[edit] Distribution

From South Sudan to northeast Uganda and in northwest Kenya.
Widespread and locally common.

[edit] Taxonomy

This is a monotypic species.
Formerly considered a subspecis of Von der Decken's Hornbill.

[edit] Habitat

Thorn scrub and similar arid habitats.

[edit] Behaviour

The diet includes insects, fruit and seeds.
Forages mainly on ground but also high up in fruiting trees.
Breeding season February to July. 2-4 white eggs are laid in a tree hole, which is blocked off with a cement made of mud, droppings and fruit pulp. There is only one narrow opening, just big enough for the male to transfer food to the mother and the chicks. Once the chicks and the female are too big to fit in the nest, the mother breaks out and rebuilds the wall, then both parents feed the chicks.
