brown Thrasher, 0.1 (1). Total: 26 species; 32.9 ind./visit (52.6 ind./
40 ha). Remarks: Fewer birds were found in the stream head vegetation in February than
in January. A 16.5 cm rainfall on 27 January cleared the stream beds of leaf litter, making
them less attractive to ground-foraging birds.

Plot: See J. Field Ornithol. 61 (Suppl.):46 (1990). Weather: Mean temperature -18.0øC (range
-30-0øC). Mean snow depth 62.4 cm (range 15-102 cm). Light snow or snow squalls during
two visits. January 1994 was the coldest month recorded in this region of the state in 100
years. The average daily temperature was -18øC, a full 6øC departure from normal. Total
snowfall for January was 110 cm (150% of normal). The first two weeks of February contin-
ued colder and snowier than average; the remainder of the winter fell within normal limits.
The pond and small stream were frozen throughout the count period. Source: Northeast

Common Raven, 0.2 (2); Ruffed Grouse, 0.1 (1). Total: 12 species; 11.3 ind./visit (28.3 ind./
40 ha). Remarks: Count totals for most species were significantly lower than averages for a
second consecutive year. Several visits (5, 6, 7, 8) yielded no bird sightings. Again, severe
weather conditions in January and early February were probably a major factor in the lower
counts. Common Redpolls made their first showing in five years; Evening Grosbeaks were
absent for the first time in five years. Acknowledgments: I thank Boise Cascade for their
continued support of this project.

Redpoll was a new species on the plot. The total number of individuals was the lowest ever,
with chickadees at only half of the 9-yr average number. Multiflora rose hips along the W
edge provided some food, but in general the poor food supply (the cone crop was generally
poor) and severity of the winter probably caused the low counts. Other Observer: Peter
Gradoni. Acknowledgments: Appreciation to Cynthia Clements and Phil Foster for permis-

1974; 20 yr. Size: 16.6 ha. Description of Plot: See Am. Birds 28:699-700 (1974). Weather:
Mean temperature -3.8øC (range -9-9øC). Mean snow depth 31.0 cm (range 0-57 cm).
The ground was bare on one visit. There were flutries on two visits. Average temperature in
December (-3.9øC) was about normal; January (-11.5øC) was 8øC colder than normal.
Snowfall in December (43 cm) was 2 cm above normal; January (81 cm) was 44 cm above
normal. Source: Alfred Cooperative Weather Station. Coverage: 12.8 hrs; 8 visits (3 mornings,
5 afternoons): 17, 28, 31 Dec; 1, 10, 11, 22, 23Jan. Count: Black-capped Chickadee, 9.1 ind./
visit (8 visits); Red-breasted Nuthatch, 2.8 (8); Blue Jay, 1.3 (6); Brown Creeper, 1.1 (5);
Common Redpoll, 0.8 (1); Hairy Woodpecker, 0.5 (4); American Crow, 0.4 (3); Evening

(1); Golden-crowned Kinglet, 0.1 (1); Dark-eyedJunco, 0.1 (1). Total: 13 species; 16.9 ind./
visit (40.7 ind./40 ha). Remarks: Tufted Titmouse was a new species, bringing the 20-yr
cumulative list to 31 species. Only Black-capped Chickadee and Red-breasted Nuthatch were
observed on every visit. Severe cold and heavy snow cover in January made censusing diffi-
cult, even on snowshoes. The total number of individuals was the second lowest since 1974.
The poor food supply (the cone crop was poor) and severity of the winter probably were
the major reasons for the low count. Selective logging of a section of Norway spruce and
white pine began in September but was not carried on during the study period. Acknowl-
edgments: Appreciation to Rick Walker for weather data.

Location: Tennessee; Putnam Co.; Cookeville; City Lake Natural Area (Old Cookeville Filtra-
tion Plant); 36ø8'N, 85ø27'W; Cookeville East Quadrangle, USGS. Continuity: Established
1990; 5 yr. Size: 10.2 ha. Description of Plot: SeeJ. Field Ornithol. 62(Suppl.):17 (1991) and
63(Suppl.):18-19 (1992). A 4-ha stand of mature hardwoods along the NW boundary was
clear-cut in summer 1993. Weather: Mean temperature 0.6øC (range -5-7øC). About 8 cm
of snow cover on 21 January with lesser amounts on 23 and 24 January. Drizzle during one
visit. It was wetter and colder than normal in January. The temperature reached -24øC on
19 January, a record for that date. Coverage: 14.0 hrs; 10 visits (mornings): 10, 11, 21, 23,
24, 31 Jan; 4, 6, 7, 12 Feb. Count: European Starling, 6.8 ind./visit (8 visits); Northern
Cardinal, 5.4 (10); Canada Goose, 4.9 (3); Tufted Titmouse, 4.7 (10); American Goldfinch,

