Justification
This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend appears to be stable, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size may be moderately small to large, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.

Red-necked Falcon

The Red-necked Falcon or Red-headed Merlin (Falco chicquera) is a bird of prey in the falcon family. This bird is a widespread resident in India and adjacent regions as well as sub-Saharan Africa. It is sometimes called Turumti locally.

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 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.

The adult of the African subspecies Falco chicquera ruficollis has a white face apart from black moustachial stripes. The upperparts are pale grey, with black primary wing feathers and tail tip. The underparts are white with dark barring on the underwings, lower breast, belly and undertail. There is a buff foreneck band. The legs and eyering are yellow. The voice of this species is a shrill kek-kek-kek.

West African males are known to weigh between 139 and 178 grams, while females are found between 190 and 305 grams. The particularly large African birds from south of the Zambezi River are often separated as subspecies Falco chicquera horsbrughi, but the size variation may be clinal and the latter subspecies not valid.

The Asian nominate subspecies Falco chicquera chicquera has rufous moustachial stripes, lacks the buff breast band, and is less extensively barred than the African subspecies.

The Red-necked Falcon is of unclear relationships. While it is sometimes allied with the Merlin or the African Hobby, this is most probably not correct. It might actually be distantly related to the Peregrine Falcon but much more study is needed to resolve this problem. In any case, the African and Indian forms are very distinct and have probably been separated for a long time; they might be considered distinct species.[2]

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 hidden in the crown of a Borassus palm (Borassus aethiopium), and chases birds, bats and large insects with a fast dashing flight. It is most active at dawn and dusk, hunting below the tree canopy. It often hunts in pairs, 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 rises from cover.

This falcon reuses the old tree nests of corvids, or lays its 3-5 eggs in the debris in the crown of a palm tree.
