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 - REED (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.

20-12-2023 KARTONG, GAMBIA - DANCING AMBER BUTTERFLY (Telchinia serena)

Acraea serena, the dancing acraea, is a butterfly of the family Nymphalidae. It is found throughout Africa south of the Sahara. It is the most common of the Acraea, from Dakar to Fort-Dauphin and from Yemen to the Cape.

This is the type species of the old genus Telchinia, which may warrant re-separation from Acraea. Formerly, A. serena was often misidentified as Acraea eponina (small orange acraea) or Acraea terpsicore (tawny coaster).

It is very likely that the butterfly's black-spotted orange markings are a sign of unpalatability and it may well form part of a mimicry ring with Erikssonia edgei.

"A. terpsichore" misident. A. serena is a common species and very variable, especially in the female; it occurs everywhere in the region except in Arabia and forms some not quite sharply defined races. In the type-form the sexes are quite similar and above coloured and marked almost exactly as in ventura (56 a); the subapical band of the forewing is completely separated from the red-yellow basal half and is red-yellow or sometimes in the female whitish; both wings above and beneath with distinct yellow marginal spots; the basal area of the hindwing beneath without red streaks or only in 1 c and the cell with a red streak between the black dots; the marginal band always without red stripes on the interneural folds. In female-ab. janisca Godt. (the females 56 a are transitional to janisca) the red-yellow colour is replaced by dark grey and the subapical band of the forewing is usually white. - subserena Smith is similar to the form buxtoni; both wings above with sharply defined, deep black marginal bands, which on the forewing are unicolorous but on the hindwing have small light marginal spots; fore wing beneath with sharply defined, light-spotted, black marginal band; hindwing beneath with a few black dots in the basal part and with sharply defined black, light-spotted marginal band; subapical band of the forewing completely united with the basal area, en closing a quadrate black spot at the end of the cell. Sierra Leone. - rougeti Guer. (= eliana Strand) has like the type-form, large light marginal spots on both wings above, but differs in the forewing having beneath at the distal margin only sharply prominent black vein-ends and no proximally defined light marginal spots, the light ground-colour reaching the distal margin between the veins without interruption; the light subapical band of the forewing is sometimes separate, sometimes united with the light basal part; basally straight and cut off almost vertically to the costal margin. 

Was described from specimens from Abyssinia, but occurs almost identically also in South and East Africa and on Madagascar. Females with almost transparent, whitish ground-colour on both wings may be called female-ab. manjaca Bdv. They occur especially on Madagascar - buxtoni Btlr. (56 a, as rougeti) closely approximates to rougeti, only differing in having the light marginal spots on the upperside of the forewing smaller or indistinct and the marginal band of the forewing deeper black and irregularly defined proximally; the subapical band of the forewing joined to the light basal half at vein 4. South and East Africa. In ab. melas Oberth. the wings are unicolorous black with an irregular white spot instead of the subapical band of the forewing and beneath only relieved with yellowish at the distal margin and at the base. - ab. connexa Thur. has the distal black dot in the cell of the hindwing joined to the median dots. German East Africa. - ab. excentrica Thur. differs in having discal dots 3 to 6 on the underside of the hindwing placed much nearer to the distal margin than usual, elongated and sometimes almost reaching the marginal band. German East Africa. - ab. toka Strand closely approximates to typical rougeti, only differing materially in having the proximal boundary-line of the marginal band on the underside of the hindwing black instead of reddish. Abyssinia. - ab. intermediana Strand is another nearly allied aberration to rougeti, distinguished by the strong development of the red basal streak and the somewhat broader marginal band on the hindwing beneath. German East Africa. How Strand, who has access to the extensive material of the Berlin Museum, could regard intermediana and eliana (rougeti ) as independent species, is difficult to explain, as they obviously intergrade without sharp delimitation into the other terpsichore forms and are only characterized by trifling differences. - ab. contraria Strand is described as follows: "The red spots in the marginal band on the upper surface of both wings are only quite weakly indicated, hence at a cursory glance the band appears unicolorous; on the underside of the hindwing some of the black spots in the basal area are smaller, namely those of the distal and inner-marginal rows, and in addition the distal round spot in the cell is so small as to be almost obsolete. In the distal transverse row only 5 spots are present, namely those in cellules 1 b, 1 c, 2, 4 and 7, of which the one in cellule 4 is punctiform. The bordering of the black marginal spots is so broad that the black interspaces are as broad, as the spots themselves. Beyond the black transverse spot on the underside of the forewing, which as usual is confluent with the costal margin, there is no further, smaller, black spot". German East Africa. Evidently an extreme aberration of buxtoni. - ab. venturina Thur. forms a transition to the following race; the underside of the hindwing has between the basal and discal dots red streaks in 1 c, 7 and in the cell; the marginal band is, however of uniform breadth with marginal spots of almost equal size, which at their proximal end have at most a reddish dot or spot.

20-12-2023 KARTONG, GAMBIA - WEST AFRICAN CROCODILE (Crocodylus suchus)

The muzzle is short and thick. The distance between the eyes and the tip of the muzzle is 1.5 to 2 times longer than the width of the muzzle at the level of the front edge of the eyes (1.2 to 1.5 times in case of juveniles). The coloration is generally brown to olive. Juveniles are paler, with black bandings, especially on the tail.Like all other species of crocodiles, the West African crocodile's eyes reflect light at night allowing it to be spotted easily through a flashlight. It is found to be active day and night. It can stay submerged underwater for more than 30 minutes, and can reach speeds of up to 30 km/h (19 mph) in short bursts.

On land, it is often observed basking motionless in the sun, often with its mouth agape. 

20-12-2023 KARTONG, GAMBIA - BLUE CHEEKED BEE-EATER (Merops persicus)

The blue-cheeked bee-eater (Merops persicus) is a near passerine bird in the bee-eater family, Meropidae. The genus name Merops is Ancient Greek for "bee-eater", and persicus is Latin for "Persian".

It breeds in Northern Africa, and the Middle East from eastern Turkey to Kazakhstan and India. It is generally strongly migratory, wintering in tropical Africa, although some populations breed and live year-round in the Sahel. This species occurs as a rare vagrant north of its breeding range, with most vagrants occurring in Italy and Greece.

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 (3–10 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.
