Primarily arthropods (insects, spiders, centipedes, larvae), foraging by probing bark crevices, gleaning from moss, and extracting prey from epiphytes.
A highly arboreal and diurnal species, the Olive-backed Woodcreeper spends its days meticulously exploring tree trunks and large branches. It employs a characteristic foraging strategy, climbing upwards in a spiral fashion, often bracing itself with its stiff tail feathers. Its specialized, decur...
The Olive-backed Woodcreeper is a resident species distributed across a wide, yet fragmented, range in the highlands of Central and South America.
