The white-rumped falcon (''Polihierax insignis'') is a species of bird of prey in the family Falconidae native to Indochina. It is sometimes placed in its own monotypic genus, ''Neohierax''. ==Taxonomy and naming== Philip Sclater, secretary of the Zoological Society of London, presented two skins at the meeting of 7 November 1871, on behalf of the society's president Arthur Hay, Viscount Walden. A brief account of this presentation was published in 1872, becoming the first formal description of the species.〔〔 In 1922, Harry Kirke Swann proposed a new monotypic genus for this bird, ''Neohierax''.〔〔 During the 20th century, most taxonomic authorities retained it in ''Polyhierax'', though Brown and Amadon supported separating the two genera. Phylogenetic analyses of morphological characteristics found the white-rumped falcon to be basal to the ''Falco'' clade, but separate from the clade containing the pygmy falcon (or African pigmy falcon, ''Polihierax semitorquatus'') and ''Microhierax'' (falconets or pigmy falcons).〔 Research in molecular genetics〔 has also found that the white-rumped falcon is more closely related to the ''Falco'' falcons than it is to the pygmy falcon, and indicates two major clades within the extant members of the falcon subfamily, Falconinae. Boyd places the ''Microhierax'' falconets with the pygmy falcon in tribe Polihieracini, and the white-rumped falcon as ''Neohierax insignis'' in tribe Falconini.〔 The white-rumped falcon is also known as white-rumped pygmy falcon, white-rumped falconet, Fielden's falconet,〔 or Burmese pigmy falcon.〔 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「White-rumped falcon」の詳細全文を読む スポンサード リンク
