Sharp-tailed Grouse

Males perform their unique dance, rapidly stomping their feet, and vocalizing, with wings spread, and purple neck sacs inflated, challenging each other, usually in pairs. Eventually, a female arrives and walks around nonchalantly, which sets off a frenzied performance by the males. After a thorough inspection, she selects a male and copulation takes. place. This, her only visit to the lek, will fertilize her entire clutch of up to a dozen eggs.
