21-12-2023 NGALA LODGE, GAMBIA - COMMON BULBUL (Pycnonotus barbatus)

The common bulbul (Pycnonotus barbatus) is a member of the bulbul family of passerine birds. It is found in north-eastern, northern, western and central Africa.

The common bulbul was originally described in the genus Turdus. Some authorities treat the Somali, Dodson's and dark-capped bulbul as subspecies of the common bulbul. The common bulbul is considered to belong to a superspecies along with the Himalayan bulbul, white-eared bulbul, white-spectacled bulbul, African red-eyed bulbul, and the Cape bulbul. Alternate names for the common bulbul include the black-eyed bulbul, brown bulbul (also used for the Asian red-eyed bulbul), brown-capped geelgat, common garden bulbul, garden bulbul and white-vented bulbul as well as one name used for another species (yellow-vented bulbul).

21-12-2023 NGALA LODGE, GAMBIA - PLAIN TIGER BUTTERFLY (Danaus chrysippus)

Danaus chrysippus, also known as the plain tiger, African queen, or African monarch, is a medium-sized butterfly widespread in Asia, Australia and Africa. It belongs to the Danainae subfamily of the brush-footed butterfly family Nymphalidae. Danainae primarily consume plants in the genus Asclepias, more commonly called milkweed. Milkweed contains toxic compounds, cardenolides, which are often consumed and stored by many butterflies. Because of their emetic properties, the plain tiger is unpalatable to most predators. As a result, its coloration is widely mimicked by other species of butterflies. The plain tiger inhabits a wide variety of habitats, although it is less likely to thrive in jungle-like conditions and is most often found in drier, wide-open areas.

D. chrysippus encompasses three main subspecies: D. c. alcippus, D. c. chrysippus, and D. c. orientis. These subspecies are found concentrated in specific regions within the larger range of the entire species.

The plain tiger is believed to be one of the first butterflies depicted in art. A 3,500-year-old ancient Egyptian fresco in Luxor features the oldest known illustration of this species.

D. chrysippus is a medium-sized butterfly with a wingspan of about 7–8 cm (2.8–3.1 in). The body is black with white spots. The wings are a brownish orange, the upper side brighter and richer than the underside. The apical half of the forewing is black with a white band. The hindwing has three black spots in the center. The wings are bordered in black and outlined with semicircular white spots. This species exhibits slight sexual dimorphism, as the Male has large scent glands on his hindwings, which the female lacks. They appear as a large black spot with a white centre if viewed from the underside

D. chrysippus is a polymorphic species, so the exact coloring and patterning vary within and between populations.

It is similar in appearance to the Indian fritillary (Argynnis hyperbius), which may coexist with it.

21-12-2023 NGALA LODGE, GAMBIA - BLACK KITE (Milvus migrans)

The black kite was described by the French polymath Georges-Louis Leclerc, Comte de Buffon in his Histoire Naturelle des Oiseaux in 1770. The bird was also illustrated in a hand-coloured plate engraved by François-Nicolas Martinet in the Planches Enluminées D'Histoire Naturelle which was produced under the supervision of Edme-Louis Daubenton to accompany Buffon's text. Neither the plate caption nor Buffon's description included a scientific name but in 1783 the Dutch naturalist Pieter Boddaert coined the binomial name Falco migrans in his catalogue of the Planches Enluminées. The type locality is France. The current genus Milvus was erected by the French naturalist Bernard Germain de Lacépède in 1799. Milvus is the Latin word for a red kite; the specific migrans means "migrating" from the Latin migrare "to migrate".

The red kite has been known to hybridize with the black kite (in captivity where both species were kept together, and in the wild on the Cape Verde Islands).

Recent DNA studies suggest that the yellow-billed African races parasitus and aegyptius differ significantly from black kites in the Eurasian clade, and should be considered a separate allopatric species: yellow-billed kite, M. aegyptius. They occur throughout Africa except for the Congo Basin and the Sahara Desert. There have been some suggestions that the black-eared kite (M. m. lineatus) should be elevated to full species status as M. lineatus, but this is not well supported.

