Predators and parasites

Movements and migrations

Little known, but probably resident and sedentary.

Food 

Mainly eats flying insects, foraging both close to the ground and at higher altitudes. The following food items have been recorded in its diet:

Breeding

  • Monogamous, usually nesting in colonies of approximately 25 nests, with each pair fighting vigorously for control of a nest site.
  • The nest is a strongly-built half cup with a rim of feathers, seeds and leaves, glued together with saliva and typically placed beneath an overhang or in the vertical crack of a cave.
  • Egg-laying season is from June-January, peaking from June-September.
  • It lays 1-3 eggs, which are incubated by both sexes.
  • Little is known about the chicks, besides that they probably learn to fly at about 28 days old.

Threats

Not threatened.
