Cameroon offers some of the best and most exciting birding in West and Central Africa. Cameroon boasts of more than 900 species of birds and a lot of them being endemic and near endemic. Cameroon bird habitats in Cameroon are mountain forests, savanna plateaus in the Mid North, Sahel in the Extreme North, the numerous forests and lakes.

In the far north, large concentrations of waterbirds such as White-faced Whistling Duck and Long-tailed Cormorant can be found along with a great variety of raptors. Further south are the transition zones of the Adamawa plateau in the Mbam Djerem National Park and the lowland evergreen forests. In the western part of the country is the Cameroon Mountain Arc with the Afro-tropical mountain vegetation type. This is where the endemic species such as Mount Cameroon Francolin, Mount Kupé Bush-Shrike and Bannerman’s Turaco can be found. There are also several freshwater systems such as River Sanaga and Nyong and a few lakes e.g. Lake Magba and Lake Maga where waterbirds such as cormorants, darters, storks and herons can be seen. The south-west of the country has a 350 km coastline with a marine ecosystem that provides a roosting ground for a host of migratory species.

John James Audubon
(born Jean Rabin; April 26, 1785 – January 27, 1851) was an American ornithologist, naturalist, and painter. He was notable for his extensive studies documenting all types of American birds and for his detailed illustrations that depicted the birds in their natural habitats. His major work, a color-plate book entitled The Birds of America (1827–1839), is considered one of the finest ornithological works ever completed. Audubon identified 25 new species.

Audubon developed his own methods for drawing birds. First, he killed them using fine shot. He then used wires to prop them into a natural position, unlike the common method of many ornithologists, who prepared and stuffed the specimens into a rigid pose. When working on a major specimen like an eagle, he would spend up to four 15-hour days, preparing, studying, and drawing it. His paintings of birds are set true-to-life in their natural habitat. He often portrayed them as if caught in motion, especially feeding or hunting. This was in stark contrast to the stiff representations of birds by his contemporaries, such as Alexander Wilson. Audubon based his paintings on his extensive field observations.

He worked primarily with watercolor early on. He added coloured chalk or pastel to add softness to feathers, especially those of owls and herons. He employed multiple layers of watercolouring, and sometimes used gouache. All species were drawn life size which accounts for the contorted poses of the larger birds as Audubon strove to fit them within the page size. Smaller species were usually placed on branches with berries, fruit, and flowers. He used several birds in a drawing to present all views of anatomy and wings. Larger birds were often placed in their ground habitat or perching on stumps. At times, as with woodpeckers, he combined several species on one page to offer contrasting features. He frequently depicted the birds' nests and eggs, and occasionally natural predators, such as snakes. He usually illustrated male and female variations, and sometimes juveniles. In later drawings, Audubon used assistants to render the habitat for him. In addition to faithful renderings of anatomy, Audubon also employed carefully constructed composition, drama, and slightly exaggerated poses to achieve artistic as well as scientific effects.

The avifauna of Saint Helena Island include a total of 68 species. Only one endemic species survives today, the Saint Helena plover. Several more endemics are extinct and known only from subfossil remains: the Saint Helena petrel, Olson's petrel, Saint Helena shearwater, Saint Helena crake, Saint Helena swamphen, Saint Helena dove, Saint Helena cuckoo and Saint Helena hoopoe. At least five non-endemics have been extirpated from Saint Helena but still occur elsewhere. Nine species have been introduced by humans and formed established breeding populations while many more species were introduced in the past but failed to become established. Of these, 43 species are rare or accidental visitors.

Malachite Kingfisher

Malachite Kingfisher (冠翠鳥)
Namibia (2002)
5th June, 2016. Windhoek Central

Mlachite Kingfisher is a river kingfisher which is widely distributed in Africa south of the Sahara. It is largely resident except for seasonal climate-related movements.