Black kites can be distinguished from red kites by the slightly smaller size, less forked tail (visible in flight), and generally dark plumage without any rufous. The sexes are alike though the male is a little smaller and less aggressive (this is the case in most birds of prey). They weigh on average 735 grams. The upper plumage is brown but the head and neck tend to be paler. The patch behind the eye appears darker. The outer flight feathers are black and the feathers have dark cross bars and are mottled at the base. The lower parts of the body are pale brown, becoming lighter towards the chin. The body feathers have dark shafts giving it a streaked appearance. The cere and gape are yellow, but the bill is black (unlike that of the yellow-billed kite). The legs are yellow and the claws are black. They have a distinctive shrill whistle followed by a rapid whinnying call. Males and females have the same plumage but females are longer than males and have a little larger wingspan. Their wingspan is around 150 cm.

The species is found in Europe, Asia, Africa and Australia. The temperate populations of this kite tend to be migratory while the tropical ones are resident. European and central Asian birds (subspecies M. m. migrans and black-eared kite M. m. lineatus, respectively) are migratory, moving to the tropics in winter, but races in warmer regions such as the Indian M. m. govinda (small Indian/pariah kite), or the Australasian M. m. affinis (fork-tailed kite), are resident. In some areas such as in the United Kingdom, the black kite occurs only as a wanderer on migration. These birds are usually of the nominate race, but in November 2006 a juvenile of the eastern lineatus, not previously recorded in western Europe, was found in Lincolnshire.

The species is not found in the Indonesian archipelago between the South East Asian mainland and the Wallace Line.[18] Vagrants, most likely of the black-eared kite, on occasion range far into the Pacific, out to the Hawaiian islands.

In India, the population of M. m. govinda is particularly large especially in areas of high human population. Here the birds avoid heavily forested regions. A survey in 1967 in the 150 square kilometres of the city of New Delhi produced an estimate of about 2200 pairs or roughly 15 per square kilometre. Another survey in 2013 estimated 150 pairs for every 10 square kilometres.

Vagrants from Australia occasionally reach New Zealand, however, only one individual has persisted there (currently ~21 years old).

21-12-2023 NGALA LODGE, GAMBIA - AFRICAN MIGRANT BUTTERFLY (Catopsilia florella)

Catopsilia florella, the African migrant, African emigrant, or common vagrant, is a butterfly of the family Pieridae. It is found in Africa (including Madagascar), Arabia (United Arab Emirates, Saudi Arabia, Oman) and the Canary Islands. Like Catopsilia pomona, this species also has a habit of migration.

Many early authors mentioned the presence of this species in Asia; but those were probably due to confusion arises as Catopsilia pyranthe females exhibit a lot of seasonal variations. Catopsilia florella is not included as a species in India in any recent checklists.

The wingspan is 54–60 mm for males and 56–66 mm for females. Adults are on wing year-round. From South Africa, adults migrate from summer to autumn. They fly in a north-eastern direction.

The larvae feed on Senna occidentalis, Senna septentrionalis, Senna petersiana, Senna italica, Cassia javanica, and Cassia fistula.

21-12-2023 NGALA LODGE, GAMBIA - RAINBOW AGAMA (Agama agama)

The common agama, red-headed rock agama or rainbow agama (Agama agama) is a species of lizard from the family Agamidae found in most of sub-Saharan Africa. To clear up centuries of historical confusion based on Linnaeus and other authors, Wagner et al. designated a neotype (numbered ZFMK 15222) for the species, using a previously described specimen from Cameroon in the collection of the Zoologisches Forschungsmuseum Alexander Koenig in Bonn. The species name was formerly applied to a paraphyletic collection of taxa (a so-called wastebasket); subsequent mitochondrial DNA analysis of various populations indicates they represent separate species. Consequently, three former subspecies A. a. africana, A. a. boensis, and A. a. mucosoensis are now considered separate species, and A. a. savattieri is considered synonymous with A. africana.

