Black-winged Kite

Appearance

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. Their large forward-facing eyes and velvety plumage are characters that are shared with owls and the genus itself has been considered as a basal group within the Accipitridae.

Distribution

The Black-winged Kite is a species primarily of open land and semi-deserts in sub-Saharan Africa and tropical Asia, but it has a foothold within Europe in Spain and Portugal. The species range appears to be expanding in southern Europe and possible in West Asia.

Behavior

The Black-winged Kite breeds at different times of the year across its range. Although nesting has been noted throughout the year in India, they appear not to breed in April and May. Courtship is noisy and involves chases and once the pair is formed they copulate frequently.

The nest is a loose platform of twigs in which 3 or 4 eggs are laid. The female spends more effort in the construction of the nest than the male. The eggs are pale creamy with spots of deep red. Both parents incubate but when the chicks hatch, the male spends more time on foraging for food. Females initially feed the young, sometimes hunting close to the nest but will also receive food from the male. After fledging the young birds continue to be dependent for food on the male parent for about 80 days, initially transferring food at perch and later in the air.

Food

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.
