Sage Grouse Relies On Their Air Sac
Canadian sage grouse gather in the Canadian Prairies every year to engage in competitive mating rituals. Every morning, they puff out air sacs in their chests, swing their tails, and make sounds, in the hopes they’ll attract females who gather around them to watch. After the performance, the female chooses the one she thinks is the best. Most females will choose the most dominant male. Some call this the best mating dance in the West (WLFW).