The common agama is endemic to countries such as Benin, Burkina Faso, Cameroon, Cape Verde, Chad, Equatorial Guinea, Gabon, The Gambia, Ghana, Guinea, Guinea-Bissau, India, Ivory Coast, Kenya, Liberia, Madagascar, Mali, Mauritania, Niger, Nigeria, Senegal, Sierra Leone, Togo, Tanzania and Uganda. However, it has been introduced through the reptile trade to southern Florida, where it has become extremely common.

Agama agama is well-adapted to arid conditions. These lizards remain active throughout the day except for the hottest hour, when even shaded spots can reach 38 °C (100 °F).

Common agamas are primarily insectivores, but they have been known to eat small mammals and reptiles and vegetation such as flowers, grasses, and fruits. Their diet consists of mainly ants, grasshoppers, beetles and termites. They catch their prey using their tongue, the tip of which is covered by mucous glands that enable the lizard to hold to smaller prey.

21-12-2023 NGALA LODGE, GAMBIA - WHITE CROWNED ROBIN CHAT (Cossypha albicapillus)

The snowy-crowned robin-chat (Cossypha niveicapilla) is a species of bird in the family Muscicapidae. It is also known as the snowy-headed robin-chat. It is found in Angola, Benin, Burkina Faso, Burundi, Cameroon, Central African Republic, Chad, Republic of the Congo, Democratic Republic of the Congo, Ivory Coast, Ethiopia, Gabon, Gambia, Ghana, Guinea, Guinea-Bissau, Kenya, Liberia, Mali, Mauritania, Niger, Nigeria, Rwanda, Senegal, Sierra Leone, Sudan, Tanzania, Togo, and Uganda. Its natural habitats are subtropical or tropical dry forest, subtropical or tropical moist lowland forest, and moist savanna.

Small bird that is brilliant orange in color with a black “mask-cap” on the head. The very top of it’s head has a “snowy crown” that gives the bird its name.

Both female and male Robin Chats are involved in building the nest, but only the female incubates the eggs. Both parents care for the hatchlings.

The Snowy-crowned Robin-chat is very similar to the White-crowned Robin-chat in appearance and will often be mistaken for each other and found together.

It has an orange belly and throat, a blackhead and a distinctive white crown. They have short black beaks and their mantle and wings are slaty with the centre tail being black.

The young Chats are paler in colour so you will know the adults from the siblings.

They feed mainly on insects such as spiders, caterpillars, centipedes and also arthropods. They also love to enjoy a meal of seeds and grains.

This beautiful little bird rarely lives past two years old. 

20-12-2023 NGALA LODGE, GAMBIA - RED EYED DOVE

The red-eyed dove (Streptopelia semitorquata) is a dove that is widespread and common in Sub-Saharan Africa. It has been listed as Least Concern on the IUCN Red List since 2004.

The red-eyed dove is a largish, stocky pigeon, typically 30 cm (12 in) 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.

It is distributed through most of Sub-Saharan Africa, except in desert zones. It is a common, if not abundant, species in most habitats other than deserts. Like several other species in this genus, they are not particularly gregarious and often feed alone or in pairs. They can be found in forests near rivers.

This species builds a stick nest in a tree and lays two white eggs. Its flight is quick, with the regular beats and an occasional sharp flick of the wings, which are characteristic of pigeons in general.

20-12-2023 NGALA LODGE, GAMBIA - COMMON BULBUL (Pycnonotus barbatus)

The common bulbul (Pycnonotus barbatus) is a member of the bulbul family of passerine birds. It is found in north-eastern, northern, western and central Africa.

The bill is fairly short and thin, with a slightly downwards curving 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.

It is a common resident breeder in much of Africa, and it has recently been found breeding in southern Spain at Tarifa. It is found in woodland, coastal bush, forest edges, riverine bush, montane scrub, and in mixed farming habitats. It is also found in exotic thickets, gardens, and parks.

