[edit] Behaviour

[edit] Actions

It perches conspicuously while looking for insect prey, before dropping to the ground to catch it. Flight is low, slow and quiet. It also performs aerial sallies when hunting, and can hover for long periods almost motionless.

[edit] Breeding

Nests in cavities, a hole in tree or an abandoned nest of Rufous Hornero. Inside the cavity, the birds build a large open cup made with twigs and grass, and the interior is lined with finer materials such as feathers or hair. The female lays 3-4 white eggs with fine reddish and grey markings. The incubation lasts 12-14 days. The chicks are fed by both adults, and fledge about 17 days after hatching.

[edit] Diet

Feeds exclusively on insects caught by aerial sallies from exposed perches.

[edit] Vocalisations

Male's dawn song is a soft, repeated preeeyp tooit preeeyp tooit given during breeding season. Otherwise usually silent except for an occasional weak ghik and a plaintive piew.
