[edit] Behaviour

The diet includes mainly fruit, but some insects, lizards, and bird eggs are also taken. Forages usually singly, sometimes in groups.
Breeding generally from March to July, locally starting in February and lasting to November. They nest in an unlined cavity in a tree; 3-4 white eggs are laid and incubated by both sexes for 14–15 days. Both parents care for the young which fledge after about 6 weeks.