The common bulbul is usually seen in pairs or small groups. It is a conspicuous bird, which tends to sit at the top of a bush. As with other bulbuls they are active and noisy birds. The flight is bouncing and woodpecker-like. The call is a loud doctor-quick doctor-quick be-quick be-quick. 

This species nests throughout the year in the moist tropics, elsewhere it is a more seasonal breeder with a peak in breeding coinciding with the onset of the rainy season. The nest is fairly rigid, thick-walled and cup-shaped. It is usually situated inside the leafy foliage of a small tree or shrub.

Two or three eggs are a typical clutch. Like other bulbuls, it is parasitised by the Jacobin cuckoo.

This species eats fruit, nectar, seeds and insects.

20-12-2023 NEMASU, GAMBIA - FORK TAILED DRONGO (Dicrurus adsimilis)

The fork-tailed drongo (Dicrurus adsimilis), also called the common drongo or African drongo, is a small bird found from the Sahel to South Africa that lives in wooded habitats, particularly woodlands and savannas. They are part of the family Dicruridae and have four recognized subspecies, D. a adsimilis, D. a. apivorus, D. a. fugax and D. a. jubaensis. Like other drongos, the fork-tailed is mostly insectivorous; its diet mainly consists of butterflies, termites, and grasshoppers.

Physically, this species is characterized with a narrow fork-shaped tail, red-brownish eyes, and black plumage throughout all of its body.

The fork-tailed drongo is known for its ability to deceptively mimic other bird alarm calls in order for a certain animal to flee the scene so it can steal their food (kleptoparasitism). They are also notorious for displaying an aggressive and fearless behaviour by attacking and chasing off much larger animals, including birds of prey, when their nest or young are threatened. Due to its extensive range and stable population, the fork-tailed drongo is classified by the IUCN Red List as a least-concern species.

20-12-2023 ALLAHEIN RIVER, SENEGAL - COMMON GREENSHANK (Tringa nebularia)

Its closest relative is the greater yellowlegs, which together with the spotted redshank form a close-knit group. Among them, these three species show all the basic leg and foot colours found in the shanks, demonstrating that this character is paraphyletic. They are also the largest shanks apart from the willet, which is altogether more robustly built. The greater yellowlegs and the common greenshank share a coarse, dark, and fairly crisp breast pattern as well as much black on the shoulders and back in breeding plumage.

This is a subarctic bird, breeding from northern Scotland eastwards across northern Europe and east across the Palearctic. It is a migratory species, wintering in Africa, the Indian subcontinent, and Australasia, usually on fresh water. It breeds on dry ground near marshy areas, laying about four eggs in a ground scrape.

20-12-2023 ALLAHEIN RIVER, SENEGAL - LONG TAILED CORMORANT (Microcarbo africanus)

The reed cormorant (Microcarbo africanus), also known as the long-tailed cormorant, is a bird in the cormorant family Phalacrocoracidae. It breeds in much of Africa south of the Sahara, and Madagascar. It is resident but undertakes some seasonal movements.

This is a small cormorant, 50–55 cm (20–22 in) in overall length with a wingspan of 80–90 cm (31–35 in). It is mainly black, glossed green, in the breeding season. The wing coverts are silvery. It has a longish tail, a short head crest and a red or yellow face patch. The bill is yellow.

The sexes are similar, but non-breeding adults and juveniles are browner, with a white belly. Some southern races retain the crest all year round.

This is a common and widespread species, and is not considered to be threatened. It breeds on freshwater wetlands or quiet coasts.

The reed cormorant can dive to considerable depths, but usually feeds in shallow water. It frequently brings prey to the surface. It takes a wide variety of fish. It prefers small slow-moving fish, and those with long and tapering shapes, such as mormyrids, catfishes, and cichlids. It will less frequently eat soles (which can be important in its diet locally), frogs, aquatic invertebrates, and small birds.

Two to four eggs are laid in a nest in a tree or on the ground, normally hidden from view by long grass.

