Behaviour
Breeding
They nest in tree cavities. Two eggs are laid. These birds are long-lived and form life-long partnerships. Females need to know that they can fully rely on their partner as during breeding the female is "bricked -up" into a tree-hole using dried mud/fruit puree/droppings. Here she lays and incubates whilst her partner brings her and her youngster all of their food. When the single youngster is large enough the female breaks out and both adults continue to feed the youngster.
Diet
The diet consists of a wide variety of fruit, particularly figs; they also take small animals and insects, including snails and millipedes.
