Top 20 Most Common Bird in Sierra Leone

Black Kite is a bird of prey known for its aerial skills and hunting ability. Its striking appearance makes it a fascinating species to observe, and it can often be seen soaring through the skies. Black Kite is highly adaptable and can be found in a variety of habitats, making it a common sight in many areas.

The variable sunbird (or yellow-bellied sunbird), Cinnyris venustus (formerly Nectarinia venusta), is a sunbird. The sunbirds are a group of small Old World passerine birds which feed largely on nectar, although they will also take insects, especially when feeding young. Flight is fast and direct on their short wings. Most species can take nectar by hovering like a hummingbird, but usually perch to feed most of the time. The variable sunbird is a fairly common resident breeder in equatorial Africa. Two eggs are laid in a suspended nest in a tree. This species is found in open woodland and cultivation. Variable sunbirds are small, only 10 cm long. They have medium-length thin down-curved bills and brush-tipped tubular tongues, both adaptations to their nectar feeding. The adult male has a glossy green head, throat and nape, and a maroon breast band. In most subspecies, the belly of the male is yellow, but in a few it is orange or white. The female has grey-brown upperparts and yellowish underparts, and an obvious pale supercilium. The eclipse male is like the female, but shows some green, especially on the throat. The call is a clear tew-tew-tew-tew-tew .

It is approximately the size of the European carrion crow or a little larger (46–50 cm in length) but has a proportionately larger bill, slightly longer tail and wings, and longer legs. As its name suggests, its glossy black head and neck are interrupted by a large area of white feathering from the shoulders down to the lower breast. The tail, bill and wings are black too. The eyes are dark brown. The white plumage of immature birds is often mixed with black. It resembles the white-necked and thick-billed ravens but has a much smaller bill.

The bill is fairly short and thin, with a slightly downcurving upper mandible. The bill, legs, and feet are black and the eye is dark brown with a dark eye-ring, which is not readily visible. It is about 18 cm in length, with a long tail. It has a dark brown head and upperparts. Sexes are similar in plumage.

The laughing Dove is a small dove named after its distinctive laugh-like vocalization. This ground-feeding, non-migratory bird is a regular inhabitant of man-altered environments such as villages, gardens, and orchards. In cities, these doves tend to become quite confident. They pair for life and live in very small communities.

The northern grey-headed sparrow (Passer griseus), also known as the grey-headed sparrow, is a species of bird in the sparrow family Passeridae, which is resident in much of tropical Africa. It occurs in a wide range of open habitats, including open woodlands and human habitation, often occupying the same niche as the house sparrow does in Eurasia. The adult northern grey-headed sparrow has a pale grey head with a white moustache stripe, pale brown upperparts, whitish underparts and chestnut wings with a small white shoulder patch. The sexes are similar, but young birds are slightly duller and lack the white wing patch. There are three subspecies, differing in plumage tone, especially with regard to the darkness of the head. This sparrow is mainly resident in its range, but there is some seasonal movement, and flocks of up to 50 birds form outside the breeding season. It builds a cup nest in trees, thatch, or old nests of other birds; 2–4 eggs are laid. This species feeds principally on seeds and grain, like other sparrows, but will readily take insects including termites, especially when feeding young. The calls include cheeps and chirps, and the typical sparrow churring alarm call. The northern grey-headed sparrow is replaced in eastern and southern Africa by very similar birds that are sometimes considered races of this species: Swainson's sparrow, the parrot-billed sparrow, the Swahili sparrow, and the southern grey-headed sparrow. According to phylogenetic studies by Arnaiz-Villena et al., this species is indeed related to the other grey-headed sparrows, and these species together are most closely related within genus Passer to the house sparrow and allies.

The hooded vulture (Necrosyrtes monachus) is an Old World vulture in the order Accipitriformes, which also includes eagles, kites, buzzards and hawks. It is the only member of the genus Necrosyrtes, which is sister to the larger Gyps genus, both of which are a part of the Aegypiinae subfamily of Old World vultures. It is native to sub-Saharan Africa, where it has a widespread distribution with populations in southern, East and West Africa. It is a scruffy-looking, small vulture with dark brown plumage, a long thin bill, bare crown, face and fore-neck, and a downy nape and hind-neck. Its face is usually a light red colour. It typically scavenges on carcasses of wildlife and domestic animals. Although it remains a common species with a stable population in the lower region of Casamance, some areas of The Gambia, and Guinea-Bissau, other regions such as Dakar, Senegal, show more than 85% losses in population over the last 50 years. Threats include poisoning, hunting, loss of habitat and collisions with electricity infrastructure, and the International Union for Conservation of Nature has rated its conservation status as "critically endangered" in their latest assessment (2017). The highest current regional density of hooded vultures is in the western region of The Gambia.

The rock Pigeon is a wild ancestor of all domestic and feral pigeons, inhabiting coasts, cliffs, and caves. Pairs nest in rock crevices, often mating for life. They are known for their ability to fly very long distances to return to their homes, navigating using the sun's position and the earth's magnetic fields. Thanks to this ability, pigeons were used as messengers, particularly during World Wars I and II.

The red-eyed dove is a largish, stocky pigeon, typically 30 cm (12 inches) in length. Its back, wings and tail are pale brown. When flying, it shows blackish flight feathers. The head and underparts are dark vinous-pink, shading to pale grey on the face. There is a black hind neck patch edged with white. The legs and a patch of bare skin around the eye are red. The call is a loud doo-doo-du-du. Sexes are similar, but juveniles are duller than adults, and have scalloping on the body feathers. Red-eyed doves eat grass seeds, grains and other vegetation. They often forage on the ground.