20-12-2023 ALLAHEIN RIVER, SENEGAL - SENEGAL THICK NEE (Burhinus senegalensis)

The Senegal thick-knee (Burhinus senegalensis) is a stone-curlew, a group of waders in the family Burhinidae. Their vernacular scientific name refers to the prominent joints in the long yellow or greenish legs.

It is a resident breeder in Africa between the Sahara and the equator, and in the Nile valley.

Senegal thick-knees are medium-large waders with strong black and yellow black bills, large yellow eyes — which give them a reptilian appearance — and cryptic plumage. They are similar but slightly smaller than the Eurasian stone-curlew, which winters in Africa. The long dark bill, single black bar on the folded wing, and darker cheek stripe are distinctions from the European species. Senegal thick-knee is striking in flight, with a broad white wing bar. 

20-12-2023 ALLAHEIN RIVER, SENEGAL - WHIMBREL (Numenius phaeopus)

The Eurasian or common whimbrel (Numenius phaeopus), also known as the white-rumped whimbrel in North America, is a wader in the large family Scolopacidae. It is one of the most widespread of the curlews, breeding across much of subarctic Asia and Europe as far south as Scotland. This species and the Hudsonian whimbrel have recently been split, although some taxonomic authorities still consider them to be conspecific.

The Eurasian whimbrel is a fairly large wader, though mid-sized as a member of the curlew genus. It is 37–47 cm (15–19 in) in length, 75–90 cm (30–35 in) in wingspan, and 270–493 g (9.5–17.4 oz; 0.595–1.087 lb) in weight.[14] It is mainly greyish brown, with a white back and rump (subspecies N. p. phaeopus and N. p. alboaxillaris only), and a long curved beak with a kink rather than a smooth curve. The usual call is a rippling whistle, prolonged into a trill for the song. The only similar common species over most of this bird's range are larger curlews. The whimbrel is smaller, has a shorter, decurved bill and has a central crown stripe and strong supercilia.

The whimbrel is a migratory bird wintering on coasts in Africa, and South Asia into Australasia. It is also a coastal bird during migration. It is fairly gregarious outside the breeding season. It is found in Ireland and the United Kingdom, and it breeds in Scotland, particularly around Shetland, Orkney, the Outer Hebrides as well as the mainland at Sutherland and Caithness.

The nest is a bare scrape on tundra or Arctic moorland. Three to five eggs are laid. Adults are very defensive of nesting area and will even attack humans who come too close.

This species feeds by probing soft mud for small invertebrates and by picking small crabs and similar prey off the surface. Before migration, berries become an important part of their diet. It has also been observed taking insects, specifically blue tiger butterflies.

20-12-2023 ALLAHEIN RIVER, SENEGAL - GREY HERON

Grey Herons are unmistakeable: tall, with long legs, a long beak and grey, black and white feathering. They can stand with their neck stretched out, looking for food, or hunched down with their neck bent over their chest.

Eats Lots of fish, but also small birds such as ducklings, small mammals like voles and amphibians. After harvesting, grey herons can sometimes be seen in fields, looking for rodents.

The plumage of the Grey heron is largely ashy-grey above, and greyish-white below with some black on the flanks. Adults have a head and neck white with a broad black supercilium that terminates in the slender, dangling crest, and bluish-black streaks on the front of the neck. The scapular feathers are elongated and the feathers at the base of the neck are also somewhat elongated. Immature birds lack the dark stripe on the head and are generally duller in appearance than adults, with a grey head and neck, and a small, dark grey crest. The pinkish-yellow beak is long, straight, and powerful, and is brighter in color in breeding adults. The iris is yellow and the legs are brown and very long.

20-12-2023 ALLAHEIN RIVER, SENEGAL - OSPREY (Pandion haliaetus)

The osprey is a unique raptor, standing out for its beauty and choice of prey. A piscivore found on all continents on Earth except Antartica, osprey are a single species in their own genus and family. Some of these majestic birds migrate, while those in warm climates stay in place year-round.

