Brazilian name: Arapaçu-liso

The Plain-winged Woodcreeper is found in south-east Brazil from southern Bahia and into Misiones, Argentina.

It inhabits forest and secondary woodland where it is usually seen in lower and middle levels. It often follows army ant swarms.

Distinguishing features are its lack of any. It is plain brown all over including on the wings. It has faint buff streaking on the crown feathers which you can see in most of these photos. The throat is a plain buff colour and the bill is short and straight.

The genus Dendrocincla is considered to be the most primitive of the woodcreepers. The tail feathers have a less rigid shaft and smaller spiny tips than others. This is possibly related to the fact that they catch much of their prey by sallying rather than foraging on tree trunks.

There are recordings of its rather monotonous song on xeno-canto, a distribution map from NatureServe and additional information available via Avibase. There is also a page on Wikiaves.
