This small nighthawk flies by night over open grassland and catches airborne invertebrates. A breeding record in Misiones, Argentina, also describes one female and a nest on the ground.
One adult female captured at a nest in Misiones in 1995 had a pale rufous-brown head and breast, a white inverted-V throat mark, and black bars on an ashy belly.
It is nocturnal and catches airborne invertebrates over open habitats such as savanna and forest edge. A Misiones report recorded one egg in a nest site on the ground.
At the Misiones nest in 1995, the cream egg had brown spots of different sizes and a few grey-olive marks. It lay on a roughly 5 cm patch of disturbed soil, bordered on one side by small stones.
The female caught at a Misiones nest in 1995 had a white band across the three outer primaries, white secondary tips forming a clear wing edge in flight, and white tips to the outer tail feathers.
