The black-necked grebe (''Podiceps nigricollis''), known in North America as the eared grebe, is a member of the grebe family of water birds. It occurs on every continent except Australia and Antarctica. ==Taxonomy== There are three subspecies:〔Ogilvie & Rose (2003), p. 69.〕 * ''P. n. nigricollis'' – (Brehm, CL, 1831): nominate, is found from western Europe to western Asia (wintering to the south and west), in central and eastern Asia, and in eastern Africa * ''P. n. gurneyi'' – (Roberts, 1919): is found in southern Africa * ''P. n. californicus'' – (Heermann, 1854): is found from southwestern Canada through the western U.S. It winters as far south as Guatemala. Both common names for this species refer to features visible when the bird is in its breeding plumage; in such plumage, it has an all-black neck and a spray of golden plumes on each side of its head. The name "eared grebe" was in use nearly a century before the name "black-necked grebe". The latter was first used in 1912 by Ernst Hartert, in an effort to bring the common name of the species in line with its scientific name.〔Ogilvie & Rose (2003), pp. 102–103.〕 The genus name of this species—''Podiceps''—comes from two Latin words: ''podicis'', meaning "vent" or "anus" and ''pes'' meaning "foot".〔Ogilvie & Rose (2003), p. 98.〕 This is a reference to the attachment point of the bird's legs—at the extreme back end of its body. The specific epithet ''nigricollis'' is Latin for "black-necked": ''niger'' means "black" and ''collis'' means "neck". 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「Black-necked grebe」の詳細全文を読む スポンサード リンク
