NEW
JERSEY/PENNSYLVANIA In
contrast to the three previous years, an unusually cold late fall and
early winter preceded the counts, and many experienced poor to miserable
weather on count day. Nevertheless, there were many records of lingering
migrants and an extraordinary list of rarities, including the region's
first Allen's Hummingbird. Only a few counts see new high species totals,
but the interesting variety made up for the unexceptional totals. Only
a single Red-necked Grebe at Long Branch was a bit surprising given the
early winter chill. Most herons and egrets cleared out early, with only
Cape May getting a good list of eight species, including Yellow-crowned
Night-Heron. Waterfowl numbers were average, but some of the less common
species were in short supply. A Greater White-fronted Goose was at Princeton,
but only three Eurasian Wigeon were located, and a pair of Blue-winged
Teal at Cape May. One each of King and Common eider were at Long Branch
and Cape May, respectively, and Barnegat's 17 Harlequin Ducks were the
only ones found. Osprey
has become an annual highlight in recent years and this season there were
two, one each in Cumberland and Lakehurst. The totals of 89 Bald Eagles
and 24 Rough-legged Hawks do not reflect the much higher numbers present
later in the winter. On an interesting conservation note, the explosion
in the population of Wild Turkey in the past 20 years is contrasted with
the decline of the Ruffed Grouse. In 1980, 13 of the 23 counts tallied
a total of 56 Ruffed Grouse (always a tough bird to find), while only
Walnut Valley had a flock of 44 Wild Turkeys. This year, Sussex County
and Walnut Valley each had a single Ruffed Grouse, but 17 counts produced
a total of 1104 Wild Turkeys.
One
Sandhill Crane discovered on the Trenton Marsh CBC lingered for several
months, but a pair located on the Elmer CBC are a part of a group of about
seven, including recent offspring, that appear to have taken up residence
in northwestern Cumberland County. Nineteen species of shorebirds were
represented, but included nothing unusual. Sandy Hook had both Laughing
Gull and Little Gull, while Cape May had another five Laughing Gulls.
Trenton Marsh recorded the state's first CBC Thayer's Gull, in addition
to a record 92 Lesser Black-backed Gulls at Florence. Sandy Hook had a
Dovekie and Oceanville a Common Murre. Cape
May produced Blue-headed Vireo for the second year in a row, this time
two birds, while a single Tree Swallow at Belleplain was the only one
of the season. Among the eight species of warblers were a Nashville Warbler
and a Cape May Warbler at Sussex County, and four Yellow-breasted Chats.
Years ago I railed about the poorly documented numbers of Chipping Sparrows
or regional CBC's, especially in the northern counties. Although there
are probably still a number of misidentifications, the tally of 406 Chippies
on 15 counts clearly indicates an increase in wintering birds. Seven
Vesper Sparrows was more than usual, and both Cape May and Lakehurst had
single Lark Sparrows. Cumberland had a Grasshopper Sparrow and Great Swamp
produced its first Le Conte's Sparrow. Lincoln's Sparrow is always a rarity
at CBC time, so the presence of individuals on three different counts
was unprecedented, but was echoed in Pennsylvania, as well. Likewise,
any bunting is an extreme rarity, but an Indigo Bunting at Cape May was
outclassed by a female-plumaged Painted Bunting at Oceanville. Winter
finches were essentially nonexistent, with a single Common Redpoll at
Belleplain and a total of five Pine Siskins on four counts. Sixty-six
counts were submitted from Pennsylvania, one less than last year, and
both the total number of species (157) and the average number of species
per count (64) were well down from last year. Also in contrast to last
year, when 24 counts reached all-time highs, this year there were no new
records and only two counts exceeded last year's totals. Southern
Lancaster County led for the fourth year in a row, but failed to break
100 for the first time since 1989. Glenolden (95), Lower Bucks (91), and
Elverson (90) were the only other counts in the 90's. Most of the counts
were held on the first or last weekend of the period and encountered generally
poor weather conditions. Erie
had the only Red-throated Loon, but neither of the rarer grebes was found.
Lehigh Valley had a Green Heron, while Lower Bucks county had both a Brant
and a Barnacle Goose, the latter of dubious origin. A pair of Trumpeter
Swans in Bernville was likely from the Ontario introduction program, and
a Long-tailed Duck at Culp was the only other waterfowl highlight. An
unprecedented total of five Ospreys was recorded, including two at Scranton.
Other raptors of note were an impressive 62 Rough-legged Hawks and two
Golden Eagles. An
Ash-throated Flycatcher at Lancaster was the bird of the season in Pennsylvania,
and only three Northern Shrikes were found. Blue-gray Gnatcatchers were
at Glenolden and Lancaster (2). Only five species of warbler were located,
half of last year's total, with a Black-and-White Warbler at Ryerson the
only really unusual one. A Le Conte's Sparrow at Lititz was new for that
count, and four Lincoln's Sparrows on three counts, Erie, Hamburg (2),
and Lehigh Valley, was an exceptional tally. A Rose-breasted Grosbeak lingered for some time at Warren, but winter finches, as in New Jersey, were almost non-existent. One Pine Grosbeak was reported from DuBois and a single Red Crossbill from Dallas. Emporium (3) and Indiana (2) had the only Evening Grosbeaks, a species whose decline in the East has been dramatic in recent years. On the 84th CBC in 1983-84, the first year that I edited these counts, the 52 Pennsylvania CBC's produced at total of 6683 birds, with only three counts missing the species. Although this is clearly an irruptive species, the recent trend is steadily downward.
