Breeding

Secretarybirds are monogamous(mate for life); They can breed at any time of the year, but more frequently in the late dry season. The Secretarybird’s nest is a large platform that is made of sticks, and placed on the top of a tree. The nest is lined with grass, wool, and mammal dung. The female lays a clutch of 1 to 3 eggs. The eggs are white with very sparse dark markings. Both the male and female incubate the eggs for 42 to 46 days. When the chicks need nourishment the parents will regurgitate food; the parents regurgitate water for their chicks as well. The offspring remain dependent on their parents from 2 to 3.5 months. 

Diet

The Secretarybird eats insects, frogs, lizards, small tortoises, snakes  (including venomous species), birds, small rodents, hedgehogs, mongooses, squirrels, hares, crabs, and eggs.

Conservation Status