Sparrow, 0.1 (1); Purple Finch, 0.1 (1). Total: 43 species; 65.1 ind./visit (255 ind./40 ha).
Remarks: Development of the site continues; since last report the settling basins of the old
filtration plant were covered with a wooden deck (15 m x 15 m). The plot is also used as a
collection site for old Christmas trees; on several days a wood chipper ran for 3-4 hours.
Waterfowl numbers were increased by the freezing of most area lakes and ponds; the stream
that runs through the plot remained open and kept part of the lake open, providing feeding
and roosting areas for geese and ducks.

Plot: See J. Field Ornithol. 63(Suppl.):88 (1992). Weather: Mean temperature 10.3øC (range
2.9-21.7øC). Precipitation for 1993 was deficient by 38 cm (mostly during the warm part of
the year). Precipitation for January and February 1994 was in excess by 0.82 cm. Snow flurries
were seen twice. Temperatures were about average but colder during the first 20 days of
January, minimum -14.5øC (19January), maximum 23.9øC (early February). Coverage: 40.0
hrs; 20 visits (13 mornings, 5 afternoons, 2 evenings): 2, 6, 9, 13, 24, 28 Dec; 10, 21, 23, 24,
27, 29 Jan; 3, 6, 9, 17, 19, 20, 25, 28 Feb. Coverage includes 60 partial visits of 0.33 hrs each.

0.1 (2); Killdeer, 0.1 (1); Fish Crow, 0.1 (1). Total: 37 species; 241 ind./visit (643 ind./40
ha). Remarks: Less habitat destruction in cemetery lately. Considerable interspecific antag-
onism effects populations of many birds, i.e. House Finch caused loss of Purple Finch and
some House Sparrows. Mockingbird is probably responsible for fewer robins and thrashers.
Crows harass Red-tailed Hawks, but Cooper's Hawks fight back at them. At least two Red-
tailed Hawks were on the plot because both an adult and an immature were seen. Blackbirds
that were not feeding on the plot were not counted. A coyote (Canis latrans) was seen once.

composition was similar to that of previous years, except Pine Siskins were absent. One Myrtle
Warbler type of Yellow-rumped Warbler was seen. One Blue-crowned Conure occurred on
one visit, possibly a recent escapee. We saw significantly fewer species and had lower counts
during the evening visit.

Quadrangle, USGS. Continuity: Established 1971; 24 yr. Size: 51.8 ha. Description of Plot:
See Am. Birds 25:644-645 (1971) and J. Field Ornithol. 65(Suppl.):26-27 (1994). The Gen-
esee River has cut into the plot another 23 m, removing farmland in mid-plot and some
trees on the S end and N of mid-plot. The beavers moved out of the study area. Weather:
Mean temperature -2.6øC (range -7.8-0.6øC). Mean snow depth 15.2 cm (range 0-45.7
cm). The ground was bare on three visits. Temperatures averaged 1.4øC below normal with
Lake Erie freezing on 1 January (on time). From 21 December, temperatures almost consis-
tently near -18øC allowed deep snow accumulation. Precipitation, mostly snow, was 27.9 cm
above normal. The Genesee River and nearly all pools remained at least partly open. Source:
Wellsville Water and Light. Coverage: 16.1 hrs; 8 visits (7 mornings, 1 afternoon): 2, 6, 15,
20 Dec; 3, 11, 24Jan; 7 Feb. Cotant: House Finch, 19.4 ind./visit (8 visits); Ring-billed Gull,

68.9 ind./visit (53.2 ind./40 ha). Remarks: Comparing 1994 results with the 1971-1993 av-
erage (in parentheses): total species, 28 (26); mean ind./visit, 68.9 (146); and excluding
American Crow and Snow Bunting, 63.4 (104). Although the number of species increased,
that of individuals was 47% of the 23-yr average. At least partial causes for the low count
were the deep snow cover and scarcity of food such as no top dressings, wild grapes, or
rabbits. Also, box elder pods, sycamore fruits, and weed seeds were soon depleted. However,
in addition to plentiful sumac fruit, there were two reliable feeders at the plot edge. Northern
Flicker and Eastern Screech-Owl were new to the study, with feathers but no body parts of
the latter being found near the river. Acknowledgments: Thanks to Dr. Stephen W. Eaton
for identifying the feathers of the Eastern Screech-Owl kill, and to Calvin Maybee for per-
mission to use his property.