This is a small kingfisher, 13cm in length. The general colour of the upper parts of the adult bird is bright metallic blue. The head has a short crest of black and blue feathers, which gives rise to the scientific name. The face, cheeks, and underparts are rufous and white patches are on the throat and rear neck sides. The bill is black in young birds and reddish-orange in adults; the legs are bright red. Sexes are similar, but juveniles are a duller version of the adult.

This species is common to reeds and aquatic vegetation near slow-moving water or ponds. The flight of the malachite kingfisher is rapid, with the short, rounded wings whirring until they appear a mere blur. It usually flies low over water.

The bird has regular perches or stands from which it fishes. These are usually low over the water. It sits upright, its tail pointed downwards. It drops suddenly with a splash and usually returns at once with a struggling captive.

Large food items are beaten on a bough or rail; small fish and insects are promptly swallowed. A fish is usually lifted and carried by its middle, but its position is changed, sometimes by tossing it into the air, before it is swallowed head downwards. Fish, aquatic insects, and crustaceans are eaten.

The nest is a tunnel in a sandy bank, usually over water. Both birds excavate. Most burrows incline upward before the nesting chamber is reached.

Three or four clutches of three to six round, white eggs are placed on a litter of fish bones and disgorged pellets.

The call of this kingfisher is then a short shrill seek. The breeding song is a chuckling li-cha-cha-chui-chui.

Madagascar Paradise-flycatcher

Madagascar Paradise-flycatcher (馬達加斯加綬帶鳥)
Madagascar (2014)
26th April, 2016. Antananarivo

The Malagasy paradise flycatcher is a medium-sized passerine, measuring 18cm in length and weighing between 12.1 and 12.3g. Males have long tail plumes, which can add as much as 18 cm to their overall length. The female is largely rufous-orange, with a black head and nape. The flight feathers on her wings are black with rufous edges, and she has a thin, light blue eyelid wattle.

This species is a regional endemic found on Madagascar, Mayotte and the Comoros islands. It is common in all native forest types except montane forest, at elevations ranging from sea level to 1,600 m. It also occurs, though less frequently, in other wooded habitats, including plantations, gardens and secondary forest.

Red-footed Booby

Red-footed Booby (紅腳鰹鳥)
Ascension (2016)
22th February, 2016. Georgetown

Red-footed Booby is the smallest member of the booby and gannet family at about 70 cm in length and with a wingspan of up to 1m. The average weight of 490 adults from Christmas Island was 837g. It has red legs, and its bill and throat pouch are coloured pink and blue. This species has several morphs. In the white morph the plumage is mostly white (the head often tinged yellowish) and the flight feathers are black. The black-tailed white morph is similar, but with a black tail, and can easily be confused with the Nazca and masked boobies. The brown morph is overall brown. The white-tailed brown morph is similar, but has a white belly, rump, and tail. The white-headed and white-tailed brown morph has a mostly white body, tail and head, and brown wings and back. The morphs commonly breed together, but in most regions one or two morphs predominates; e.g. at the Galápagos Islands, most belong to the brown morph, though the white morph also occurs.

The sexes are similar, and juveniles are brownish with darker wings, and pale pinkish legs, while chicks are covered in dense white down.

South Africa ranks as one of the top birding destinations in the world, offering an unbeatable combination of variety of birds, well developed transport systems, and a user-friendly and supportive birding tourism industry.

Birders from around the world come to experience both the great variety of typically African birds, migrants, and endemics - those birds found only in South Africa. These birders enjoy excellent birding, whether they are with an organised commercial birding tour or are touring independently.

Of the 850 or so species that have been recorded in South Africa, about 725, or 85%, are resident or annual visitors, and about 50 of these are endemic or near- endemic to South Africa, and can only be seen in the country.

Apart from the resident birds, South Africa hosts a number of African migrants such as cuckoos and kingfishers, as well as birds from the Arctic, Europe, Central Asia, China and Antarctica during the year.

