Red-necked falcon

Appearance

The red-necked falcon is a medium-sized, long-winged species with a bright rufous crown and nape. It is on average 30–36 cm in length with a wingspan of 85 cm. The wings and upper parts are bluish grey and the tail has narrow bars, a broad subterminal black band tipped with white. The wingtip does not reach the tip of the tail at rest. The second and third primaries are the longest and almost equal in length while the first is a fourth the length. The first two primaries are notched. The legs, ceres and eyering are yellow. The tip of the bill is black while the basal portion is greenish yellow. The voice of this species is a shrill ''ki-ki-ki-ki''. The sexes are similar except in size, males are smaller than females as is usual in falcons. Young birds are buff below with less extensive barring and duller upper plumage.

Distribution

In Africa, the red-necked falcon is found in semi-desert, savannah and other dry open country with some trees, but also riverine forest. It often perches and makes use of the crowns of Borassus palms for breeding. They are mostly resident but may make nomadic movements in response to weather. In India, they are found in open habitats and is not found in dense forests or high hills. The nominate subspecies is believed to have occurred west until Iran although no records exist from there since 1970. They were recorded breeding in 1911 by Nikolai Zarudny. It is a winter vagrant in northern Sri Lanka where it was first recorded by E.L. Layard.

Behavior

The red-necked falcon usually hunts in pairs, often at dawn and dusk, sometimes utilizing a technique in which one of the pair flies low and flushes up small birds while the other follows higher up and seizes the prey as it flushes from cover. They fly with a fast and dashing flight.

The red-necked falcon drinks water where available during the afternoons. This has been observed both in India and in Africa, where it sometimes visits waterholes.

Reproduction

The breeding season in India is January to March. In Zambia, the breeding season begins in August. Pairs may indulge in courtship feeding in which the female feeds the male, an unusual behaviour that has also been noted in captivity. This falcon often reuses the old tree nests of corvids, or lays its 3-5 eggs in a nest that it builds on the fork of a tall tree or in the crown of a palm tree. In Africa, they have been known to reuse the nests of pied crows , African fish eagles on ''Acacia'' apart from building their own nest in ''Borassus'' palms. In India, the nest is often placed in a large mango tree and concealed inside foliage. The nest territory is well-guarded and crows and kites driven away. This falcon has been documented to nests in trees amidst dense human population. The clutch consists of two to four eggs which are incubated only by the female which begins after the last egg of the clutch is laid. The eggs hatch after about 32 to 34 days and the newly hatched young are covered in white down and are brooded by the female for a week. The male brings food which is torn by the female and fed to the chicks. The young fledge in about 35 to 37 days in Africa and up to 48 days in India.
