Bananal Antbird

The Bananal antbird is 16 cm (6.3 in) long; one individual weighed 15 g (0.53 oz). Adult males are almost entirely black, with white edges on their outer scapulars, a white patch between them, and a hidden white patch under them. Their wing coverts and tail feathers have white tips and their flight feathers have white inner edges. Females are mostly gray, with white in the same places as the male and thin white streaks on their throat and breast.

The Bananal antbird is found along the Araguaia and Tocantins rivers and some of their tributaries in central Amazonian Brazil. Its range is centered on the large Ilha do Bananal in the Araguaia. Its range extends from northwestern Goiás and eastern Mato Grosso north through western Tocantins into southeastern Pará and western Maranhão. The species inhabits gallery forest and nearby mature secondary forest that is also near water such as oxbow lakes. It occurs almost entirely in vine tangles and other dense vegetation from the understorey to the mid-storey.

The Bananal antbird's diet has not been detailed but is known to be insects and probably includes spiders. Individuals, pairs, and family groups usually forage between about 3 and 15 m (10 and 50 ft) above the ground, but also regularly pursue prey to the ground. They seldom join mixed-species feeding flocks.
