The frigate birds are a family of seabirds and are also called frigate pelicans. It can be found breeding along the Pacific coast of Costa Rica and in the Corcovado National Park.
They have long wings, tails and bills and the males have a red pouch that is inflated during the breeding season to attract a mate. Females are black, but have a white breast and lower neck sides, a brown band on the wings and a blue eye ring. The Frigate bird is 1m long with a 2.15m wingspan.
They lack the ability to take off from water so they snatch prey from the ocean surface or beach using their long, hooked bills. Frigate birds are seasonally monogamous which means they only mate with one female per season. They also nest as a colony. They lay one or two white eggs. Both parents take turns feeding for the first three months but then only the mother feeds the young for another eight months.
