Breeding biology and habitat use of black ducks

Forested wetlands are Important habitats for black ducks nesting in the Northeast. Invertebrates, with their high protein content, are primary foods of females during egg laying and for rapidly growing ducklings. Beaver-created and modified wetlands provide excellent habitat for feeding as well as protective cover. As these wetlands age, their quality declines after 7-10 years, and waterfowl use diminishes. Wetland availability and quality should be considered when managing beaver.
