According to checklist of Birds of the World, Accidental birds are not endemic to Nigeria they just happen to be found here! And amazingly way more than the endemic ones!
Endemic birds are therefore, birds specifically found in Nigeria, and they are grouped into FOUR namely:
THE IBADAN MALIMBE
The Ibadan malimbe (Malimbus ibadanensis) is a rare species of Bird.
It is endemic to Nigeria, where it is known only from the southwestern part of the country. It was first discovered in 1951 and was common at one point, but forest clearing made it rare.
Identification
The bird is about 20 centimeters long. The male is black with a red head and breast. The female has smaller red areas.
The bird forages in pairs or small groups, sometimes alongside the red-headed malimbe (Malimbus rubricollis).
Habitat
It lives in forest and woodland habitat, including degraded areas.
THE ANAMBRA WAXBILL
The Anambra waxbill (Estrilda poliopareia) is another specie of bird found in wetter land of southern Nigeria.
Identification
The anambra waxbill is approximately 12cm long. This species of a dun-coloured finch with reddish brown bill and rump. If looked at closely, it has very fine barring on it upper parts, sides of breast and flanks, with unusual pal eyes. It has a typical waxbill-like tzzt... call.
Habitat
The Anambra waxbill lives in small flocks of up to 20 birds or more. It appears to be found at southern Nigeria, and is known with certainty from only five reported sightings. It is usually found in long grass along rivers, lagoon sandbanks, marshes, swamps and forest. It feeds principally on grass seeds taken from seedheads.
ROCK FIREFINCH
The Rock firefinch (Lagonosticta sanguinodorsalis) is another specie found in northern Nigeria. It has an estimated global extent of occurrence of 29,000 km². The status of the species is evaluated as Least Concern.
Identification
The Rock firefinch has a blue-grey bill, red back in the male and reddish brown back in the female and juvenile and broad primaries in both the adult and juvenile.
Location
It is commonly found in bushy and rocky outcrops on the Jos Plateau. It probably feeds on grass seeds. Yea, think i remember this particular bird while in Jos!!!!
JOS PLATEAU INDIGOBIRD
The Jos Plateau indigobird (Vidua maryae) is a species of bird in the Viduidae family. Also endemic to Nigeria.
It lays its eggs in the nest of the rock firefinch which is also restricted to Nigeria. Because of their inability to incubate their eggs, they lay their eggs in the nest of the rock firefinch and then take away the exact number of laid eggs from the host bird in order to avoid suspicion from the host bird . After hatching they exhibit dominance against the hatchlings of the rock firefinchers.
Their breeding seasons are all round the year but more pronounced during the cold Harmattan period between July and December.
Habitat
Its natural habitats are dry woodland and shrubland in rocky areas. It is threatened by habitat loss.
