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 the Hawaiian Audubon Society. This list is based on Robert Pyle's revision dated March 31, 2005. 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 following codes define the distribution and relative abundance of species on this list: * (A) Accidental - occurrence based on a few records, and unlikely to occur regularly * ( *) Endemic - a species either entirely confined to the Hawaiian Islands in its natural distribution, or a species whose breeding range is entirely confined to the Hawaiian Islands * (ex) Extirpated - a species that no longer occurs in Hawaii, but other populations still exist elsewhere * (I) Introduced - population established solely as result of direct or indirect human intervention; synonymous with non-native and non-indigenous This list is presented in taxonomic order. The family accounts at the beginning of each heading reflect this taxonomy, as do the species counts found in each family account. __NOTOC__ ==Ducks, geese and swans== Order: AnseriformesFamily: Anatidae The family Anatidae includes the ducks and most duck-like waterfowl, such as geese and swans. These birds are adapted to an aquatic existence with webbed feet, bills which are flattened to a greater or lesser extent, and feathers that are excellent at shedding water due to special oils. *Fulvous whistling duck, ''Dendrocygna bicolor'' (ex) *Greater white-fronted goose, ''Anser albifrons'' (A) *Emperor goose, ''Chen canagica'' (A) *Snow goose, ''Chen caerulescens'' (A) *Canada goose, ''Branta canadensis'' *Cackling goose, ''Branta hutchinsii'' *Nene, ''Branta sandvicensis'' ( *) *Brant, ''Branta bernicla'' *Tundra swan, ''Cygnus columbianus'' (A) *Gadwall, ''Anas strepera'' (A) *Falcated duck, ''Anas falcata'' (A) *Eurasian wigeon, ''Anas penelope'' *American wigeon, ''Anas americana'' *Mallard, ''Anas platyrhynchos'' (I) *Hawaiian duck, ''Anas wyvilliana'' ( *) *Laysan duck, ''Anas laysanensis'' ( *) *Baikal teal, ''Anas formosa'' (A) *Blue-winged teal, ''Anas discors'' *Cinnamon teal, ''Anas cyanoptera'' (A) *Northern shoveler, ''Anas clypeata'' *Northern pintail, ''Anas acuta'' *Garganey, ''Anas querquedula'' *Green-winged teal, ''Anas crecca'' *Canvasback, ''Aythya valisineria'' (A) *Redhead, ''Aythya americana'' (A) *Common pochard, ''Aythya ferina'' (A) *Ring-necked duck, ''Aythya collaris'' *Tufted duck, ''Aythya fuligula'' (A) *Greater scaup, ''Aythya marila'' *Lesser scaup, ''Aythya affinis'' *Harlequin duck, ''Histrionicus histrionicus'' (A) *Surf scoter, ''Melanitta perspicillata'' (A) *Black scoter, ''Melanitta americana'' (A) *Long-tailed duck, ''Clangula hyemalis'' (A) *Bufflehead, ''Bucephala albeola'' *Common goldeneye, ''Bucephala clangula'' (A) *Barrow's goldeneye, ''Bucephala islandica'' (A) *Hooded merganser, ''Lophodytes cucullatus'' (A) *Common merganser, ''Mergus merganser'' (A) *Red-breasted merganser, ''Mergus serrator'' (A) *Ruddy duck, ''Oxyura jamaicensis'' (A) *Black swan, ''Cygnus atratus'' (I) 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「List of birds of Hawaii」の詳細全文を読む スポンサード リンク
