This list of birds of Hawaii is a comprehensive listing of all the bird species seen naturally in the U.S. state of Hawaii as determined by Robert L. and Peter Pyle of the Bishop Museum, Honolulu. The scope of this list encompasses the entire Hawaiian Islands chain, from Kure Atoll in the Northwestern Hawaiian Islands to the north, to the "Big Island" of Hawaii to the south. The list contains 338 species. Of them, 64 are or were endemic to the islands, 130 are vagrants and 53 were introduced by humans. Thirty-three of the 64 endemic species are extinct and two formerly established introduced species were extirpated. The list does not include introduced species that have not become established.
