43 cm. Stocky, uniformly barred brown grouse. Almost entire brown plumage barred with paler stripes. Both sexes have obvious dark eye-stripe and pale throats. Both also show elongated pinnae (adapted neck feathers) - the males being especially long and erected over the head during display, at which time yellow air sacs in the neck and above the eye are inflated. Similar species Range does not overlap with Lesser Prairie-chicken which has a diagnostic reddish-purple neck sac. Hint Watch for displaying males at dawn from discrete distance at known leks.
