ABSTRACT
The Federation of New York State Bird Clubs’ annual midwinter
waterfowl count, or “Federation Waterfowl Count”
(FWC), was held during January 12-27, 2002 with approximately
270 participants. Weather conditions were mild but generally
unfavorable for complete counts due to extensive open water
and strong winds. Nonetheless, a record total of 447,867 birds
(46 species) was documented, 13% above the previous high (set
in 2001), and 67% above the 1973-2000 average. The top 10 species,
accounting for 85% of the total, were: Canada Goose, Mallard,
Greater Scaup, American Black Duck, Brant, Redhead, White-winged
Scoter, Common Goldeneye, Canvasback, and Surf Scoter. Canada
Geese accounted for most of the increase in total counts compared
to previous years.

INTRODUCTION
The Federation of New York State Bird Clubs has conducted an annual midwinter
waterfowl count (FWC) almost every year since 1955 (Rising 1955) except
for a brief hiatus in 1968-1972 (Jones 1980). Each January, members visit
lakes, rivers and shorelines throughout New York State to count waterfowl
(ducks, geese and swans) and associated water birds (e.g., loons, grebes,
cormorants and coot). Whenever possible, counts are conducted during a
9-day count period beginning on the first Saturday in January after New
Year’s Day, with a target date of the first Sunday in that period.
Most counts are conducted during the first 3 days, but in some cases additional
time is needed to complete the counts.
WEATHER
CONDITIONS
Official weather data for January 2002 were not available, but regional
compilers reported generally unfavorable conditions across the state.
Temperatures were mild, with highs in the 30s to low 40s, and overcast
skies and strong winds on the target date, especially on larger open water
areas, such as the Great Lakes shorelines. The count period was preceded
by a period of colder weather with little precipitation in January. Snow
cover from storms in December was largely gone from most areas during
the count period. As a result of this weather pattern, some smaller inland
waters were frozen, but all larger lakes and coastal bays remained entirely
open to waterfowl use.
RESULTS
A total of 447,867 birds, comprising 46 species, were counted in 2002
(Table 1). This established a new record high count
since the FWC began in 1955. The 2002 total was 13% above 2001(Table
2) and 67% above the 28-year (1973-2000) average of 268,763 (Table
3). Less than 1% of the total count was recorded outside of the scheduled
survey period.
Comparison of 2002 counts with 28-year (1973-2000) averages shows 7 of
13 major species or taxa at least 10% above average, and only two species
or taxa more than 10% below average (Table 3). Canada
Geese (211,191) shattered the previous high of 163,000 (in 2000), and
accounted for most of the increase in total counts compared to previous
years. New high counts were established also for Common Loon, Pied-billed
Grebe, White-fronted Goose, Tundra Swan, Gadwall, Northern Shoveler and
Ring-necked Duck. Relatively high counts of these and many other species
probably reflected the generally mild winter weather in 2001-2002. This
contrasted with the year before, when cold weather coincided with record
high counts of many diving duck species.
Total waterfowl numbers in the Atlantic Flyway (Maine to Florida) were
down 2% from 2001, and were 6% above the 10-year (1991-2000) average (Serie
and Raftovich 2002). Flyway counts of dabbling ducks were up 3% from a
year ago, diving ducks declined 11%, and sea ducks increased 55%. Canada
Goose counts in the flyway were unchanged from 2001 to 2002, whereas Brant
and Snow Goose counts increased 25% and 35%, respectively. Annual changes
in relative abundance in New York often do not mirror flyway trends because
state counts reflect distributional shifts (in response to weather) as
well as population changes.
Highlights of regional reports included a pair of Harlequin Ducks at
Buffalo (Region 1), a Barrow’s Goldeneye on the St. Lawrence River
near Ogdensburg (Region 6), the first-ever Brant on the FWC in Region
7 and a Great Cormorant on the Hudson River in Columbia County (Region
8).
FUTURE COUNTS
The FWC is especially important now that the New York State Department
of Environmental Conservation (DEC) has discontinued aerial surveys of
waterfowl wintering in New York. DEC concluded that the FWC provides comparable
or better data for monitoring long-term population trends (Swift and Hess
1999), so they now rely on the FWC as its standard survey. It is important
that member clubs and individuals maintain complete and consistent coverage
of areas surveyed in the past to ensure that results are comparable from
year-to-year and over the long-term.
For the planners among you, future counts are scheduled as follows:
2003 - January 11-19 (target date - Sunday, January 12)
2004 - January 10-18 (target date - Sunday, January 11)
2005 - January 9-17 (target date - Sunday, January 10)
