With their distinctive angular, pointed wings and long, scissor-shaped tails, the frigatebirds are perhaps the most recognizable of all seabirds. The male lesser frigatebird is all black, except for a white patch under the wings that extends onto the side of the breast. They have a glossy blue, purple and green sheen to the feathers of the head, neck and upper back region, and, like other male frigatebirds, possess a large, red pouch that is blown up like a balloon during displays to attract a mate. The female is larger than the male, has a less glossy sheen to the black feathers, has a pouch that is not distensible and a white upper breast contrasting with a black throat, with the white extending onto the sides. The juvenile has a reddish-brown head and upper neck and white undersides, and displays a number of immature plumages before eventually taking on that of the adult.
