In the spring, during their breeding season, male sage-grouse gather to do their courtship displays. They do this on areas called "leks". As the males dance they make a popping sound. This is done by inflating and deflating their two yellow throat sacs. They display their pointed tail feathers while they strut. As many as a dozen males may dance at the same time. Sometimes two males will fight with their wings. The hens will watch for several days before picking out a mate. They make their nests in the sagebrush. The males do not help with nesting or with raising chicks.
