Distribution

The Nacunda Nighthawk is found in South America east of the Andes in two groups: Colombia, Venezuela, the Guianas and extreme north of Brazil; and south of the Amazon to central Argentina.

Taxonomy

Two subspecies are recognized[1]:

  • C. n. minor
  • C. n. nacunda

This species was recently transferred from the genus Podager to Chordeiles. In consequence a new name is needed for one of the subspecies, P. n. minor would become Chordeiles nacunda coryi.

Habitat

Habitats include forest edges, river edges, savanna and marshes, often where these are surrounded by drier, open country.

Behaviour

Mainly nocturnal, sometimes crepuscular. In flight sometimes glides on wings raised in a dihedral, and often foraging in groups. Spends the day on the ground on for example sand banks, sometimes in quite large groups.