Kenya has the reputation to be the number one country to visit for birds as several World records of twitching (highest bird list seen in a day, in a month...) are from this country. It is undisputably one of the best indeed: birds are numerous, generally not shy and fairly easy to find. Endemic list is not very long (see inset on the right) but Kenya is home of many beautiful and localised species. We describe a selection below: endemics, restricted range species (often shared with Tanzania) and most spectacular Eastern African specialities (often shared with Ethiopia or Somalia). Bird lists are so long that choosing either the bird to list and the photos to illustrate them is difficult!

With their colourful aerobatics, bee-eaters are amongst the most striking of all small birds. As their name implies, bee-eaters live on bees and other flying insects, which they hawk in flight during spectacular aerial pursuits, or snatch from vegetation or the ground. Using their long, sharp, curved bills, the birds will pound stinging insects against a perch to discharge their sting before eating them. Bee-eater species vary significantly in size, yet all are relatively small birds with intricately-coloured plumage. Most bee-eaters are gregarious and roost together, as well as congregating on favourite perches that overlook ideal hunting grounds. Some species nest in large colonies, gathering in spectacular flocks during the breeding season. Some migrate to Namibia from other parts of Africa or Europe and are seen in our country only during the summer months.

Blue-breasted Kingfisher

Blue-breasted Kingfisher (藍胸翡翠)
São Tomé e Príncipe (2015)
3rd February, 2016. São Tomé

The blue-breasted kingfisher is a tree kingfisher which is widely distributed in tropical west Africa. This kingfisher is essentially resident, but retreats from drier savanna areas to wetter habitats in the dry season.

This is a large kingfisher, 25 cm in length. The adult has a bright blue head, back, wing panel and tail. Its underparts are white, but it has a blue breast band. The shoulders are black. The flight of the blue-breasted kingfisher is rapid and direct. The large bill has a red upper mandible and black lower mandible. The legs are bright red.

The blue-breasted kingfisher is a species of a variety of well-wooded habitats. It perches quietly in deep shade whilst seeking food. It is territorial but wary. This species mainly hunts large insects, arthropods, fish and frogs, but will also eat the fruit of the Oil Palm.

It has a striking display in which the wings are spread to show the white linings. The nest is a hole in a tree termite nest. A single clutch of two round white eggs is typical.

Denham's bustard is the largest species in the Neotis genus, although is smaller than the bustards in the Ardeotis genus (as well as the great bustard). The male is 9 to 10 kg and 100–116 cm, the female is much smaller at 3 to 4 kg and 80–87 cm. The back is brown, darker and plainer in the male, and the underparts are white. The neck is pale grey with an orange nape. Its grey crown is bordered with black, and a black line runs through the eye with a white line forming an eyebrow above. The long legs are pale yellow. The wings are strikingly patterned in brown, white and black, the male showing more white in flight than the female or young birds. The long legs are yellowish in color and the bill is whitish horn in colour.

The male inflates his throat when displaying to show a conspicuous balloon of white feathers. This species is usually silent.

Ecotourism

Ecotourism is a form of tourism involving visiting fragile, pristine, and relatively undisturbed natural areas, intended as a low-impact and often small scale alternative to standard commercial (mass) tourism. Its purpose may be to educate the traveler, to provide funds for ecological conservation, to directly benefit the economic development and political empowerment of local communities, or to foster respect for different cultures and for human rights. Since the 1980s ecotourism has been considered a critical endeavor by environmentalists, so that future generations may experience destinations relatively untouched by human intervention. Several university programs use this description as the working definition of ecotourism.

Generally, ecotourism deals with living parts of the natural environments. Ecotourism focuses on socially responsible travel, personal growth, and environmental sustainability. Ecotourism typically involves travel to destinations where flora, fauna, and cultural heritage are the primary attractions. Ecotourism is intended to offer tourists insight into the impact of human beings on the environment, and to foster a greater appreciation of our natural habitats.

Botswana (2015)
10th December, 2015. Gaborone

There are eight species of vulture in Africa of which five are found in Botswana namely Hooded, White-backed, Lappet-faced, White headed and Cape Griffon. Very rare sightings of the Egyptian Vulture have been recorded. Vultures are often the first to arrive at a carcass after a kill or the first to pick up a dead animal. One of the defining images of Africa is that of vultures sitting in trees waiting for a predator to finish feeding.

