American Black Duck Wintering Dynamics And Dabbling Duck Response To Herbicide Application In Western Tennessee Wetlands, Joshua Matthew Osborn

Masters Theses

American black duck (Anas rubripes) populations declined throughout North America in the late 20^th century. Although the breeding population has since stabilized, research investigating habitat use by black ducks in the Mississippi Flyway is scarce. Impacts of wetland management practices in response to invasive species must also be tested to measure responses to habitat quality by black ducks and other waterfowl. During winters 2011-2013 (December-February), I estimated food biomass, diurnal habitat use, and activities of black ducks in 6 cover types at the Duck River Unit of Tennessee National Wildlife Refuge and Cross Creeks National Wildlife Refuge …
