Frigatebirds: Fregatidae

The Ascension frigatebird is listed as Critically Endangered, facing an extremely high risk of extinction, and the Christmas frigatebird is considered Vulnerable, facing a high risk of extinction. Both lost much of their habitat when people developed the islands where they breed, and they do not like to be disturbed by people who come to watch and photograph them close-up. But their biggest trouble is the variety of mammals brought to the islands by people. Rats, pigs, goats, and pet cats eat the frigatebirds' eggs and chicks, and they destroy the plants the birds need in breeding areas.
