11-11-2016 IRRAWADDY RIVER, MANDALAY - BLACK KITE (Milvus migrans)

The Black kite (Milvus migrans) is a medium-sized bird of prey in the family Accipitridae, which also includes many other diurnal raptors. It is thought to be the world's most abundant species of Accipitridae. Unlike others in the group, Black kites are opportunistic hunters and spend much time soaring and gliding in thermals in search of food. Their angled wing and distinctive forked tail make them easy to identify. They are also vociferous with a shrill whinnying call.

Black kites are generally dark in color. The upper plumage is brown but the head and neck tend to be paler. The patch behind the eye appears darker. The outer flight feathers are black and the feathers have dark cross bars and are mottled at the base. The lower parts of the body are pale brown, becoming lighter towards the chin. The body feathers have dark shafts giving it a streaked appearance. The cere and gape are yellow, but the bill is black. The legs are yellow and the claws are black. Males and females have the same plumage but females are longer than males.

Black kites are found in Europe, Asia, Africa, and Australia. European and central Asian birds are migratory, moving to the tropics in winter, but populations in warmer regions are residents. Black kites live in a wide variety of habitats from wetlands, river edges, coasts, grassland, open savannas, shrubland, and woodlands, to large cities. However, these birds try to avoid dense forests and high mountains.

Black kites are social raptors and in winter, they form large communal roosts. These birds hunt by day and are most often seen gliding and soaring on thermals as they search for food. They will swoop down with their legs lowered to snatch small live prey or carrion, for which behavior they are known in British military slang as the shite-hawk. The Indian populations are well adapted to living in cities and are found in densely populated areas. Large numbers may be seen soaring in thermals over cities. In some places, they will readily swoop and snatch food held by humans. Black kites are very vocal birds; they communicate with a distinctive shrill whistle followed by a rapid whinnying call.