It is not uncommon to see a number of species of vultures at a carcass at the same time as there is little completion between them due to them feeding on different parts of the carcass. The beaks of each species indicate what they prefer feeding on. For example the small hooked beak of the Hooded Vulture is ideal for small crevasses to pick out titbits, whereas the large beak of the Lappet-faced allows it to feed on tougher, larger pieces.

Vulture cannot fly for long periods but they can soar for hours on thermals, and this is the reason why they only take flight when the day heats up. Vultures are predominantly scavengers but they have been known to kill their own food, with the lappet-faced often killing rodents and hares. Hooded Vultures are known to feed on insects and I have personally watched them feeding on beetles at dung heaps. Vultures were once severely persecuted when it was still mistakenly believed that they killed domestic livestock. Poisoned meat was set out which killed the vultures after they fed on it.

Birds in Guinea

From left to right :
African Fish Eagle (吼海鵰) ; African Jacana (長腳雉鴴)
Guinea (2001)
5th January, 2016. Conakry

African fish eagle is a large bird, and the female, at 3.2-3.6 kg is larger than the male, at 2-2.5 kg. This is typical of sexual dimorphism in birds of prey. Males usually have a wingspan of about 2 m, while females have wingspans of 2.4 m. The body length is 63–75 cm. The adult is very distinctive in appearance with a mostly brown body and large, powerful, black wings. The head, breast, and tail of African fish eagles are snow white, with the exception of the featherless face, which is yellow. The eyes are dark brown in colour. The hook-shaped beak, ideal for a carnivorous lifestyle, is yellow with a black tip. The plumage of the juvenile is brown in colour, and the eyes are paler compared to the adult. The feet have rough soles and are equipped with powerful talons in order to enable the eagle to grasp slippery aquatic prey. While this species mainly subsists on fish, it is opportunistic and may take a wider variety of prey such as waterbirds. Its distinctive cry is, for many, evocative of the spirit or essence of Africa. The call, shriller when uttered by males, is a weee-ah, hyo-hyo or a heee-ah, heeah-heeah.

African jacanas are conspicuous and unmistakable birds. They are about 30 cm long, but females are larger than males. They have chestnut upperparts with black wingtips, rear neck, and eyestripe. The underparts are also chestnut in the adults, only in juveniles they are white with a chestnut belly patch. The blue bill extends up as a coot-like head shield, and the legs and long toes are grey.

Yellow-billed Stork

Yellow-billed Stork (黃嘴䴉鸛)
Gambia (2011)

9th December, 2015. Tranqueras

Yellow-billed stork, sometimes also called the wood stork or wood ibis, is a large African wading stork species in the Ciconiidae family. It is widespread in regions south of the Sahara and also occurs in Madagascar.

The yellow-billed stork is closely related to 3 other species in the Mycteria genus: the American woodstork (Mycteria americana), the milky stork (Mycteria cinerea) and the painted stork (Mycteria leucocephala). It is classified as belonging to one clade with these 3 other species because they all display remarkable homologies in behavior and morphology. In one analytical study of feeding and courtship behaviours of the wood-stork family, MP Kahl attributed the same general ethology to all members of the Mycteria genus, with few species-specific variations. These four species are collectively referred to as the wood-storks, which should not be confused with one alternative common name (wood-stork) for the yellow-billed stork.

Before it was established that the yellow-billed stork was closely related to the American woodstork, the former was classified as belonging to the genus Ibis, together with the milky stork and painted stork. However, the yellow-billed stork has actually long been recognised as a true stork and along with the other 3 related stork species, it should not strictly be called an ibis.

The Endangered Wildlife Trust has been engaged to train staff at South Africa’s international mail centres so that X-ray machine operators know how to identify animals and animal parts in parcels to foreign countries. The contents of all outgoing international mail items are checked by means of X-ray machines.

