The swallow-tailed cotinga (''Phibalura flavirostris'') is a species of passerine bird. As suggested by its common name, it has traditionally been considered a member of the cotinga family. Following the recent removal of several members from this family (now placed in Tityridae), the placement of this aberrant species is unclear. It is therefore considered ''incertae sedis'' by SACC.〔Remsen, J. V., Jr., C. D. Cadena, A. Jaramillo, M. Nores, J. F. Pacheco, M. B. Robbins, T. S. Schulenberg, F. G. Stiles, D. F. Stotz, & K. J. Zimmer. 2007. (''A classification of the bird species of South America.'' ) American Ornithologists' Union. Accessed 12 December 2007.〕 Currently, it is monotypic within the genus ''Phibalura'',〔http://www.worldbirdnames.org/n-flycatchers.html〕 but it has been suggested that the taxon ''boliviana'' should be considered a separate species, the Bolivian swallow-tailed cotinga or Palkachupa cotinga (''P. boliviana''). The nominate taxon (''P. f. flavirostris'') is found in Atlantic forest in south-eastern Brazil, eastern Paraguay and Argentina (Misiones only). The taxon ''boliviana'', which only was rediscovered in 2000 (after 98 years without any records), is restricted to the vicinity of Apolo in Bolivia. Both populations are threatened by habitat loss. ==References== == External links == *(Photo ); (Article ) tropicalbirding *(Swallow-tailed Cotinga photo gallery ) VIREO 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「Swallow-tailed cotinga」の詳細全文を読む スポンサード リンク
