Greater sage-grouse

The greater sage-grouse (Centrocercus urophasianus) is the largest grouse in North America. Before 2000, it was referred as simply the Sage-grouse. In that year, the Gunnison sage-grouse became a separate species.



Adults have a long, pointed tail and feathers on its toes. Adult males have a yellow patch above its eyes and a white breast. During courtship, the males two yellowish sacs inflate for display.
