Witness the elaborate courtship display of the greater sage-Grouse in this video from NATURE: The Sagebrush Sea. During the breeding season, greater sage-grouse males forms leks, groups where the birds compete for the attention of females. The males inflate pouches in their necks and fan their feathers. Females select certain males to mate with.