Location: Ontario; Municipality of Hamilton-Wentworth; Dundas; Dundas Valley Plot #1;
43ø15'N, 79ø54'W. Continuity: New. Size: 5.8 ha. Description of Plot: See J. Field Ornithol.
60(Suppl.):14 (1989). Because of recent urban expansion into the plot's E sector, this very
productive sector has been eliminated. The plot has now been extended to the W, almost
to the Dundas Valley Plot #2. The S half and part of the N half of this new sector add woods
and woods-thicket to the plot, leaving the predominant field habitat somewhat reduced.
Edge: The S edge of the new W sector is continued woods or woods-thicket. Bordering the
W and N edges of this sector is an open area plus shrubs or small trees of varying densities.
Weather: Mean temperature -3.3øC (range -12-3.5øC). Mean snow depth 17.8 cm (range
0-40 cm). The ground was bare on one visit. It snowed during two visits. The total of average
temperatures for this very cold winter was -24.3øC (15.8øC below the 30-yr mean), averaging
4øC below normal per month. The average temperature for January (-11.7øC) was the sec-
ond lowest on record. Snowfall averaged 21.7 cm over the norm per month, with a total
increase of 86.6 cm. Source: Environment Canada. Coverage: 8.3 hrs; 8 visits (6 mornings,
2 afternoons): 20, 28, 31 Dec; 9, 29 Jan; 5 Feb; 8, 14 Mar. Count: Black-capped Chickadee,
7.3 ind./visit (8 visits); Pine Siskin, 2.5 (2); American Robin, 1.3 (3); American Tree Sparrow,
1.3 (4); Golden-crowned Kinglet, 1.0 (2); Northern Cardinal, 0.6 (2); Pine Grosbeak, 0.5
( 1 ); Hairy Woodpecker, 0.3 (2); Cedar Waxwing, 0.3 (1); American Goldfinch, 0.3 (2); Downy
Woodpecker, 0.1 (1); BlueJay, 0.1 (1); House Finch, 0.1 (1). Total: 13 species; 15.5 ind./
visit (107 ind./40 ha). Remarks: The changes in size and vegetative composition have re-
suited in a new continuity designation. The 124 total individuals is the second lowest for the
plot, approximately 100 birds below the 9-yr mean (this year plus the eight years of the
original plot). The severe weather and shifting of the plot away from area feeders and more
sheltered conditions, may have reduced numbers considerably. House Finch numbers plum-
meted from a high of 162 individuals (1992-93) to one bird this year. Similarly, cardinal
numbers fell from 51 to 5. Chickadees were the most numerous species with 58 total indi-
viduals (36% above the 9-yr mean). With 56% of the total individuals, bark foragers (4
species) outnumbered other feeding groups, perhaps indicating the plot's altered vegetative
character.

of Plot: See J. Field Ornithol. 65(Suppl.):31 (1994). The only major disturbance to the area
in the last 30 years was the recent removal of vegetation from the S and E portions of the
plot. Large areas of mature laurel sumac and a large area of prickly pear cactus were re-
moved. Now there is a small cactus patch in the S-central border. Weather: Mean temperature
16.1øC (range 12.7-21.1øC). Generally clear with high clouds. Less than 10 cm of rain fell

165 ind./visit (499 ind./40 ha). Remarks: Anna's Hummingbird numbers dropped between
the fourth and fifth visits. I suspect females were incubating eggs because the majority of
birds seen after 22 January were males. The plot has very thick underbrush, and visibility is
limited in some areas. Many birds were identified by song alone, therefore, some non-vocal,
secretive species, such as Bewick's Wren and Hermit Thrush, may be under represented in
this study. Birds which feed on the seeds of laurel sumac and the insects on the bush, such
as House Finch and White-crowned Sparrow, were fewer in number. Species that use the
cactus as foraging sites or as protection, such as Cactus Wren and California Thrasher, were
also fewer in number. Other Observer: Janice L. Ryan.

