Top 20 Most Common Bird in Luanda

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.

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 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.

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.

This long-winged raptor is predominantly grey or white with black shoulder patches, wing tips and eye stripe. The long falcon-like wings extend beyond the tail when the bird is perched. In flight, the short and square tail is visible and it is not forked as in the typical kites of the genus Milvus. When perched, often on roadside wires, it often adjusts its wings and jerks its tail up and down as if to balance itself. The sexes are alike in plumage. Their large forward-facing eyes placed under a bony shelf that shades them is distinctive; their velvety plumage and zygodactyl feet are characters shared with owls and the genus has been considered as a basal group within the Accipitridae. They are thought to have been adapted for living in savanna habitats where seasonal rodent population peaks occur. Such food resources are also favoured by the owls. The inner vanes of the feathers have velvety barbules. They have a diploid chromosome number of 68 (some older studies claimed 64 for E.c.caeruleus and 66 for E.c.vociferus) with a distinct karyotype with resemblances to the kites and honey buzzards and suggesting a basal position within the diurnal birds of prey.

The grey Heron is a very common species to come across in marine, brackish, and freshwater ecosystems; these habitats must have at least four months of warm weather or else these birds will migrate for new breeding grounds. The grey Heron hunts by wading through shallow waters looking for fish and various invertebrates; their natural diet helps control some aquatic species populations.

The African red-eyed bulbul ranges from 19-21 centimeters (7-8 inches) in length and weighs 30-48 grams (1-1.7 ounces). Its call is a series of loud fluty notes, usually given only by the male.

The white-browed coucal is a medium-sized species growing to 36 to 42 cm (14 to 17 in) in length. The sexes are similar, adults having a blackish crown and nape, a white supercilium, rufous-brown back, chestnut wings, blackish rump and black tail, glossed with green, with a white tip. The underparts are creamy-white, the eyes red, the beak black, and the legs and feet greyish-black or black. Juveniles have rufous streaking on the crown, a faint buff supercilium, barred upper parts and darker underparts.

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 greater blue-eared starling is a 22 cm long, short tailed bird. This starling is glossy blue-green with a purple-blue belly and blue ear patch. Its iris is bright yellow or orange. The sexes are similar, but the juvenile is duller and has blackish brown underparts. The populations from southern Kenya southwards are smaller than northern birds and are sometimes considered to be a separate subspecies, L. c. sycobius. The lesser blue-eared starling is similar to this species, but the blue of the belly does not extend forward of the legs. The greater blue-eared starling has a range of musical or grating calls, but the most familiar is a nasal squee-ar.

Verreaux's eagle is a very large eagle. It measures 75 to 96 cm (30 to 38 in) long from the bill to the tip of the tail, making it the sixth longest eagle in the world. Males can weigh 3 to 4.2 kg (6.6 to 9.3 lb) and the larger females weigh 3.1 to 7 kg (6.8 to 15.4 lb). The average weight is approximately 4.19 kg (9.2 lb), based on the weights of 21 eagles of both sexes. Other reported mean body mass measurements of Verreaux's eagles were lower however, with seven unsexed birds averaging 3.32 kg (7.3 lb), while four unsexed eagles in an additional study averaged 3.72 kg (8.2 lb). In another group of weighed eagles, four females were found to average 4.6 kg (10 lb), which is more than a kilogram more than the average male, It is the seventh or eighth heaviest living eagle in the world. In average mass and overall weight range, if not linear measurements, the Verreaux's is very similar in size to its occasional competitor, the martial eagle, which is regularly titled the largest of the African eagles. It also rivals the martial and golden eagles as the largest extant member of the "booted eagle" clan. It has a wingspan of 1.81 to 2.3 m (5 ft 11 in to 7 ft 7 in). The wing chord of the male is 56.5 to 59.5 cm (22.2 to 23.4 in) and that of the female is 59 to 64 cm (23 to 25 in). Among other standard measurements in the Verreaux's eagles, both sexes measure 27.2 to 36 cm (10.7 to 14.2 in) in tail length and 9.5 to 11 cm (3.7 to 4.3 in) in tarsus length. Other than the female's slight size advantage, adult males and females are physically indistinguishable from each other. Adult Verreaux's eagles are mostly jet-black in color. The yellow coloration of the cere (the bill is gun-metal grey), eye-ring and “eye-brows”, all stand out in contrast to the black plumage. Even more prominent on flying birds when seen from above is the white on the back, rump and upper-tail coverts and part of the scapulars, which forms a V-shaped patch, although this feature is partially obscured in perched birds. Adults also have conspicuous white windows on the wing quills at the carpal joint (at the base of the primaries) when seen flying both from above and below. The bill is stout, the head is prominent on the relatively long neck and the legs are fully feathered. Juvenile and immature plumages differ markedly from the plumage of adults. They are overall a dark brown color. Immatures have a strongly contrasting golden crown and a rufous or ginger nape and mantle. They have small white streaks on the forehead and black on their cheeks. The throat is dark streaked, the lower throat is pale brown and the upper-chest is brown. The rest of the underside is brown but for a blackish-blotched rufous to cream-colored abdomen and lightly marked creamy thighs and legs. The feathers of the upper-tail and upper-wing coverts are brown with white streaks in young birds, while the other tail and wing quills are nearly black. The wing quills when seen from below in flight show considerable whitish mottling, with more extensive white than is typically seen in adult plumages. The immature has a dark brown iris and yellowish feet. Black feathers increase from 2 to 5 years of age amongst a scattering of brown-tipped feathers, though the contrasting creamy trousers are maintained through the 3rd year. By the 4th year, they look dark grey-brown with a buff-patch on the nape and mottling of retained brownish feathers. At the end of the subadult phase at around 5 years of age, the plumage is practically indistinguishable from the adult. Full adult plumage is probably attained in 5 to 6 years. The Verreaux's eagle is essentially unmistakable, especially in adulthood. No other black-colored raptor in its range approaches this species’ large size, nor possesses its distinctive patterns of white. The golden eagle is of similar size or marginally larger size and the two species are the heaviest living Aquila species and measure only marginally less than the slightly lighter-weight Australasian wedge-tailed eagle in total wing and bill-to-tail length. While the juvenile Verreaux's eagle is quite different from the adult's, its plumage is no less distinctive. No other accipitrid shares the mottled brownish body, blackish wings with large white patches or contrasting whitish, rufous and golden color around the head and neck as that of an immature eagle. The flight profile of Verreaux's eagle is also distinctive, as it is the only Aquila species other than the golden eagle to soar in a pronounced dihedral, with the wings held slightly above the back and primaries upturned at the tip to make a V shape. In the Bale Mountains of Ethiopia and possibly in some parts of the Arabian Peninsula and the southwestern edge of the Middle East, the ranges of the golden and Verreaux's eagles overlap, but the golden is a mostly brown bird and shares none of the Verreaux's black plumage. The immature golden eagle has white patches on its underwing as do Verreaux's but they are less extensive than those of the latter species. The wing shape also differs from the golden, as the Verreaux's eagle has very broad outer secondaries and a relatively narrow pinch at the base of the primaries, whereas the tapering of a golden eagle's wing is more gradual. The Verreaux's eagle wings have variously been described as paddle, spoon or leaf shaped. Imperial eagles are another improbable but possible source of confusion, since they too have white markings on their wing coverts, but are totally different in flight profile (much flatter winged) and overall coloration (dark brown).

