This diminutive aerial insectivore measures a mere 14-19 cm (5.5-7.5 in) in length with a wingspan of 30-40 cm (12-16 in) and weighs between 20-30 g (0.7-1.1 oz).

Found primarily in open, dry habitats such as savannas, grasslands, cerrados, and clearings, often with scattered trees or shrubs, from lowlands up to approximately 1,500 meters (4,900 feet) in elevation.
