Yellow-billed Pintail
Anas georgica
The yellow-billed pintail has a brown head and neck. The bill is yellow with a black tip and a black stripe down the middle. The tail is brownish and pointed. The upper wing is grayish-brown, and the secondaries are blackish-green. The rest of the body is buffish brown with varying-sized black spots. The species is sometimes confused with yellow-billed teal (Anas flavirostris) but can be differentiated by the yellow stripes on its bill, its larger size, and its tendency not to form large groups. The nominate subspecies is smaller and darker than Anas g. spinicauda.
