The bird genus ''Hirundo'' is a group of passerines in the family Hirundinidae (swallows and martins). These are the typical swallows, including the widespread barn swallow. Many of this group have blue backs, red on the face and sometimes the rump or nape, and whitish or rufous underparts. With fourteen species this genus is the largest in its family. All of the species are found in the Old World, although one, the barn swallow, is cosmopolitan, also occurring in the Americas. Genetic evidence has recently shown that many of the species previously included in ''Hirundo'' are less closely related than their appearance might suggest; these species are sometimes treated in the separate genera ''Cecropis'' (e.g. red-rumped swallow ''Cecropis daurica'', previously ''Hirundo daurica'') and ''Petrochelidon'' (e.g. cliff swallow ''Petrochelidon pyrrhonota'', previously ''Hirundo pyrrhonota''); they are as distinct from typical ''Hirundo'' as the house martins in the genus ''Delichon''. ==Species== *Barn swallow ''Hirundo rustica'' *Red-chested swallow ''Hirundo lucida'' *Angolan swallow ''Hirundo angolensis'' *Pacific swallow ''Hirundo tahitica'' *Hill swallow ''Hirundo domicola'' *Welcome swallow ''Hirundo neoxena'' *White-throated swallow ''Hirundo albigularis'' *Ethiopian swallow ''Hirundo aethiopica'' *Wire-tailed swallow ''Hirundo smithii'' *White-bibbed swallow ''Hirundo nigrita'' *Pied-winged swallow ''Hirundo leucosoma'' *White-tailed swallow ''Hirundo megaensis'' *Pearl-breasted swallow ''Hirundo dimidiata'' *Blue swallow ''Hirundo atrocaerulea'' *Black-and-rufous swallow ''Hirundo nigrorufa'' 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「Hirundo」の詳細全文を読む スポンサード リンク
