Pale grayish-brown chickenlike bird, found in open spaces with mix of grasses and shrubs. Often on the ground or perched high in trees. Look for whitish tail with pointed tip, slight crest, wings spotted with white, and sparsely marked pale belly. In early spring, males gather at display site and dance to attract females: look for tail cocked up, wings held out, and purple patch of exposed skin on neck. Sexes alike. Most similar to prairie-chickens but note paler belly and pointed tail.
