Fewer wintering waterfowl counted in Maryland in 2011

Scientists observed more than 640,000 ducks, geese and swans along Maryland’s Chesapeake Bay shoreline this winter as part of the U.S. Fish & Wildlife Service and Maryland Department of Natural Resources’ annual Midwinter Waterfowl Survey. This is a decline from 2010, when approximately 787,000 waterfowl were counted.

The decline is largely due to fewer Canada geese and snow geese being counted for the survey. Large numbers of geese likely went undetected because they were on farms and other inland habitats. Overall, the wintering Canada geese remained high.

More ducks were counted in 2011 (199,300) than in 2010 (173,700) due to snow and cold weather north of Maryland, according to DNR. In particular, there were more mallards and canvasbacks, as well as an exceptional number of gadwalls on the Susquehanna Flats.

The Midwinter Waterfowl Survey has been conducted annually throughout the United States since the early 1950s. Maryland survey results are ultimately pooled with results from other states to measure wintering waterfowl distribution and populations throughout the Atlantic Flyway, according to DNR Waterfowl Project Leader Larry Hindman.

“The survey is conducted in a coordinated manner across the Atlantic Flyway states to provide an annual index of the population size for important waterfowl species like black ducks, Atlantic brant and tundra swans,” Hindman said.
