General Information

The Greater Sage-Grouse is a large grouse with a chunky, 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. Sage-Grouse are mottled gray-brown with a black belly. Males have a black head and throat. The breast has a fluffy white ruff that, during displays, surrounds a pair of inflatable, yellow air sacs. Females have a dusky cheek patch emphasized by white markings behind the eye.
