1 / 2

Characterization: Species measuring about 19.5cm. It has black uniform with a silky shine. Females and immature tawny-headed swallows have a darkish-brown, striated and olive-colored upper side, wings with rufous edges, a dirty yellow, somewhat intermixed black bottom side. Sharply pointed beak.

Distribution: North of the Lower Amazon, Maranhão, Bahia, Minas Gerais, Rio de Janeiro, São Paulo, Goiás, Mato Grosso, Paraguay, Bolivia, and Argentina.

Habitat: Swamps.

Habits: When it frightens a rival it moves obliquely forward, in silence.

Diet: It searches for maggots and flies among plants or eats fruit.

Breeding: There are notable prenuptial ceremonies. They build a nest that is similar to a deep, well lined open basket, which is built on a fork of a tree close or a few meters above the ground. It has an average of two litters per season, with 3 eggs each.

In the UFRA area: This bird, which spotted in the São Francisco Sugarmill areas, is considered rare in the surveys because it was spotted only once. Its spatial distribution was limited to wetlands with herbaceous plants.
