This is the Vermont bird report for Friday, September 19, 2003, covering the
period September 12-18.
The past week was fairly quiet, wiht no pronounced influxes of migrant
shorebirds or passerines. In fact, shorebird reports were nonexistent.
Raptors provided the most conspicuous evidence of southward migration.
Two hawkwatches on Mt. Philo demonstrated how dramatically migration can
in a short timespan. During a two-hour watch on Sep. 13, 17 BROAD-WINGED
were counted, while four days later, 1,222 individuals were tallied. Other
species reported from Mt. Philo on these two dates were OSPREY (4 on 9/11,
9/17), BALD EAGLE (1 on 9/17), NORTHERN HARRIER (1 on 9/13, 2 on 9/17),
SHARP-SHINNED HAWK (1 on 9/13, 17 on 9/17), COOPER'S HAWK (3 on both 9/13 and
9/17), RED-TAILED HAWK (4 on 9/13, 1 on 9/17), and AMERICAN KESTREL (5 on
9/17). Notable raptors reported from Mt. mansfield on Sep. 11 included 1
NORTHERN HARRIER, 5 AMERICAN KESTRELS, and 1 MERLIN.
At Lake Bomoseen in Hubbardton on Sep. 12, highlights included 3 PIED-BILLED
GREBES, 9 GREAT BLUE HERONS, 94 WOOD DUCKS, 2 GADWALL, and 1 COMMON MOORHEN.
At nearby Love Marsh in Castleton on this date were another 28 WOOD DUCKS. A
solitary GREAT EGRET was observed on the Winooski River on the Williston/South
Burlington line on Sep. 13
The only shorebird or larid reports were of 5 BLACK-BELLIED PLOVERS at Delta
Park on Sep. 16 and 5 CASPIAN TERNS (one group of 4 and a lone bird) moving
southward along Lake Champlain at Charlotte Town Beach on Sep. 17.
RUBY-THROATED HUMMINGBIRDS continue to linger, with Sep. 13 reports from
Lincoln, Waitsfield and Williston, and a feeder bird in Georgia on Sep. 17
Passerine migration continues to be unremarkable, with some breeding residents
apparently still on territories. Reports of singing birds during the past
included YELLOW-THROATED VIREO (3) and WARBLING VIREO (2) at Lake Bomoseen on
Sep. 12, and single EASTERN WOOD-PEWEE and RED-EYED VIREO in Norwich on Sep.
18. A RUSTY BLACKBIRD at the south end of Berlin Pond on Sep. 13 may have
the week's most unusual bird, mainly because of its early date outside the
species' known VT breeding range. Probable migrant warblers included 3
CHESTNUT-SIDED and 6 MAGNOLIA WARBLERS at Union Village Dam in Thetford on
15. In S. Duxbury on the 15th, 1 MAGNOLIA, 3 BLACK-THROATED BLUE, and 2
BLACKBURNIAN WARBLERS were observed. Across the Connecticut River in Hanover,
also on Sep. 15, a CAPE MAY WARBLER and PRAIRIE WARBLERS were almost certainly
transients, as was a NORTHERN PARULA at Delta Park in Winooski on Sep. 16. An
early LINCOLN'S SPARROW was reported from S. Duxbury on the 15th.
