A brown, tree-climbing bird with a strongly curved bill. Appears small-headed; plumage is mostly rufous-brown with buffy streaking on head and neck. Found in tall rainforest, where it is uncommon and locally distributed; often occurs in areas with extensive bamboo thickets. Generally shy and rather difficult to observe. Forages at middle and upper levels, using extraordinary bill to probe into deep bark crevices, bromeliads, and broken bamboo stems. Regularly follows mixed-species flocks. Song is variable, usually an accelerating series of strident whistles. Curved bill should immediately distinguish this species from most other woodcreepers in range. In western and central Amazonia, may overlap with Red-billed Scythebill, from which it may not be safely separable unless singing.
