- Milvus migrans
Identification
Black Kite (Fork-tailed Kite-Australia) Milvus migrans RANGE Eurasia, Africa and Australia. Breeds across mainland Europe from Iberia east to the Urals. Common and widespread in Spain but patchy in France and central Europe, Italy and Greece. Absent from the British Isles and most of Scandinavia but a small number breed in southern coastal Finland and a rare breeder in Sweden. Has bred regularly in Belgium since the 1970s and first breeding for the Netherlands took place in 1996. Breeding in Finland in 2002 was the first for decades.
In Asia breeds across most of Turkey, the Middle East and the Arabian Peninsula and east across temperate and tropical Asia to the Pacific coast of Russia, Japan and China. To the south breeds throughout India and Sri Lanka and South-East Asia to southern Thailand. Also breeds in Sulawesi, eastern New Guinea and the Bismarck Archipelago. Widespread in much of Australia, particularly the north and centre and absent only from the southern coastal regions.
In Africa breeds across the North-West, in Egypt and throughout sub-Saharan Africa from Senegal to Somalia and south to the Cape. Also breeds in the Cape Verde Islands.
Northern populations are migratory and winter to the south. Most European birds winter in sub-Saharan Africa although a few may remain in southern Europe in winter and occasionally wintering birds occur north to southern Scandinavia. Dispersal of young birds can start in late June but migration begins in late July-August, and most have left breeding areas by September. Migrants concentrate at narrow sea-crossings during August-October, the peak period being mid-August to mid-September. Numbers are highest at Gibraltar, but also occurs in thousands at the Bosphorus and at Bor�ka in Turkey. Smaller numbers occur as migrants through Italy. The return movement in spring occurs February-May with a peak in March-April and the same routes are used. Regularly seen north of main breeding range and there has been some expansion of range in Europe in recent decades. Now annual in Britain ( c. 313 records), mostly in east and south-east England in the period mid April-early June with occasional autumn records. Breeding attempts may occur in Britain in the future.
Vagrants also recorded in the Channel Islands and Iceland. In Australia vagrants recorded on the south coast and Tasmania.
Habitat
Usually close to water, near rivers, lakes and seacoasts and in the south of range closely associated with man seen around towns and villages, refuse-tips and slaughterhouses. Breeds in tall trees in open or sparsely wooded country, usually gregarious, especially on migration.
Subspecies
About eight races are recognised. Nominate race occurs over most of the Western Palearctic with aegyptius in Egypt and Sinai, Somalia and Arabia, parasitus occurs in sub-Saharan Africa and tenebrosus on the Cape Verde Islands. M. m. lineatus is found in Central and eastern Asia, formosanus in Taiwan and Hainan, govinda from in India to South-East Asia and affinis from Indonesia to Australia.
