Habitat Selection and Survival of American Black Ducks in Western Tennessee
The American black duck (Anas rubripes) has been declining throughout its range since the 1950s, especially in the Mississippi Flyway. Loss of quality wintering habitat and competition and hybridization with mallards (A. platyrhynchos) have been suggested as factors contributing to black duck decline. Tennessee and Cross Creeks National Wildlife Refuges (NWRs) are two primary wintering areas for midcontinent black ducks recording long-term population declines. To better understand habitat selection and habitat-related survival of black ducks at Tennessee NWR (TNWR), we radio marked 64...
