Understanding duck food preferences is important when managing impoundments and wetlands to attract migratory ducks. Dabbling ducks and wood ducks are the focus of most duck hunters and duck habitat managers in southern Oklahoma and northern Texas. Dabbling duck species include mallard, gadwall, American wigeon, northern pintail, northern shoveler, three teal species (green-winged, blue-winged and cinnamon) and a few other less common species. Diving ducks such as canvasback, redhead, ring-necked duck and lesser scaup tend to receive less management focus in Oklahoma and Texas.
