The Diamantina sabrewing (Campylopterus diamantinensis) is a species of hummingbird in the family Trochilidae. It is found in southeastern Brazil where it is a resident of dry grasslands with thin soil and rocky outcrops.^[1]

Taxonomy and systematics[]

The Diamantina sabrewing was formerly considered to be a subspecies of the grey-breasted sabrewing (Campylopterus largipennis). It was accepted as a species by the South American Classification Committee of the American Ornithological Society in February 2020 and named in July 2020.^[2] The International Ornithological Congress followed suit in January 2021.^[3]

Description[]

The Diamantina sabrewing is a large hummingbird. Males weigh 8.4–10.2 g (0.30–0.36 oz) and females 7.0–8.6 g (0.25–0.30 oz). The upperparts are dark metallic green and the underparts dark gray. The proximal half of the four outermost retrices (tail feathers) are bluish black and the distal half white; the next two feathers are about 3/4 bluish black, and the two innermost feathers on each side are entirely bronzy green. The bill is slightly decurved, black above, and pinkish below.^[1][4]

Distribution and habitat[]

The Diamantina sabrewing is found only in the Espinhaço Range of Minas Gerais state of southeastern Brazil. It inhabits campos rupestre, a high elevation, dry, fire-prone biome between 1,100 m (3,600 ft) and 2,000 m (6,600 ft). The type locality is Córrego das Pedras in the municipality of Diamantina.^[1]

Status[]

The IUCN has not evaluated the Diamantina sabrewing. Lopes et al note that its habitat is "not subject to major direct human distubance" but that ongoing climate change will probably contract its elevational range. They therefore propose that the species be considered Endangered.^[1]
