Small hummingbird with a long white-tipped tail. Its rufous underparts, green back, and striped face are features typical of many hermits, but the dark throat and white vent help separate it from other similar species. Inhabits rainforest understory in lowlands east of the Andes and in adjacent foothills. It is difficult to see well as it zips between flowers in the gloom. Sometimes gives a high-pitched, squeaky song from a low perch.