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 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.

An adult individual is 68 cm (27 in) long with all-white body plumage apart from dark plumes on the rump. Wingspan is 112 to 124 cm (44 to 49 in) and body weight 1.35 to 1.5 kg (3.0 to 3.3 lb). Males are generally slightly larger than females. The bald head and neck, thick curved bill and legs are black. The white wings show a black rear border in flight. The eyes are brown with a dark red orbital ring. Sexes are similar, but juveniles have dirty white plumage, a smaller bill and some feathering on the neck, greenish-brown scapulars and more black on the primary coverts. This bird is usually silent, but occasionally makes puppy-like yelping noises, unlike its vocal relative, the hadada ibis.

They weigh between 11.6 and 21 grams with a length of 13-15 centimeters. Although plumage differs between juveniles, males, and females, cinnamon-breasted buntings can be identified by their striped head and cinnamon brown underparts. Males have black and white stripes whereas the female stripes are less dark and browner in color. The throat patch is uniformly black on males but smaller, grayish, and densely blotched on females. Juveniles are similar to females but with buffier head stripes and a paler, browner throat. After the breeding season, juveniles moult partially and adults moult completely so all primaries and secondaries are the same age. Cinnamon-breasted bunting songs are composed of short, high-pitched, rapid trills. Males are known to have eight distinct songs with 40 discrete syllables. Song similarity decreases with distance between local populations but all end with a characteristic final whistle syllable. Individuals perform songs from elevated positions such as from trees, bushes, or rocks.

The purple-banded sunbird (Cinnyris bifasciatus) is a species of bird in the family Nectariniidae. It is found in Angola, Botswana, Republic of the Congo, Democratic Republic of the Congo, Ethiopia, Gabon, Kenya, Malawi, Mozambique, Namibia, Rwanda, Somalia, South Africa, Swaziland, Tanzania, Uganda, Zambia, and Zimbabwe. The Tsavo sunbird, sometimes lumped with the purple-banded, is here considered a separate species.

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.

This 14–15.5 cm long species has, like some relatives, a short forked tail and long swept-back wings that resemble a crescent or a boomerang. It is entirely dark except for a pale throat patch and a narrow white rump. It is similar to the closely related little swift, but is slimmer, darker and has a more forked tail and a narrower white rump.

The black-headed oriole has a bright yellow body, contrasting black head and flesh-coloured beak. The voice is a liquid-sounding warble, accompanied by imitations and whistles.

This large raptor is commonly known as osprey and can be found in every continent apart from Antarctica. It nests near bodies of water as its diet is made up of mostly fish and hunts with its clear vision that can see objects in the water while flying. The Pandion haliaetus usually mates for life.
