Burung mirip Mallard

Key differences

Mallards have a green head (male) or mottled brown head with a distinct eye-stripe (female), and an orange bill. American Black Ducks are uniformly dark brown with a paler head, a dark bill, and a purplish speculum (not blue) that is less distinctly bordered by white.

Key differences

Mottled Ducks are similar to female Mallards but are generally darker overall, lack the distinct eye-stripe, and have a more uniformly yellow-orange bill (females) or yellow bill (males) without dark mottling. Their speculum is blue-green, often without prominent white borders.

Key differences

Often considered a subspecies of Mallard (Anas platyrhynchos diazi). It resembles a female Mallard but is generally darker, with a less distinct eye-stripe and a more uniformly yellow bill. Its speculum is blue-green with less prominent white borders.