Ospreys possess a large, five-foot wingspan and have brown, black, and white coloration throughout their wings and bodies. These birds of prey are noted for their nests which are built on tall, open tree branches or poles near bodies of water. 

Also known as the river hawk, fish hawk, or sea hawk, ospreys are large birds of prey. Ospreys comprise a single species in one family and four subspecies that have some physical variations and are divided by geographic area.

They are noted for their large size, wide wingspan, and a distinctive dark patch on their wings. Ospreys have unique black stripes that run from their beaks across their eyes and down the sides of their heads. They live near water and are unique among raptors for their fish-based diet.

Unlike other raptors, which eat omnivorous diets of whatever’s available, ospreys eat fish exclusively. But they’re not picky about which fish: In North America, they are known to consume 80 freshwater and saltwater species. According to the Cornell Lab of Ornithology, an osprey’s typical prey will measure between 6 and 13 inches in length and weigh less than a pound, though exceptions have been documented. In 2020, beachgoers in South Carolina captured video of an osprey apprehending what looks like a small shark (above).

Their fishy diet generally supplies all of the hydration they need.

To locate prey, ospreys glide high in the air over a body of shallow water, looking for fish with their keen vision. When they spot one, they will dive toward the surface, extending their legs and talons forward just before hitting the water. Once the fish is caught, the bird flaps its long wings to lift itself up. Unlike eagles or hawks, ospreys will always catch and hold its prey head-first to reduce wind resistance as they fly.

Ospreys build large nests, called eyries, on top of trees, telephone poles, buoys, or human-made nesting platforms near wetlands. The nests consist of sticks, reeds, and grasses, and those located near towns or cities might also include nylon netting, plastic bags, or other garbage. Once they successfully lay and raise eggs in their nest, ospreys will return to it year after year, adding additional sticks each time. But if an osprey pair fails to raise chicks for some reason, they’ll build a new nest—dubbed a “frustration eyrie”—nearby.

20-12-2023 ALLAHEIN RIVER, SENEGAL - GREY HEADED GULL (Chroicocephalus cirrocephalus)

The grey-headed gull (Chroicocephalus cirrocephalus), also known as the gray-hooded gull, is a small species of gull which breeds patchily in South America and Africa south of the Sahara. It is not truly migratory, but is more widespread in winter. This species has occurred as a rare vagrant to North America, Italy and Spain. As is the case with many gulls, it has traditionally been placed in the genus Larus.

This locally abundant gull breeds in large colonies in reedbeds and marshes, and lays two or three eggs in a nest, which can be on the ground or floating. Like most gulls, it is highly gregarious in winter, both when feeding and in evening roosts. Although it is predominantly coastal or estuarine, it is not a pelagic species, and is rarely seen at sea far from land.

Flocks numbering hundreds or thousands of these gulls can form when the feeding conditions are appropriate.

The grey-headed gull is slightly larger than the black-headed gull at 42 cm length. The summer adult has a pale gray head, a gray body, darker in tone than the black-headed, and red bill and legs. The black tips to the primary wing feathers have conspicuous white "mirrors". The underwing is dark gray with black wingtips. The gray hood is lost in winter, leaving just dark streaks.

Sexes are similar. The South American race is slightly larger and paler-backed than the African subspecies.

20-12-2023 ALLAHEIN RIVER, SENEGAL - PINK BACKED PELICAN (Pelecanus rufescens)

The pink-backed pelican (Pelecanus rufescens) is a bird of the pelican family. It is a resident breeder in the swamps and shallow lakes of Africa and southern Arabia; it has also apparently been extirpated from Madagascar.

It is a relatively small pelican, although by no means is it a small bird. Its length is from 125 to 155 cm (49 to 61 in), wingspan is 2.15–2.9 m (7.1–9.5 ft) and body mass is from 4 to 7 kg (8.8 to 15.4 lb). The bill is 30 to 38 cm (12 to 15 in) in length. The plumage is grey and white, with a pinkish hue on the back occasionally apparent (never in the deep pink of a flamingo). The top of the bill is yellow and the pouch is usually greyish. Breeding adults have long feather plumes on the head.