previous years, but lower than in 1991 (34). Bewick's Wren (58% increase), Rufous-sided
Towhee (+ 36%), Golden-crowned Kinglet ( + 150%), Hermit Thrush (+ 74%), Fox Sparrow
(+417%), and Bushtit (+178%) numbers were higher than last year and were all-time highs.
Wrentit density increased 28% to the highest recorded density, correlating with an extremely
productive breeding season (see 1993 Breeding Bird Census). Anna's Hummingbird detec-
tions increased five and one-half fold from last year to their highest recorded densities. The
number of American Robins was a seven fold decrease from last year when they were at their
highest recorded density; this was the only marked decrease, as they returned to numbers
more similar to other years. Dark-eyed Juncos were detected on the plot for the first time in
11 years and Red Crossbills were observed for the first time. Acknowledgments: We thank

Quadrangle, USGS. Continuity: Established 1984; 11 yr. Size: 8.0 ha. Description of Plot: See
Am. Birds 39:119 (1985) and J. Field Ornithol. 63(Suppl.):109 (1992). Weather: Mean tem-
perature -3.1øC (range -10-5øC). Mean snow depth 25.8 cm (range 0-46 cm). The ground
was bare on two visits. Temperatures averaged 1.4øC below normal with Lake Erie freezing
on 1 January (on time). Precipitation, mostly snow, was 27.9 cm above normal. From 21
December, temperatures almost consistently near -18øC allowed deep snow accumulation.
The intermittent stream was open on five visits because the heavy snow cover prevented the
ground from freezing. Source: Wellsville Water and Light. Coverage: 7.7 hrs; 8 visits (morn-
ings): 3, 16, 31 Dec; 13, 14Jan; 3, 17, 24 Feb. Count: Cedar Waxwing, 9.4 ind./visit (1 visit);

0.1 (1); Evening Grosbeak, 0.1 (1). Total: 19 species; 21.5 ind./visit (108 ind./40 ha). Re-
marks: The number of species was slightly above normal, but that of individuals was 63%
below the 1984--1993 average. This low count is a reflection of the early scarcity of wild food,
including rose hips, hawthorn fruits, and goldenrod galls, as well as the persistent and often-
crusted snow. However, there was plentiful ear-corn in the open field off the E edge of the
plot during the first two visits. Decreasing numbers of birds seem to be the norm. Cooper's
Hawk, Common Raven, and Common Redpoll were new to the study. Tracks of white-tailed
deer, rabbits and a fox were noted. Acknowledgments: Thanks to Gail and Victor Funk for

Location: Pennsylvania; Clinton Co.; South Avis; South Avis Fields; 41ø10'N, 77ø17'W;Jersey
Shore Quadrangle, USGS. Continuity: Established 1983; 12 yr. Size: 40.5 ha. Description of
Plot: See Am. Birds 38:56-57 (1984). This year the fields were composed of corn residue
(27.9 ha), soybean residue (9.9 ha), fallow (1.9 ha), and hay (0.8 ha). Weather: Mean tem-
perature -3.4øC (range -8.3-3.3øC). Mean snow depth 21.1 cm (range 0-44 cm). Total
snowfall for the winter was > 222 cm; there were seven days when the temperature was below
-17.8øC (the lowest recorded was -25.6øC). The ground was snow covered from 24 Decem-
ber through 2 April, except for 3 January when it was about half covered. The fields had >
20 cm of snow on five visits. There was snow during one visit and light snow during another.
Coverage: 6.5 hrs; 10 visits (8 mornings, 2 afternoons): 1, 3, 13, 17, 22, 24, 25, 30, 31 Jan; 5
Feb. Count: Horned Lark, 23.0 ind./visit (2 visits); Rock Dove, 11.7 (3); Mourning Dove, 9.9
(2); Amerpican Crow, 1.1 (3); Common Raven, 0.2 (1); Snow Bunting, 0.2 (1); Northern
Harrier, 0.1 (1); Rough-legged Hawk, 0.1 (1). Total: 8 species; 46.3 ind./visit (45.7 ind./40
ha). Remarks: On 25 January, the fields were covered with 12.3 cm of snow except where it
had melted around the bases of the corn stubble, producing small pockets of exposed field.
The large number of Rock Doves on that date were feeding around these short lengths of
stubble. An ice storm preceding the 30 January visit had mostly filled in these depressions,
possibly eliminating the availability of food. No birds were recorded on the 30 January visit,
or on any of the five visits where the snow depth exceeded 20 cm.
