Breeding

The nest is a large tree hole which is sealed with the female inside, incubating the eggs. There is a small hole to allow the male to pass food through to her. After hatching the female leaves the nest and re-seals the hole until the young are ready to fledge.

Diet

Feeds mainly on fruit but takes also some small animals.
