This list of birds of Connecticut is a comprehensive listing of all the bird species recorded from the U.S. state of Connecticut. This list is based on a checklist used by the Avian Records Committee of Connecticut, the list used by most birders to objectively evaluate species recorded in the state. This list is based on the committee's revision from 2007.〔(【引用サイトリンク】work=Connecticut Ornithological Association )〕 A total of 417 species of birds have been recorded in Connecticut.〔 This number includes all bird species known to have occurred in the state, including birds that don't breed in Connecticut, such as migrants, winter visitors and vagrants, as well as breeding species and recently extinct and extirpated species. There are about 280 species regularly occurring in the state. ''The Atlas of Breeding Birds of Connecticut'' (1994) listed 173 bird species as confirmed breeders, based on a 1982–1986 survey. An assessment before 2004 estimated the total number of species breeding regularly in the state at about 150.〔Hammerson, Geoffrey A., ''Connecticut Wildlife: Biodiversity, Natural History, and Conservation'', University Press of New England: Hanover, New Hampshire, and London, 2004, ISBN 1-58465-369-8, Chapter 20 "Birds"〕 The taxonomic treatment (designation and sequence of orders, families, genera and species) and nomenclature (common and scientific names) used in the accompanying bird lists adhere to the conventions of the AOU's (1998) ''Check-list of North American Birds'', the recognized scientific authority on the taxonomy and nomenclature of North American birds. The AOU's Committee on Classification and Nomenclature, the body responsible for maintaining and updating the ''Check-list'', "strongly and unanimously continues to endorse the biological species concept (BSC), in which species are considered to be genetically cohesive groups of populations that are reproductively isolated from other such groups" (AOU 1998). See Sibley-Ahlquist taxonomy for an alternative phylogenetic arrangement based on DNA-DNA hybridization. The following codes are used to designate some species: * (I) Introduced - a species introduced to North America as a consequence, direct or indirect, of human actions * (X) Extinct - a species that no longer exists * (E) Extirpated - a species that no longer occurs in Connecticut although populations exist elsewhere * (S) - sight record only __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. *Ross's goose, ''Chen rossii'' (R) *Brant, ''Branta bernicla'' *Barnacle goose, ''Branta leucopsis'' (R) *Cackling goose, ''Branta hutchinsii'' *Canada goose, ''Branta canadensis'' *Mute swan, ''Cygnus olor'' (I) *Wood duck, ''Aix sponsa'' *Gadwall, ''Anas strepera'' *Eurasian wigeon, ''Anas penelope'' *American wigeon, ''Anas americana'' *American black duck, ''Anas rubripes'' *Mallard, ''Anas platyrhynchos'' *Blue-winged teal, ''Anas discors'' *Cinnamon teal, ''Anas cyanoptera'' (R) *Northern shoveler, ''Anas clypeata'' *Northern pintail, ''Anas acuta'' *Green-winged teal, ''Anas crecca'' *Canvasback, ''Aythya valisineria'' *Redhead, ''Aythya americana'' *Ring-necked duck, ''Aythya collaris'' *Tufted duck, ''Aythya fuligula'' (R) *Greater scaup, ''Aythya marila'' *Lesser scaup, ''Aythya affinis'' *King eider, ''Somateria spectabilis'' *Common eider, ''Somateria mollissima'' *Harlequin duck, ''Histrionicus histrionicus'' *Surf scoter, ''Melanitta perspicillata'' *White-winged scoter, ''Melanitta fusca'' *Black scoter, ''Melanitta americana'' *Long-tailed duck, ''Clangula hyemalis'' *Bufflehead, ''Bucephala albeola'' *Labrador duck, ''Camptorhynchus labradorius'' (X) *Barrow's goldeneye, ''Bucephala islandica'' *Common goldeneye, ''Bucephala clangula'' *Hooded merganser, ''Lophodytes cucullatus'' *Common merganser, ''Mergus merganser'' *Red-breasted merganser, ''Mergus serrator'' *Ruddy duck, ''Oxyura jamaicensis'' 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 Connecticut」の詳細全文を読む スポンサード リンク
