23-12-2022 BRUFUT FOREST, GAMBIA - AFRICAN BLACK WINGED KITE (Elanus caeruleus ssp. caeruleus)

The black-winged kite (Elanus caeruleus), also known as the black-shouldered kite (not to be confused with the closely-related Australian species of the same name), 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 Palearctic and Afrotropical species was sometimes combined with the Australian black-shouldered kite (Elanus axillaris) and the white-tailed kite (Elanus leucurus) of North and South America which together form a superspecies. This kite is distinctive, with long wings; white, grey and black plumage; and owl-like forward-facing eyes with red irises. The owl-like behaviour is even more pronounced in the letter-winged kite (Elanus scriptus), a nocturnal relative in Australia. Although mainly seen on plains, they are sometimes seen on grassy slopes of hills in the higher elevation regions of Asia. They are not migratory, but show nomadism in response to weather and food availability. They are well adapted to utilize periodic upsurges in rodent populations and can raise multiple broods in a single year unlike most birds of prey. Populations in southern Europe have grown in response to human activities, particularly agriculture and livestock rearing.

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 possibly in West Asia. The first records of breeding in Europe were in the 1860s and since then they have become more widespread and populations are on the rise. It is thought that land-use changes, particularly agriculture and pastureland have helped the species.The species has expanded its range in southern Europe.

Several geographic populations have been named as subspecies and these include the nominate subspecies which occurs in Spain, Africa and Arabia. The subspecies vociferus is found east of this range across South Asia and into Southeast Asia. Along Sumatra, Java, Borneo and the Philippines subspecies hypoleucus (sometimes considered a full species) includes the population wahgiensis described from New Guinea. Subspecies sumatranus is not always recognized. The white-tailed kite and the black-shouldered kite were formerly included with this species but have since been treated as separate species.

Although found mainly on the plains they have been seen at higher altitudes in Sikkim (3,650 m (11,980 ft)), the Nilgiris (Doddabetta, 2,670 m (8,760 ft))[23] and Nagaland (2,020 m (6,630 ft)).

They are said to be winter visitors in some parts of their range such as the Western Ghats.

5-6-2019 LINYANTI CAMP, BOTSWANA - AFRICAN BLACK WINGED KITE (Elanus caeruleus ssp. caeruleus)

The Black-winged Kite, Elanus caeruleus, is a small diurnal raptor with a striking appearance. It is characterized by its long wings and a contrasting pattern of white, grey, and black plumage. The bird's forward-facing eyes with red irises are reminiscent of an owl's gaze, lending it a distinctive look among birds of prey.

Adults of this species can be identified by their black shoulder patches, wingtips, and the distinctive eye stripe. In flight, the long wings extend beyond the tail, which is short and square, lacking the fork seen in typical kites like those in the genus Milvus. When perched, the bird may adjust its wings and jerk its tail, as if maintaining balance. Both sexes have similar plumage.

The Black-winged Kite is typically found in open land and semi-deserts, favoring open grasslands where it can easily spot prey. It is also seen on grassy slopes at higher elevations in parts of Asia.

This species has a wide range that includes sub-Saharan Africa, tropical Asia, and parts of Europe. It has been observed at altitudes as high as 3,650 meters in Sikkim and is known to be a winter visitor in some regions, such as the Western Ghats.

The Black-winged Kite is known for its habit of hovering over grasslands, much like kestrels. It is not migratory but displays nomadic behavior in response to weather and food availability. It is capable of raising multiple broods in a year, taking advantage of surges in rodent populations.

The calls of the Black-winged Kite are high-pitched squeals or soft whistles, mainly heard during the breeding season and at communal roost sites.

Breeding occurs at various times across its range, with nests being a loose platform of twigs. The species lays 3 to 4 pale creamy eggs with deep red spots. Both parents incubate, but the male takes on a more significant role in foraging as the chicks grow.

The Black-winged Kite can be confused with the closely-related Australian Black-shouldered Kite (Elanus axillaris) and the White-tailed Kite (Elanus leucurus) of North and South America, which together form a superspecies.

Its diet consists of large insects, lizards, and rodents, with occasional small snakes and frogs. The kite hunts by flying slowly or hovering like a harrier and sometimes hunts prey in flight.

The IUCN Red List classifies the Black-winged Kite as Least Concern, indicating a stable population trend. However, it benefits from human activities such as agriculture and livestock rearing, which have contributed to its range expansion in southern Europe.
