Taxonomy

Diet

Their diet consists mainly of lizards, snakes and small birds; small mammals and insects are also eaten.

Breeding

They build a large stick nest on a cliff or sometimes a tall tree. Two eggs are incubated mostly by the female for 39-45 days; the second egg hatches about a day after the first. The younger chick is usually killed by its sibling within a few days. The surviving chick fledges after about 30 days and the nestling period is about 50 days.
