Predators and parasites
Movements and migrations
Little known, but probably resident and
Mainly eats flying insects, foraging both close to the
ground and at higher altitudes. The following food items have been recorded
in its diet:
- 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.
