Hummingbird endemic to Brazil. Occurs in central-eastern Brazil, from Pernambuco to Rio Grande do Sul, Goiás and Mato Grosso. The core of its habitat is the Atlantic Forest but it also occurs in the transition zone between cerrado and caatinga biome. The Sombre Hummingbird is a large, dull hummingbird having a rather heavy, slightly decurved black bill, rather broad wings, and a large tail. Their upperparts are bronzy green to blackish bronzy green with a coppery sheen to the uppertail coverts. Their underparts are dull gray with a few dull green spots on the throat. Their tail is square; its central feathers are shiny green and the rest black with a bronzy gloss. The Sombre hummingbird forages for nectar at a variety of flowering plants. In addition to nectar, it feeds on arthropods captured by hawking from a perch.
