The recurve-billed bushbird (''Clytoctantes alixii'') is a Thamnophilid antbird that inhabits dense stands of secondary vegetation at the northern end of the Andes in Colombia and Venezuela. It is named for its extraordinary bill, which curves upwards. Until 2007, the bird was almost unknown in life and apart from earlier specimens it had only been seen in life once at an army ant swarm in Colombia in 1965. ==Discovery and rediscovery== The species was first described in 1870 by Daniel Giraud Elliot from a specimen obtained from the Rio Napo. He named the species after Dr. Edouard Alix (1823–1893) of Paris. A significant effort in Colombia failed to find the bird. However, in April 2004 the species was found in Venezuela in the foothills of Sierra de Perijá close to the border with Colombia, during a Conservation International-financed Rapid Assessment (RAP) expedition consisting of ornithologists Miguel Lentino, Jorge Perez-Eman, Irving Carreño and Chris Sharpe working under the auspices of the Venezuela Audubon Society and the Phelps Ornithological Collection. The first photographs were taken of a pair of birds. Four months later the first sound recordings were made and behavioral notes taken by British ornithologist Chris Sharpe. Working in parallel, Colombian ornithology student Oscar Laverde rediscovered bushbirds in Norte de Santander, Colombia in July 2005. The birds were subsequently studied in detail by Laverde, F. Gary Stiles and ornithology students of the Natural Sciences Institute of the National University of Colombia. Their findings are published in issue No. 5 of Ornitología Colombiana. They are better located using their call which is made up of four short whistling notes. The first published photos of the species were circulated by the in June 2007 from images taken by Fundacion ProAves at a new reserve in Colombia to protect this species. 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「Recurve-billed bushbird」の詳細全文を読む スポンサード リンク
