The planalto woodcreeper (Dendrocolaptes platyrostris) is a sub-oscine passerine bird in subfamily Dendrocolaptinae of the ovenbird family Furnariidae.

Adults of the nominate subspecies have a dusky face with bold buffy streaks and a faint supercilium.

Their belly, flanks, and undertail coverts are buffy brown with thin blackish bars.

Subspecies D. p. intermedius is paler than the nominate with a more cinnamon color overall, a dusky brown or olive crown, few or no streaks on the back, and more rufous wings, rump, and tail.

D. p. intermedius occurs in dryer habitats such as deciduous woodland, palm swamps, and gallery forest in relatively open caatinga and cerrado.

When attending ant swarms it perches low to the ground and sallies to capture prey.

Away from ants it forages at all levels of the forest both by sallies from a perch and by gleaning from foliage and bark.

[5] The planalto woodcreeper's breeding season appears to vary somewhat geographically but generally is within October to January.

It is thought "only moderately sensitive to human disturbance, which may explain continued presence at many somewhat degraded sites.
