Flicker, a large woodpecker native to North America. Unlike most other woodpeckers, flickers are often seen on the ground, where they feed on ants. Flickers usually nest in holes made in trees by themselves or other woodpeckers. Both parents incubate the eggs, and both feed the young.
The yellow-shafted flicker or yellowhammer ranges chiefly east of the Rockies. The red-shafted flicker is found chiefly west of the mountains. Both grow as much as 13 inches (33 cm) long. The birds are brownish, marked with black spots and bars and with a black crescent on the breast. The yellow-shafted flicker is yellow under the wings and tail, and the male has a band of black, resembling a mustache, near the bill. The red-shafted flicker is reddish under the wings and tail, and the male has red mustache markings.
Flickers belong to the woodpecker family, Picidae. The yellow-shafted is Colaptes auratus auratus; red-shafted, C. a. cafer.The red-shafted flicker is marked with black spots and a black crescent on the breast.
