SUMMARY
The New York State Ornithological Association (formerly Federation
of New York State Bird Clubs) annual January Waterfowl Count
(JWC), was held during January 10-19, 2004 with approximately
230 participants. Harsh winter weather prior to and during
the count resulted in many areas being frozen over and difficult
viewing conditions. Nonetheless, a total of 347,661 birds (47
species) were observed, 8% more than in 2003 and 24% above
the long-term (1973-2003) average. Total counts of ducks and
other water birds (loons, grebes, cormorants and coot) were
slightly below average, while total numbers of geese and swans
were well above average. The top 10 species, accounting for
88% of the total, were: Canada Goose, Mallard, Greater Scaup,
Redhead, Surf Scoter, American Black Duck, Brant, Common Merganser,
Common Goldeneye, and Bufflehead. Several notable regional
highlights were reported.

INTRODUCTION
The New York State Ornithological Association (formerly 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, participants 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 second Saturday 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 of the period, but in some cases
additional time is needed to complete the counts.
WEATHER
CONDITIONS
Official weather data for January 2004 were not obtained, but regional
compilers reported severe winter weather conditions just prior to and
during the count all across the state. As reported by Guthrie (2004): “There
was no doubt that the weather during 2003-04 winter season had an impact
on birds and birders. Many areas across the state experienced heavy snow
in December, followed by severe cold in January, when average temperatures
were in the range of 5-10 degrees below normal...The severe cold in January
resulted in little open water in most of the state, and , subsequently,
lower than normal waterfowl totals...” (except for geese and swans).
Regional compilers all reported that such conditions prevailed during
the count period, with temperatures well below freezing, occasional snow
fall, strong winds on many days, and extensive ice cover, making waterfowl
viewing difficult. As a result of this weather pattern, most small inland
waters and some larger bays and lakes were completely frozen. Many larger
lakes, rivers, and coastal bays had significant shoreline ice that limited
waterfowl use.
RESULTS
A total of 347,661, comprising 47 species, were counted in 2004 (Table
1). The 2003 total was 8% above 2003 and 24% above the long-term (1973-2003)
average of 280,376 birds (Table 2). Unfortunately, several important
areas on Long Island, accounting for approximately 13% of the total count,
were surveyed after the scheduled survey period, due to difficulties
finding volunteers to replace past observers who were unable to do the
counts this year.
Comparison of the 2004 counts with long-term (1973-2003) averages shows
10 of 21 major species or taxa at least 10% above average, and nine species
or taxa more than 10% below average (Table 2). Canada Geese (156,960)
climbed to the 3rd highest count ever, while most ducks, except Common
Eider and scoters, declined from a year ago. Counts of most other water
birds declined also, except for Double-crested Cormorant. A new high
count was established for Black Scoter (3,185).
Total waterfowl numbers in the Atlantic Flyway (Maine to Florida) were
up 2% from 2003, but were 7% below the 10-year (1994-2003) average (U.S.
Fish and Wildlife Service, unpublished data). Flyway counts of dabbling
ducks were up 9% from a year ago, diving ducks increased 22%, and sea
ducks decreased 21%. Flyway counts of Canada Geese and Brant declined
18% and 21%, respectively, whereas Snow Geese and Brant were up 37% from
a year ago. It appears that some of the decline in duck numbers in New
York were compensated for by increases in more southern states. Annual
changes in relative abundance in New York often do not mirror flyway
trends because state counts reflect effects of weather as well as population
changes.
Highlights of regional reports included a Northern Shoveler on the Niagara
River and a record number of Tundra Swans in Region 1, a Tufted Duck
on Lake Ontario (Region 2), two Barrow’s Goldeneye on Lake Champlain
(Region 7), White-fronted Geese in Dutchess County (Region 9), a Tundra
Swan on the lower Hudson River (Region 9), and a King Eider and 11 Harlequin
Ducks at Long Beach Island, contributing to a new high of 14 Harlequins
in Region 10 (Table 1). Numbers of Long-tailed Ducks in Region 1 increased
slightly from 2003 but were still below the numbers seen in recent years.
This decline may be due to the recent outbreak of Type E botulism in
that region, which has killed thousands of this species every fall since
2001.
FUTURE COUNTS
The JWC is a valuable long-term population monitoring program for waterfowl
and other water birds wintering in New York State. The Department of
Environmental Conservation (DEC) has discontinued aerial surveys of waterfowl
wintering in New York, so they now rely on the JWC as the 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. Future counts
are scheduled as follows:
2006 - January 14-22 (target date - Sunday, January 15); and
2007 - January 13-21 (target date - Sunday, January 14).
