See text Dendrocolaptes guttatusLichtenstein, 1820 The buff-throated woodcreeper (Xiphorhynchus guttatus) is a species of bird in the subfamily Dendrocolaptinae of the ovenbird family Furnariidae.

It is found in Bolivia, Brazil, Colombia, Ecuador, French Guiana, Guyana, Peru, Suriname, and Venezuela.

Biogeography and molecular data suggest that the relationships among all eight subspecies and the taxa now included in X. susurrans deserve further study.

[4][7][8][9] Depending on the outcome of these studies, the name buff-throated woodcreeper could be restricted to X. g. guttatus alone, which is endangered by habitat fragmentation, making a change in conservation status necessary.

[7][8] The most likely evolutionary scenario is that from lower Amazonia, the ancestors of Lafresnaye's woodcreeper spread west- and southwestwards to the Andes, and those of the buff-throated and cocoa woodcreeper downriver and then along the coast of northern South America, where X. susurrans then branched off as the northern lineage.

Adults of the nominate subspecies X. g. guttatus have a dark brown face with narrow whitish buff streaks.

Their lower back and rump are cinnamon-rufous, their flight feathers darker rufous with dusky brownish tips on the primaries, and their tail rufous-chestnut.

Within the "buff-throated" group, the nominate X. g. guttatus is restricted to the humid tropical Atlantic forest.

The other two subspecies of the group inhabit semi-deciduous and gallery forest, palm swamps, treed areas of savanna, cerrado woodlands, and mangroves.

[10][11][12][13] All subspecies of the buff-throated woodcreeper are believed to be year-round residents of their respective ranges.

It regularly joins mixed-species feeding flocks, usually foraging from the forest's mid-level to the subcanopy but sometimes lower and higher.

[10][12] The buff-throated woodcreeper's breeding season varies widely across its large range.

All of the buff-throated woodcreeper subspecies are quite vocal; during their breeding seasons they sing for long periods at dawn and dusk and occasionally throughout the day.