The Schikrasperber or Schikra (Accipiter badius) belongs to the family of the hawk-like (Accipitridae). The species is considered largely unexplored. It originally occurred in western Central Asia, South Kazakhstan and South Asia. Schikras have also been reported on the African continent.

The western plantain-eater (Crinifer piscator), also known as the grey plantain-eater or western grey plantain-eater, is a large member of the turaco family, a group of large arboreal near-passerine birds restricted to Africa. This species is a resident breeder in open woodland habitats in tropical west Africa. It lays two or three eggs in a tree platform nest. These are common, noisy and conspicuous birds, despite lacking the brilliant colours of relatives such as the violet turaco. They are 50 cm long, including a long tail. Their plumage is mainly grey above spotted with brown. The head, erectile crest, neck and breast are brown streaked with silver. The underparts are whitish, heavily streaked with brown. Western plantain-eater has a thick bright yellow bill, and shows a white wing bar in flight. The sexes are identical, but immatures have a black woolly head without silver streaking. This bird is similar to the closely related eastern plantain-eater. The latter species has white tail bars, and lacks the chest bars and dark wing feather shafts of its western relative. This species feeds on fruit, especially figs, seeds and other vegetable matter. Western plantain-eater has a loud cow-cow-cow call, very familiar in west Africa.

This 16 cm long species is mainly pale brown in colour. It has long swept-back wings that resemble a crescent or a boomerang. The body is slender, and the tail is long and deeply forked, although it is usually held closed. The call is a loud, shrill scream. Sexes are similar, and young birds differ mainly in their shorter tails. Palm swifts have very short legs which they use only for clinging to vertical surfaces, since swifts never settle voluntarily on the ground.

The village weaver is a stocky 15–17 cm bird with a strong conical bill and dark reddish eyes. In the northern part of its range, the breeding male has a black head edged by chestnut (typically most distinct on the nape and chest). Towards the southern part of its range, the amount of black and chestnut diminish, and the breeding males of the southernmost subspecies only have a black face and throat, while the nape and crown are yellow. In all subspecies the breeding male has a black bill, black and yellow upperparts and wings, and yellow underparts. The non-breeding male has a yellow head with an olive crown, grey upperparts and whitish underparts. The wings remain yellow and black. The adult female has streaked olive upperparts, yellow and black wings, and pale yellow underparts. Young birds are like the female but browner on the back.

The African Thrush has dark olive-grey upperparts. The underparts show a whitish evenly brown- streaked side throat, the breast is greyish brown and the flanks are pale buff-orange with this colour not extending on to the lower breast, the belly and vent are white. It has a yellow-orange bill. It weighs 46–78g and measures 21–23 cm in length.

Cattle Egrets are short, thick-necked egrets. Their name refers to their preference to follow along with livestock as they forage in fields. Cattle Egrets were native only to Africa until the late 1800s when they somehow made their way throughout the Americas. They can often be found along airport runways waiting for planes to take off and blow insects out of the grass and weeds. They also follow behind farm equipment and do the same thing.

Little swifts are readily identified by their small size. Their wingspan is only 33 cm compared to 42 cm in the case of common swift. Their plumage is black except for a white throat and rump, the white rump patch extending onto the flanks. They have a short square tail, with all rectrices round-tipped. The flight is fluttering like that of a house martin, and the call is a high twittering. Like other swifts they are very short-legged. The legs are used for clinging to vertical surfaces only.

The African harrier-hawk is a medium-sized raptor. The upperparts, head and breast are pale grey. The belly is white with fine dark barring. The broad wings are pale grey with a black trailing edge fringed with a narrow white line. The tail is black with a single broad white band. There is a bare facial patch of variable colour, usually red or yellow. Genders are similar, but young birds have pale brown instead of grey, and dark brown replacing black. An unusual trait of this species is the double-jointed knees it possesses, which enable it to reach into otherwise inaccessible holes and cracks for prey. A comparable leg-structure and behaviour can be found in the Neotropical crane hawk; a case of convergent evolution. The call is a whistled sueee-sueee-sueee.

A small yellow bird with a prominent white eye ring surrounding a dark eye. The underparts and head are yellow, with a black loral stripe, black bill, the flight and tail feathers are brown edged with yellowish olive. Some subspecies are greener, especially those occurring in forest. Juveniles are darker. This bird measures 11·5 cm in length and the weight varies from 6.8 to 14.1g.

This species, like other bee-eaters, is a richly coloured, slender bird. It is predominantly green; its face has blue sides with a black eye stripe, and a yellow and brown throat; the beak is black. It can reach a length of 31 cm (12 in), with the two elongated central tail feathers adding another 7 cm (2.8 in). Sexes are mostly alike but the tail-streamers of the female are shorter. This is a bird which breeds in sub-tropical semi-desert with a few trees, such as acacia. It winters in open woodland or grassland. As the name suggests, bee-eaters predominantly eat insects, especially bees, wasps and hornets, which are caught in the air by sorties from an open perch. However, this species probably takes more dragonflies than any other food item. Its preferred hunting perch is telephone wires if available. Blue-cheeked bee-eaters may nest solitarily or in loose colonies of up to ten birds. They may also nest in colonies with European bee-eaters. The nests are located in sandy banks, embankments, low cliffs or on the shore of the Caspian Sea. They make a relatively long tunnel of 1 to 3 m (3.3–9.8 ft) in length in which the four to eight (usually six or seven), spherical white eggs are laid. Both the male and the female take care of the eggs, although the female alone incubates them at night. Incubation takes 23–26 days. The call sounds 'flatter' and less 'fluty' than the European bee-eater.
