Description

The Diamantina sabrewing is a large hummingbird, about long. Males weigh about and females . The sexes have almost identical plumage including a white spot behind the eye. Their bill is long and slightly decurved; the maxilla is black and the mandible whitish with a brownish tip. Male's upperparts are dark grass green with a darker crown and their underparts dark gray. Their tail's central two pairs of feathers are metallic bronze-green. The other three pairs have bright bronze-green bases that grades through dark olive gray to a wide white tip. The female differs only by being a slightly duller green.Greeney, H. F. (2021). Diamantina Sabrewing (''Campylopterus diamantinensis''), version 1.0. In Birds of the World (H. F. Greeney, Editor).

Behavior

Movement

The Diamantina sabrewing's movements, if any, have not been documented.

The Diamantina sabrewing's foraging strategy and diet are not known but are assumed to be similar to those of its former "parent" the grey-breasted sabrewing.

Breeding

Nothing is known about the Diamantina sabrewing's breeding

Vocalization

The Diamantina sabrewing's vocalizations are very poorly known. As of mid-2022 xeno-canto has no recordings and the Cornell Lab of Ornithology's Macaulay Library only two. The species' original description noted that its alarm call is "a strong, rapidly repeated single note: ''ché, ché, ché, ché, ché, ché''."Ruschi, A. (1963).

has assessed the Diamantina sabrewing as Near Threatened. It has a very small range and its population size is unknown and believed to be decreasing. Its already restricted habitat is projected to further decrease in area due to climate change. Its habitat "is not presently experiencing major direct human disturbance" and part of it is protected in two national parks.
