Scissor-tailed kite

Scissor-tailed kite
The scissor-tailed kite (Chelictinia riocourii), also known as African swallow-tailed kite or fork-tailed kite, is a bird of prey in the monotypic genus Chelictinia in the family Accipitridae. It is widespread in the northern tropics of Africa.
Taxonomy and systematics
The species was illustrated in 1821 for a work by Coenraad Temminck, and described in 1822 by Louis Vieillot. It had been grouped with the Elanus kites or with the larger American swallow-tailed kite; in 1843 René Lesson assigned it to a separate genus, Chelictinia.
The genus name Chelictinia is possibly derived from Greek χελιδών or χελιδονι (chelidon), the swallow, with ικτινοσ (iktinos), the kite.
The specific epithet riocourii honours the Count Rioucour, Antoine François du Bois "first president in the Royal Court of Nancy, and possessor of a beautiful collection of birds". However, some sources refer to his son, Antoine Nicolas François, who was a contemporary of Vieillot.,
Description
The scissor-tailed kite is a small, slim grey and white kite with a relatively weak bill, a broad head, long pointed wings and a deeply forked tail. The adults are generally pale grey above and white below, with a white forehead and a black patch around the eyes. In flight the dark greyish flight feathers contrast with the inner underwing edges, there is also an obvious black bar across the carpal. Juveniles are darker on the back with rufous edges to the feathers and creamier below. It has a distinctive almost tern like flight and frequently hovers into the wind like a kestrel. The red eyes of the adult are also a distinctive feature.
Distribution and habitat
The species inhabits the arid savannah of the Sahel region of Africa, occurring mainly in a band between 8° and 15° N that stretches from Senegal on the west coast to Sudan in the east. There are also populations breeding in Ethiopia and Kenya."
It is found in many countries, including: Benin, Burkina Faso, Cameroon, Central African Republic, Chad, Ivory Coast, Djibouti, Eritrea, Ethiopia, Gambia, Ghana, Kenya, Liberia, Mali, Mauritania, Niger, Nigeria, Senegal, Somalia, Sudan, Togo, Uganda, and is also found in Yemen.
Behaviour and ecology
When breeding the scissor-tailed kite feeds mainly on skinks and other lizards, as well as small snakes, rodents and arthropods. Usually hunts on the wing, occasionally pursuing insects flushed by grass fires. When termites emerge or locusts swarm, there may be gatherings of scissor-tailed kites. Loose flocks have been known to associate with cattle, flying immediately overhead and hawking any insects that they flush.
They breed in loose colonies of up to 20 pairs, although will do so as single pairs, mainly on May to August but breeds in December to February in the west and March- June or August in Kenya. A small stick nest is built an acacia or thorny bush at 2-8m from the ground. The nest is often sited close to the nest of a large raptor such as a secretary bird or a brown snake eagle, occasionally close to buildings.
Status
The species is vulnerable to degradation of the habitat and pesticides. However, populations seem to be locally common in spite of decline in some parts of the range.