It shares its habitat with the great white pelican, which is generally larger and has white instead of greyish plumage.

20-12-2023 ALLAHEIN RIVER, SENEGAL - PIED KINGFISHER (Ceryle rudis)

The pied kingfisher (Ceryle rudis) is a species of water kingfisher widely distributed across Africa and Asia. Originally described by Carl Linnaeus in 1758, it has five recognised subspecies. Its black and white plumage and crest, as well as its habit of hovering over clear lakes and rivers before diving for fish, make it distinctive. Males have a double band across the breast, while females have a single broken breast band. They are usually found in pairs or small family groups. When perched, they often bob their head and flick up their tail.

The pied kingfisher was one of the many bird species originally described by Linnaeus in the landmark 1758 10th edition of his Systema Naturae, who noted that it lived in Persia and Egypt. He named it Alcedo rudis. The German naturalist Friedrich Boie erected the genus Ceryle in 1828. The name is from classical Greek kērulos, an unidentified and probably mythical bird mentioned by Aristotle and other authors. The specific epithet rudis is Latin for "wild" or "rude".

The pied kingfisher is the only member of the genus Ceryle. Molecular analysis shows it is an early offshoot of the lineage that gave rise to American kingfishers of the genus Chloroceryle. The pied kingfisher was initially believed to be descended from an ancestral American green kingfisher which crossed the Atlantic Ocean about one million years ago. A more recent suggestion is that the pied kingfisher and the American green kingfishers are derived from an Old World species, with the pied kingfisher or its ancestor losing the metallic colouration afterwards.

This is a medium-sized kingfisher, about 25 cm (9.8 in) long with a white with a black mask, a white supercilium and black breast bands. The crest is neat and the upperparts are barred in black. Several subspecies are recognized within the broad distribution. The nominate race is found in sub-Saharan Africa, extending into West Asia. The subspecies syriacus is a larger northern bird similar to the nominate subspecies (following Bergmann's rule). Subspecies leucomelanura is found from Afghanistan east into India, Thailand and Southeast Asia. The subspecies travancoreensis of the Western Ghats is darker with the white reduced. The subspecies C. r. insignis is found in Hainan and southeastern China and has a much larger bill. Males have a narrow second breast-band while females have a single broken breast band.

When perched the pied kingfisher often bobs its heads up and down and will sometimes raise its tail and flick it downwards. It calls often with sharp chirruk chirruk notes. Unlike some kingfishers, it is quite gregarious, and forms large roosts at night.

This kingfisher feeds mainly on fish, although it will take crustaceans and large aquatic insects such as dragonfly larvae. It usually hunts by hovering over the water to detect prey, before diving vertically bill-first to capture fish. When not foraging, it has a straight rapid flight and have been observed flying at speeds approaching 50 km/h. In Lake Victoria in East Africa, the introduction of the Nile perch reduced the availability of haplochromine cichlids which were formerly the preferred prey of these birds.

It can consume prey without returning to a perch, often manipulating the subject with its bill and swallowing in flight, and so can hunt over large water bodies or in estuaries that lack perches required by other kingfishers.

The breeding season in India is February to April. Its nest is a hole excavated in a vertical mud bank about five feet above water. The nest tunnel is four to five feet deep and ends in a chamber. Several birds may nest in the same vicinity. The usual clutch is three to six white eggs. The pied kingfisher sometimes reproduces cooperatively, with young non-breeding birds from an earlier brood assisting parents or even unrelated older birds. In India, nestlings have been found to be prone to maggot infestations (probably by Protocalliphora sp.) and in some areas to leeches. Nest holes may sometimes be used for roosting.

In 1947, British zoologist Hugh B. Cott noticed while skinning birds that hornets were attracted to certain birds but avoided the flesh of pied kingfishers. This led to a comparative study of edibility of birds and he suggested that more conspicuously plumaged birds may be less palatable. This suggestion was, however, not supported by a subsequent reanalysis of his data.

