(Sagittarius serpentarius), a bird of prey of the family Sagittariidae. Up to 1 m tall, the secretary bird resembles a crane. The legs are long and powerful, and the talons are short. The plumage is gray and black. The feathers on the head are reminiscent of goose quills stuck behind the ear of a clerk—whence the bird’s name.
The secretary bird is found in steppe areas in sub-Saharan Africa. The nests are in trees or bushes at 2–6 m or higher; each clutch contains two or, less frequently, three eggs. The secretary bird feeds on locusts, termites, reptiles, birds, and rodents; it hunts on the ground. It kills its prey, for example, poisonous snakes, by striking it with its feet; it uses its wings to protect itself from bites. It is under legal protection everywhere. It sometimes attacks useful birds, such as partridges.
