Compared to most congenerics, Golden-winged Tody-Flycatcher inhabits a comparatively small range, being confined to southeastern Colombia, eastern Ecuador, and extreme northeastern Peru, entirely north of the Amazon. It is not rare, but, like other species of Poecilotriccus, easily is overlooked without appropriate knowledge of its vocalizations. In plumage, its black head, broad white throat, large yellow wingbar, chestnut shoulder patch, and bright yellow underparts make this an easily identified, and beautiful, bird. Golden-winged Tody-Flycatcher has been recorded to 1450 m in the eastern foothills of the Andes, and it inhabits dense undergrowth in lowland forest and edges, sometimes even being found in overgrown pastures or large gardens. Virtually nothing is known concerning its ecology.
