This is a long-term, multi-faceted and multi-species study, investigating survival, habitat use and movements of wintering female dabbling ducks, and has regional and international components. The study was initiated on Northern Pintails and has focused on Mallards and Gadwall during the last 5 years. The overall goal of the study is to provide information useful for winter habitat and refuge management by states and Joint Ventures within the region. The Mallard studies employed VHF transmitters and provided data on birds wintering in TX, LA, AR, and MS, whereas the Gadwall study has both regional (LA, TX) and international components, given an additional objective of documenting spring migration corridors and breeding areas within the northern U.S. and Canada using satellite transmitters. Dr. Afton is the PI and lead 3 different teams of 1 M.S. student and 2-3 technicians each, capturing Mallards in southwest and northeast Louisiana and Gadwalls in southwest LA. The Mallard and Gadwall studies were funded by Ducks Unlimited, USFWS Region 2 through the Gulf Coast Joint Venture, Texas Parks and Wildlife, and Louisiana Department of Wildlife and Fisheries.
