Little Hermit occurs in northeastern South America, from northeastern Venezuela and Trinidad to French Guiana, and in adjacent far northern Brazil. As the name suggests, Little Hermit is one of the smaller species of hermit. These hummingbirds have olive green upperparts, an orange ochraceous belly, and white undertail coverts. Males have an intensely dark brown throat, while females have broader buff margins on the retrices than males. These hummingbirds inhabit the understory of open forest types from swamp and mangrove forest to dense second growth and forest edge. The Little Hermit feeds primarily on nectar and small arthropods. These birds are common or locally common throughout their range.
