Top 20 Most Common Bird in Congo (Brazzaville)

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.

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.

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.

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 speckled mousebird is about 35 cm (14 inches) long, with the tail comprising approximately half the length, and weighs about 57 grams (2 oz). It is well-named, because it is dull-mousy brown in overall color on the back and on the head (including a prominent crest). The bill is black on the upper part and is a pinkish color on the lower part. The rare white-headed mousebird can be confused with this species, but the differently colored mandibles and the lack of a bare grey orbital patch render the Speckled species distinctive. The speckled mousebird is not known for its voice, as songbirds are, although it is a noisy creature. They make a warbling tsu-tsu call while in flight, and are known for their tisk-tisk alarm call while in flight.

The bronze mannikin is one of the smallest munia species, measuring 9–10 cm in length and weighing 7–12 grams. The adult is a compact bird with a short black tail, and stubby black and pale grey (not distinctly bluish) mandibles. It is black to brownish black on the head, chin, throat and center of the chest, with some purple-green iridescence on the face and sides of the breast. It has greyish brown upper parts and white underparts with irregular barring on the flanks and rump. A small green iridescent patch is present on the outer scapular feathers, besides, especially in the western race, the sides of the lower breast. Wing coverts and remiges are bordered in a paler or warmer tone. The sexes are similar. Immature birds are dun brown above with buff head and underpart plumage. They moult into full adult plumage by age six months, when the males also begin to sing and exhibit breeding behaviour.

This is a medium-sized kingfisher, 23 cm (9.1 in) in length. The adult has a bright blue back, wing panel and tail. Its head, neck and underparts are white, and its shoulders are black. The flight of the woodland kingfisher is rapid and direct. The large bill has a red upper mandible and black lower mandible. The legs and feet are dark grey. Some birds may have greyish heads, causing confusion with mangrove kingfisher. However, the lores are dark, creating a dark stripe through the eye (the stripe does not extend through the eye in mangrove kingfisher), and the underwing, primaries and secondaries are black with white underwing coverts (there is a black carpal patch on the white coverts in mangrove kingfisher). The inner webs of the base of the flight feathers are white, creating an indistinct white wingbar (white completely absent from wings in mangrove kingfisher). The breast is white (tends to be much greyer in mangrove kingfisher). The sexes are similar, but juveniles are duller than adults and have a brown bill. The call of this noisy kingfisher is a loud trill sounding like a nail run down the teeth of a comb.

Just as its name implies, the little house Sparrow socializes with humans more than any other bird species. Able to adapt and thrive in almost any habitat, excluding the extremes such as deserts and mountain peaks, this species was once restricted only to North Africa and Eurasia but now is found across the globe. Unfortunately, this opportunistic eater is not completely harmless—it can cause considerable damage to crops.

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 grey parrot is a medium-sized, predominantly grey, black-billed parrot. Its typical weight is 400 g (0.88 lb), with an approximate length of 33 cm (13 in), and a wingspan of 46–52 cm (18–20 in). It has darker grey than its body over the head and both wings. The head and body feathers have slight white edges. The tail feathers are red. Due to selection by parrot breeders, some grey parrots are partly or completely red. Both sexes appear similar. The colouration of juveniles is similar to that of adults, but typically, their eyes are dark grey to black, in comparison to the yellow irises around dark eyes of the adult birds, and their undertail coverts are tinged with grey. Adults weigh 418–526 g (0.922–1.160 lb). Grey parrots may live for 40–60 years in captivity, although their mean lifespan in the wild appears to be shorter — approximately 23 years.

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.

The African openbill is a stork 80–94 cm long with a weight of 1–1.3 kg. Its adult plumage is generally dark overall, with glossy green, brown, and purple on the mantle and breast. The bill is brownish and notably large. The legs are black and the eye is grey. The juvenile plumage is more dull and brown, with areas of pale feather tips.

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 little bee-eater (Merops pusillus) is a near passerine bird species in the bee-eater family, Meropidae. They are residents in much of Sub-Saharan Africa. They should not be confused with the little green bee-eater, Merops orientalis. Migration is limited to seasonal movements depending on rainfall patterns. Members of this species, like other bee-eaters, are rich and brightly-coloured slender birds. They have green upper parts, yellow throats, black gorgets, and rich brown upper breasts fading to buffish ochre on the belly. Their wings are green and brown, and their beaks are black. They reach a length of 15–17 cm, which makes them the smallest African bee-eater. Sexes are alike. Often silent, their call is a soft "seep." These are abundant and tame birds, familiar throughout their range. There have been estimated to be between 60-80 million little bee-eaters. They breed in open country with bushes, preferably near water. Just as the name suggests, bee-eaters predominantly eat insects, especially bees, wasps and hornets, who are caught in the air by sorties from an open perch. This species often hunts from low perches, maybe only a metre or less high. Before eating their meal, a bee-eater removes the sting by repeatedly hitting the insect on a hard surface. Unlike most bee-eaters, these are solitary nesters, making a tunnel in sandy banks, or sometimes in the entrance to an Aardvark den. They lay 4 to 6 spherical white eggs. Both the male and the female take care of the eggs. These birds roost communally, lined up on a tree branch.

The blue waxbill has powder-blue face, breast, rump, and flanks with pale brown upperparts. The female is paler than the male and the blue is confined to the rump, tail, head, and upper breast, with the rest of the underparts being buffy brown. They measure 12–13 cm in length.

The slender-billed weaver (Ploceus pelzelni) is a species of bird in the weaver family, Ploceidae. It is found in central and western Africa.

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.

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.

These tall birds are quite distinctive with their bright white feathers, black legs, and orange beaks. Great Egrets live near both fresh and saltwater, nesting high in trees to protect their eggs from predatory mammals. They are colonial nesters, living in large groups (colonies), and they find the majority of their food in the nearest body of water.

The male is mainly glossy black with white streaking, but females and immature birds are browner. The African darter differs in appearance from the American darter most recognisably by its thin white lateral neck stripe against a rufous background colour. The pointed bill should prevent confusion with cormorants. It is an 80 cm long cormorant-like fish-eating species with a very long neck, like other anhingas.
