General Description: American Black Ducks (Anas rubripes) are large puddle ducks that look similar to female Mallards (Anas platyrhynchos), often occurring in mixed flocks. On careful inspection, Black Ducks are darker overall with reddish flanks and a yellowish bill.

Taxonomy: Anseriformes, Anatidae, Anatinae

Favored Habitat: Ponds and marshes.

Where to Find: Don't look for Black Ducks around Las Vegas. Rather, look for them in eastern Canada during the breeding season, and the eastern US during winter.

Comments: Black Ducks have been mating with Mallards to the detriment of the Black Duck species. Black Duck genes are being swamped out, but management has helped stabilize their populations.
