The secretarybird or secretary bird (Sagittarius serpentarius) is an African, primarily terrestrial, bird of prey. It is related to birds like vultures, hawks, and harriers. It has a distinctive appearance, as it has the body of an eagle, but the legs of a crane. These long legs make it tall, sometimes up to 1.3m.Its preferred habitat is open savannas or grasslands in sub-Saharan areas. It hunts in these open areas, using its long legs to strike prey and stomp them to death. It is famous for eating snakes, but it also hunts insects and small mammals. They mate for life and one pair inhabits and defends a territory of up to 50km. Pairs lay eggs in a nest of their own making at the top of Acacia trees. They live 10-15 years in the wild and up to 19 in captivity. They are classed as endangered, with their numbers rapidly decreasing due to habitat loss.
