We correct the limits of the range and analyse the geographical variation of the Moustached Woodcreeper Xiphocolaptes falcirostris, an endemic species of north-eastern Brazil. A single, undated specimen of Moustached Woodcreeper from Posse, Goiás, in the Parana River Valley was probably collected somewhere on the left bank of the São Francisco River. Analysis of the plumage variation and five body measurements indicates that it is not always possible to separate the populations of the Moustached Woodcreeper into the two subspecies currently recognized. In spite of this, given the importance of this bird as an indicator species for conservation, we suggest that the current recognition of the subspecies be maintained until generic studies provide a definitive answer to this taxonomic question. Moustached Woodcreepers are particularly associated with patches of dry forest growing on rich soils in north-eastern Brazil. In the past decades, this type of vegetation has been drastically modified by human activities. Only an urgent plan to establish a network of reserves for tropical dry forests in north-eastern Brazil can prevent the complete destruction of this habitat and of its poorly known biological resources.