The elegant grey crowned crane graces many of Africa's wetlands. Threats to their populations include illegal capture for the pet trade and the loss or degradation of suitable wetland habitat, due to an increasing human population and demand for agricultural land and freshwater sources. These birds are listed as endangered.

The Cape parrot is South Africa’s only endemic parrot species and is found in the fragmented southern mistbelt forests. Over the past 150 years, illegal capture for the wild-caught bird trade has reduced the numbers of the global wild population to less than 1600 individuals.

Tunisia is a country much undervisited by birders in the spring. It has plenty to offer both for bird-lovers and history-lovers, plus comfortable tourist resorts. white-headed duck is a small stiff-tailed duck. Adult males have a grey and reddish body, a blue bill and a largely white head with a black cap and neck. Adult females have a grey-brown body with a white face and a darker bill, cap and a cheek stripe. Length is 43–48 cm and weight is 580–750 g. Ferruginous Duck breeding habitat is marshes and lakes with a metre or more water depth. These ducks breed in southern and eastern Europe and southern and western Asia. They are somewhat migratory, and winter farther south and into north Africa. The adult male is a rich chestnut colour with a darker back and a yellow eye. The pure white undertail helps to distinguish this species from the somewhat similar tufted duck. The female is similar but duller, and with a dark eye.

Moussier's Redstart is a small passerine bird in the genus Phoenicurus, formerly classed as a member of the thrush family, but is now classified as an Old World flycatcher. It is an endemic resident breeder in the Atlas Mountains of northwest Africa. Its habitat is open woodland in rocky areas from sea level up to 3000 m altitude in the mountains. Marbled Duck is a medium-sized duck. It used to be included among the dabbling ducks, but is now classed as a diving duck. The scientific name, Marmaronetta angustirostris, comes from the Greek marmaros, marbled and netta, a duck, and Latin angustus, narrow or small and rostris billed.

Common waxbill also known as the St Helena waxbill, is a small passerine bird belonging to the estrildid finch family. It is native to sub-Saharan Africa but has been introduced to many other regions of the world and now has an estimated global extent of occurrence of 10,000,000 km2. It is popular and easy to keep in captivity.

It is a small bird, 11 to 13 centimetres in length with a wingspan of 12 to 14 centimetres and a weight of 7 to 10 grams. It has a slender body with short rounded wings and a long graduated tail. The bright red bill of the adult is the colour of sealing wax giving the bird its name. The plumage is mostly grey-brown, finely barred with dark brown. There is a red stripe through the eye and the cheeks and throat are whitish. There is often a pinkish flush to the underparts and a reddish stripe along the centre of the belly depending on the subspecies. The rump is brown and the tail and vent are dark. Females are similar to the males but are paler with less red on the belly. Juveniles are duller with little or no red on the belly, fainter dark barring and a black bill.

The wildlife of Cape Verde is spread over its archipelago of ten islands and three islets, which all have parks under their jurisdiction by decree promulgated by the Cape Verde government. Located off the west coast of Africa, the total land area of the island nation is 4,564 square kilometres (1,762 sq mi). The wildlife consists of many tropical dry forest and shrub land, endemic flora and fauna, and rare breeding seabirds and plants, which are unique to this group of islands.

Some of the wildlife species of Cape Verde are considered as endemic, evolving over millions of years of isolation; the grey-headed kingfisher survived here on insects in the absence of water in the lands of the islands.

Cape Verde has many species of endemic birds, which are observed by keen ornithologists and bird watchers on the islands. 130 migrant birds are reported to visit the islands, out of which over 40 nest there. The seabirds which breed on the island are: Fea's petrel, frigatebird and red-tailed tropicbird. Four species of birds, (Alexander's swift, the Raso lark, the Cape Verde swamp-warbler and the Iago sparrow) are also endemic here, while the Cape Verde shearwater is a breeding endemic. The endemic and endangered Bourne's heron is sometimes considered a full species. Also common are the greater flamingo and the Egyptian vulture.
