Comparative productivity of American black ducks and mallards nesting on Chesapeake Bay islands
View through CrossRef
We estimated laying dates, clutch sizes, and nest success rates of sympatrically breeding populations of American black ducks (Anas rubripes) and mallards (Anas platyrhynchos) on Chesapeake Bay islands between 1986 and 1989. Neither average laying date nor clutch size differed between black ducks and mallards. Nest success rates were higher for mallards in 2 of 4 years, but were area dependent.

Description:
We estimated laying dates, clutch sizes, and nest success rates of sympatrically breeding populations of American black ducks (Anas rubripes) and mallards (Anas platyrhynchos) on Chesapeake Bay islands between 1986 and 1989.
Neither average laying date nor clutch size differed between black ducks and mallards.
Nest success rates were higher for mallards in 2 of 4 years, but were area dependent.
