Dry-forest Sabrewing

The outcrop sabrewing is very similar to its "parents", the grey-breasted and especially the Diamantina sabrewings. Males weigh about 7.0 g (0.25 oz) and females 5.9 g (0.21 oz). The sexes have almost identical plumage. Their bill is long and slightly decurved. Their upperparts are bright bronze green with coppery reflections on the darker crown. They have a white spot behind the eye. Their underparts are pale gray that lightens to whitish on the abdomen and light gray on the undertail coverts. Their central pair of tail feathers is bright bronze green, the next pair bright bronze green with a dark olive gray spot at the end, and the rest have bright bronze green bases, narrow dark olive gray bands near the tip, and white tips.

The outcrop sabrewing is found only in a small part of eastern Brazil. It is known from northeastern Goiás, southwestern Bahia, and northern Minas Gerais, and suspected to also be found in southeastern Tocantins and southern Piauí. Though exact details of its habitat requirements have not been determined, it is known mostly from dry forests on limestone outcrops and calcareous soils derived from them. It is known only in a very limited elevational range between 460 and 880 m (1,500 and 2,900 ft).

The outcrop sabrewing's foraging strategy and diet are poorly known, but it does take nectar from a variety of native and introduced plant species.
