Nesting season is between February to June.  They usually nest in tree hollows on tall trees. The female stays inside the nest and nest entrance is sealed by the female using its excreta and mud-pellets supplied by the male. While inside the nest, the female moults her flight feathers and incubates the eggs.

Eggs 2 to 5, white in color. The regrowth of the female’s feathers coincides with the maturity of the chicks, at which point the nest is broken open. After the emergence of the female from the nest, she joins the male to feed the chicks in the nest.
