There are 71 known taxa of birds endemic to the Hawaiian Islands, of which 30 are extinct, 6 possibly extinct and 30 of the remaining 48 species and subspecies are listed as endangered or threatened by the United States Fish and Wildlife Service. In the era following western contact, habitat loss and avian disease are thought to have had the greatest effect on endemic bird species in Hawaii, although native peoples are implicated in the loss of dozens of species before the arrival of Captain Cook and others, in large part due to the arrival of the Polynesian rat (Rattus exulans) which came along with the first Polynesians.
