Umbrellabird is any one of a group of birds known for the umbrellalike crest of feathers that spread over the head of males. Umbrellabirds live in the tropical forests of Central and South America. Males also have a growth of skin, called a wattle, that hangs down from the neck. In some species (kinds) of umbrellabirds, the wattle is covered with feathers. Male umbrellabirds display the crest and wattle to attract a mate. Both the crest and the wattle are less developed in females. An umbrellabird is about the size of a crow and has black feathers.
