Woodcreepers (Dendrocolaptidae)

Long-billed Woodcreeper (Nasica longirostris) - HBW 8, p. 411

French: Grimpar nasican German: Elfenbeinschnabel-Baumsteiger Spanish: Trepatroncos Piquilargo

Taxonomy: Dendrocopus longirostris Vieillot, 1818, Boca do Igarapé Piaba, near Obidos, Pará, Brazil.
May be ancestral to all Dendrocolaptidae with exception of Drymornis. Birds from localities S of R Amazon having paler upperparts and more tawny underparts sometimes separated as race australis, but differences appear to be attributable to individual variation; by contrast, birds from S bank have significantly longer bill than those from N bank, suggesting that recognition of two races may be warranted; further study needed. Monotypic.

Distribution: Amazonia & R Orinoco from E Colombia and S Venezuela S to C Ecuador, NC & E Peru, Amazonian Brazil (E to C Roraima, Amapá and Maranhão, S to N Mato Grosso and S Tocantins) and N Bolivia; apparently absent from Guianan shield with exception of C & E French Guiana.
