Breeding:
These birds can breed all year round, nesting in colonies in the jungle, between palms and mangroves or in cavities of old buildings. The nest is a platform made of sticks, twigs and leaves and lined with seaweed. There the female lays 2-4 green-blue eggs which are incubated by both parents for 25-28 days. The chicks are fed by both parents and fledge 5-6 weeks after hatching.

This species has a very large breeding range and a global population of 100.000-1.000.000 individuals. The population is suspected to be stable in the absence of evidence for any declines or substantial threats.
