The Brown-headed Cowbird is a common bird of the Great Plains who has expanded its range Westward and Eastward. This bird is often found in flocks foraging for the insects and grains on which it feeds. The Brown-headed Cowbird got its name from its coloration as well as its habits. In the past, this bird followed groups of bison around to catch the insects that the bison herd threw up with their hooves. During breeding season, the female lays her eggs in the nests of other birds leaving them to care for her young. The problem with this is that the Cowbird eggs hatch sooner and the young grown faster than the other bird's eggs and young so the other chicks often die. This bird is common in woodland and open landscapes.
The female is brown in overall coloration rather than the male with is black other than the head.
The juvenile Brown-headed Cowbird is brown everywhere.
