The Greater Sage-Grouse is a large grouse with a chubby, round body, small head, and long tail. Males change shape dramatically when they display, becoming almost spherical as they puff up their chest, droop their wings, and fan their tail into a starburst.

In courtship display, male puffs out white chest, inflates two yellow air sacs, raises and spreads tail, droops wings; head is thrown back on shoulders as air sacs are deflated with loud popping sound. Females visit display ground to mate with one of the males. Oldest and most experienced males compete for positions at center of display ground, and these males are usually chosen by females
