Behaviour

Diet

Their diet consists almost entirely of insects such as weevils and grasshoppers.

Breeding

They construct huge nests made from thorny sticks in baobabs and other large trees, as well as on power pylons; these are used as communal roosts. They may have a second brood each year.

Other species, such as Verreaux's Eagle-Owl, also utilise them for overnight roosting.
