Characterization: Small species measuring about 13cm in length. Very thin species with a long, deeply forked tail that is usually kept closed during flight, a dark upper body with feathers with creamy-colored edges, and a grayish white belly.

Distribution: The Guianas and Venezuela to Mato Grosso, Goiás, Minas Gerais, and Bahia.

Habitat: Palm trees with fan-shaped leaves, especially Moriche palm groves and "miriti." They are in all areas where these trees occur, also using carnauba and exotic palms that have the same type of palm.

Habits: Diurnal species, usually found in pairs or flocks, which install themselves in a single palm tree, spending the night and nesting on its edges.

Diet: Carnivorous, this bird feeds mostly on insects they catch in flight.

Breeding: They lay 2 eggs in a nest fixed laterally by saliva to the ribs of palm leaves which consists of a wad of soft and loose feathers, narrower at the top and wide and open at the bottom where access is located.

In the UFRA area: In the studies don at the São Francisco Sugarmill areas, this bird's distribution was limited to wetlands with herbaceous plants. As it was only seen twice, it is considered rare within these farms.
