Tschudi's woodcreeper
Tschudi's woodcreeper, ''Xiphorhynchus ocellatus chunchotambo'', is a passerine bird native to South America. It belongs to the genus ''Xiphorhynchus'' in the woodcreeper subfamily, Dendrocolaptinae. It is usually regarded as a subspecies of the ocellated woodcreeper (''X. ocellatus''). It is named after Johann Jakob von Tschudi, the Swiss explorer and naturalist who first described the bird.
==Taxonomy==
It was initially described as a species by Johann Jakob von Tschudi in 1844. He named it ''Dendrocolaptes Chunchotambo'' but it was later moved to the genus ''Xiphorhynchus''. It was later lumped into the ocellated woodcreeper (''X. ocellatus'') but Aleixo (2002) recommended splitting the species based on a study of mitochondrial DNA which showed that the ocellated woodcreeper was more closely related to the chestnut-rumped woodcreeper (''X. pardalotus'') than to Tschudi's woodcreeper.〔Aleixo, Alexandre (2002) (Molecular systematics and the role of the "Várzea"-"Terra-firme" ecotone in the diversification of ''Xiphorhynchus'' woodcreepers (Aves: Dendrocolaptidae). ) ''Auk'', 119 (3): 621-640.〕 The South American Committee of the AOU have yet to recognize the split however.
There are two or three subspecies of Tschudi's woodcreeper group: ''X. o. chunchotambo'', ''X. o. brevirostris'' and perhaps ''X. o. napensis''.
