In a few species, including phalaropes, painted snipes, and rheas, the males incubate the eggs and take care of the young. Phalarope plumage colors are reversed from the usual pattern, males are drably colored and females are brightly colored. Sage Grouse gather in large groups at traditional breeding grounds called leks where the males display communally to attract a female. In the early morning, the males meet on an arena and strut around with their feathers erect and air sacs on their chests inflated. The females select a male from the group, mate with him, and they fly off to nest and rear the young alone.
Many birds perform elaborate courtship dances.
Cranes are the most accomplished dancers in the bird world and their courtship dances include bowing, jumping up and down, and flapping their wings.
