The scissor-tailed kite, also known as African swallow-tailed kite or fork-tailed kite, is a bird of prey in the monotypic genusChelictinia 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 nameChelictinia is possibly derived from Greek χελιδών or χελιδονι, the swallow, with ικτινοσ, the kite. The specific epithetriocourii 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.
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, dropping onto prey but does catch prey in flight, especially insects flushed by grass fires. When termites emerge or locust swarms there may be gatherings of scissor-tailed kites. Loose flocks have been known to associate with cattle, flying over the beasts and hawking any insects 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.
