The Black-winged Kite (Elanus caeruleus) is a small diurnal bird of prey in the family Accipitridae best known for its habit of hovering over open grasslands in the manner of the much smaller kestrels.
This kite is distinctive, with long-wings, white, grey and black plumage and owl like forward-facing eyes with red irises. Although mainly seen on the plains, they are sometimes seen on grassy slopes of hills in the higher elevation regions of Asia. They are not migratory, but make short-distance movements in response to weather.
This long-winged raptor is predominantly grey or white with black shoulder patches, wing tips and eye stripe. The long falcon-like wings extend beyond the tail when the bird is perched. In flight, the short and square tail is visible and it is not forked as in the typical kites of the genus Milvus. When perched, often on roadside wires, it often adjusts its wings and jerks its tail up and down as if to balance itself. The sexes are alike in plumage.
The prey include grasshoppers, crickets and other large insects, lizards and rodents. Injured birds, small snakes and frogs have also been recorded. The slow hunting flight is like a harrier, but it will hover like a Kestrel. It has on rare occasions been known to hunt prey in flight. Favourite perches are used for hunting and for feeding but large prey may sometimes be handled on the ground. In southern Africa, they appear to favour roadside verges for foraging and are sometimes killed by collisions with vehicles.
These birds roost communally with groups of 15 to 35 (larger numbers in Europe) converging at a large leafy tree. They are extremely silent and the calls recorded include a high-pitched squeal or a soft whistle. They call a lot mainly during the breeding season.
