Diet

It feeds mainly on lizards and snakes, but will also take insects (such as beetles and grasshoppers), small mammals (such as rabbits, squirrels and mice), birds (such as quails and nestling doves), frogs, toads, other amphibians and fish. [3] [4] [5] [6] It usually sits on an open high perch from which it swoops on its prey, but will also hunt from a low glide.

Breeding

The nest is of sticks and built high in a tree. The usual clutch is one to three, usually two white to pale blue eggs. [7] The young take about 6 weeks to fledging.
