Image# M036 - Male Rheas
Male rheas court a 'harem of hens' by displaying their wings. A male will walk behind a group of femals and steer them towards his nest, where he will encourage them to lay their eggs. Male rheas will also fight for dominancy by locking their beaks together and pushing and shoving each other with chests. The winning male gets to mate with the females. During breeding season, the males will fight several times a day.