If you evoke a kingfisher image, you see its unmistakable dagger beak. Well, the pied kingfisher is even more recognizable due to its simple black and white colors and its comparatively larger size.

It is one of the most largely populated species, ranking in the top three. These high numbers could be due to its specialized hunting abilities, which no other kingfisher species possesses.

But sometimes, it can be tricky to identify gender in birds. Luckily pied kingfishers perpetuate gender stereotypes.

The male kingfisher has two black bands across the chest, which look similar to a bowtie. The female, on the other hand, has a singular gorget often split down the middle, which has a startling likeness to a bikini!

The distinctive hunting technique of pied kingfishers has earned the species a few records. Not only are they the largest hovering bird. But they are also the only kingfishers with the ability to perform a figure of eight wing stroke. 

20-12-2023 ALLAHEIN RIVER, SENEGAL - WESTERN REEF HERON

The western reef heron (Egretta gularis ), also called the western reef egret, is a medium-sized heron found in southern Europe, Africa and parts of Asia. It has a mainly coastal distribution and occurs in several plumage forms: a slaty-grey plumage in which it can only be confused with the rather uncommon dark morph of the Little egret (Egretta garzetta ); a white form which can look very similar to the little egret although the bill tends to be paler and larger and the black form with white throat E. g. gularis of West Africa. There are also differences in size, structure and foraging behaviour. There have been suggestions that the species hybridizes with the Little Egret, and based on this, some authors treat schistacea and gularis as subspecies of Egretta garzetta. Works that consider the Western Reef Heron as a valid species include the nominate gularis and schistacea as subspecies.

It occurs mainly on the coasts in tropical west Africa, the Red Sea, the Persian Gulf (Iran) extending east to India. It also occurs in the Lakshadweep Islands and Sri Lanka where breeding was once recorded at Chilaw. The nominate subspecies breeds in west Africa from Mauritania to Gabon. Birds may also be found off the mainland such as in the Canary Islands. Small numbers breed in Spain. Subspecies schistacea is found from the Red Sea coast east round the Indian coast. Breeding colonies are known from the east coast of India around Pulicat Lake. They occasionally occur further inland.

This bird has two plumage colour forms. There is an all-white morph and a dark grey morph; morphs can also occur with intermediate shades of grey which may be related to age or particoloured in grey and white. The white morph is similar in general appearance to the little egret, but has a larger yellower bill, extended yellow on thicker legs, and when foraging tends to be very active, sometimes also moving its wing or using it to shade the water surface. The grey morph has a whitish throat and is unlikely to be confused with any other species within the range of this egret with beak and legs similar to that of the white morph. During the breeding season the legs and facial skin are reddish. Breeding birds have two long feathers on the sides of the nape. The nominate subspecies gularis has a range from West Africa to Gabon, with some birds breeding in southern Europe. Subspecies schistacea (Hemprich & Ehrenberg, 1828) breeds from the Persian Gulf along the coast of India to the east of the India Peninsula. The bill of gularis is more pointed while schistacea has the larger bill especially towards the base. The form on the eastern coast of South Africa is usually separated as the dimorphic egret Egretta dimorpha. The dark and white morph is thought to be controlled by a single allele with the dark character being incompletely dominant over the gene for white. 

20-12-2023 ALLAHEIN RIVER, SENEGAL - GREAT EGRET (Ardea alba)

The great egret (Ardea alba), also known as the common egret, large egret, or (in the Old World) great white egret or great white heron is a large, widely distributed egret. The four subspecies are found in Asia, Africa, the Americas, and southern Europe. Recently it is also spreading to more northern areas of Europe. Distributed across most of the tropical and warmer temperate regions of the world, it builds tree nests in colonies close to water.

The great egret is generally a very successful species with a large and expanding range, occurring worldwide in temperate and tropical habitats. It is ubiquitous across the Sun Belt of the United States and in the Neotropics.
