About Eupetomena cirrochloris (Vieillot, 1818)
The sombre hummingbird, scientifically named Eupetomena cirrochloris (Vieillot, 1818), measures approximately 12 cm (4.7 in) in length and weighs between 7.1 and 9 g (0.25 to 0.32 oz). The two sexes have essentially identical appearance, though females are slightly smaller than males. This species has a slightly decurved black bill. Its upperparts range from bronzy green to blackish bronzy green, with a coppery sheen on the uppertail coverts. Its underparts are dull gray, with a small number of dull green spots on the throat. It has a square-tipped tail: the central tail feathers are shiny green, while the remaining tail feathers are black with a bronzy gloss. The sombre hummingbird is distributed across eastern Brazil, ranging from Pernambuco south into Rio Grande do Sul and extending west as far as Mato Grosso. It inhabits the edges and understory of humid primary and secondary forest, as well as plantations and gardens. The core of its range is within the Atlantic Forest, but it also occurs in the transition zone between the cerrado and caatinga biomes.
