Secretary Bird

The Secretary bird, belonging to genus Sagittarius, is a large bird of prey. This species is mostly terrestrial. They are endemic to Africa, found primarily in savannahs and grasslands. Even though it is a member of order Accipitriformes (like a lot of diurnal raptors, such as harriers, vultures, hawks and kites), yet they belong to a new family Sagittariidae. Its common name is believed to have come from the crest of quill-like feathers, offering an appearance of a secretary with quill pens places in their ear. However, a recent conjecture suggests that the term ‘secretary’ comes from a French misrepresentation of Arabic “saqr-et-tair” that means “hunter-bird”.

The habitat

The geographical range of Secretary Bird

They are found almost all across Africa (including south of Sahara) apart from the desert along the Namib coast, the wooded region around the equator in West Africa. They are not found in Ghana, Nigeria, Cote d’Ivoire, southern regions of Guinea, and the sub-Saharan countries of Liberia and Sierra Leone.

Behaviour and Adaptation of Secretary Bird

Secretary birds are not social in general, but at times, they can be seen hunting in small groups. They keep in touch with each other by hooting. This species is territorial and one individual’s range can be up to 40 or 50 square kilometres. They can cover up to twenty miles in a single day just by walking. They are a quite skilled flier, but they spent most of their time on the ground. They take a long run before taking off to the air.

Reproduction of Secretary Bird

This species is monogamous. Courtship display includes guttural croaking and undulating flight patterns. At times, both male and female get involved in ground displays, such as chasing each other. Both male and female call on to the nest site at least six months before egg laying takes place. Nests are mostly made with sticks, and they can be placed at a height of around 20 feet. Most of the times, copulation takes place on the ground, but they can also mate in Acacia trees. Females lay 2 to 3 pale green, oval, rough textured eggs over a period of two or three days. Female incubates the eggs for 45 to 50 days. Juveniles are covered with downy plumage. Parents feed them with regorge food. The young ones become capable of flapping wings in 60 days time and they can fledge when they are about 80 days old. The young birds stay around the breeding nest for another 80 to 105 days. During this time, they go to hunting expeditions with their parents.
