Habitat

Dry grasslands with shrubs and short trees.

Range

Resident in southern Colorado and Kansas, south locally in western Oklahoma, Texas, and eastern New Mexico.

Discussion

The Lesser Prairie-Chicken likes short-grass prairies where stands of scrub oaks are common. Here males gather and engage in communal courtship displays in which the birds dance about with the colorful air sacs on their necks inflated, uttering low cooing or "booming" notes. This species replaces the Greater Prairie-Chicken in higher, drier grasslands.

Nesting

11-13 creamy or buff-colored eggs in a grass-lined depression, usually under a low bush or shrub.
