American Black Duck

Anas rubripes

Appearing at first glance like a female mallard, this monomorphic species is found primarily on the eastern half of North America. They like to flock with mallards and sometimes even breed together, producing hybrids with subtle characteristics of both species. To separate out this species, take note of the greater contrast between the lighter head and darker body, and the deep blue speculum that has no white border.

Primarily inhabiting the eastern parts of North America, these ducks can be spotted year round in Rhode Island, but they are also found in the upper reaches of Quebec and Newfoundland during the breeding season. In the colder months, especially around late fall and early winter, large flocks gather near the banks of the Seekonk River, numbering in the hundreds.
