Anas sp.—Dabbling DucksRegional Pleistocene distribution of Anas sp.

Anas is a huge genus whose presence implies only that some standing water, temporary or permanent, was in the vicinity. The species noted below occur today throughout watered parts of the region as wintering and/or breeding populations or in migration. None is important as an environmental marker and individual accounts are not given.
