The U.S. Fish and Wildlife Service (FWS) released its preliminary
report today on breeding ducks and habitats, based on surveys conducted
in May and early June. Total populations were estimated at 48.6 million
breeding ducks in the surveyed area. This estimate represents a 7
percent increase over last year's estimate of 45.6 million birds, and is
43 percent above the 1955-2010 long-term average. This year's estimate
is a record high and is only the sixth time in the survey's history that
the total duck population exceeded 40 million.
"Early indications were that the mild and dry conditions experienced
across North America this past fall and winter would negatively impact
spring pond conditions and allow increases in grassland conversion
rates, ultimately impacting nesting efforts this season," said Ducks
Unlimited Chief Scientist Dale Humburg. "Strong returning duck
populations and late spring precipitation have brightened prospects for
2012 duck production. If nesting and brood-rearing conditions are
favorable over the next few months, we could see another strong fall
flight."
Of the 10 species traditionally reported, nine were similar to or
increased in number from 2011. Two species (northern pintail and
American wigeon) remained below their long-term average. Mallards, northern shovelers, blue-winged teal and scaup
were bright spots on this year's survey. For the first time since 1999,
mallard populations have exceeded 10 million. Northern shovelers and
bluewings again reached record highs (5.0 and 9.2 million,
respectively). Scaup numbers showed improvement and are above 5 million
for the first time since 1991. Scaup numbers showed improvement and are
above 5 million for the first time since 1991, but still remain below
the North American Waterfowl Management Plan (NAWMP) population goal.
Only three species—northern pintail, American wigeon and scaup—remain below NAWMP goals.
