It’s confirmed. Ducks are getting into new rows. More specifically, U.S. Geological Survey (USGS) U.S. Fish and Wildlife Service and Ducks Unlimited scientists found that over the last 60 years, the autumn and winter ranges of three species of dabbling ducks have shifted.
Before you ask, no, the scientists don’t yet know why. But they are already looking into it.
Importantly, the autumn and winter ranges of the mallard, northern pintail, and blue-winged teal are different, but scientists did not find evidence of wholesale abandonment of large wintering regions or switching between flyways. This research used 60 years of bird band data contributed by waterfowl hunters in one of the longest-term community science efforts in North America.
“This research was in direct response to public concern that duck winter ranges had shifted northward,” said Lisa Webb, Southern Regional Supervisor for the USGS Cooperative Research Units Program and study co-author. “It was made possible by over half a century of work and investment by numerous waterfowl banders and supporting agencies in the United States and Canada.”
