The Bateleur (Terathopius Ecaudatus) is a medium-sized eagle in the bird family Accipitridae which also includes many other diurnal raptors such as buzzards, kites and harriers. It is the only member of the genus Terathopius and probably the origin of the "Zimbabwe bird", national emblem of Zimbabwe.
The Bateleur eagle is a common resident species of the open savanna country in Sub-Saharan Africa, though it also occurs in south-west Arabia. It nests in trees, laying a single egg which is incubated by the female for 42 to 43 days, with a further 90 to 125 days until fledging. Bateleurs pair for life, and will use the same nest for a number of years. Unpaired birds, presumably from a previous clutch, will sometimes help at the nest.
The wind blows from the back side, that's why the feathers stands wide out.
