20-12-2023 KARTONG, GAMBIA - 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.

This species has a preference for dry open habitats with some bare ground, preferably near water. It lays two blotchy light brown eggs on a ground scrape. It is most active at dawn and dusk. The song is a loud pi-pi-pi-pi-pi-pi-pi.

Food is insects, crustaceans and other invertebrates. It will also take other small prey.

19-12-2023 NGALA LODGE, GAMBIA - BLACK BILLED WOOD DOVE (Turtur abyssinicus)

The black-billed wood dove (Turtur abyssinicus) is a pigeon which is a widespread resident breeding bird in a belt across Africa just south of the Sahara Desert.

This species is abundant in near desert, scrub and savannah. It builds a stick nest in a tree, often an acacia, and lays two cream-colored eggs. Its flight is quick, with the regular beats and an occasional sharp flick of the wings which are characteristic of pigeons in general, and it tends to stay quite low.

Black-billed wood dove is a small plump pigeon, typically 20 cm in length. Its back, hindneck, wings and tail are pale grey brown, and the folded wings have dark metallic patches. There are two blackish bands on the back. The forehead, crown and nape are bluish grey, fading to whitish on the face. The underparts are pinkish, becoming whiter on the belly.

The bill of this dove is, of course, black. When flying, black-billed wood dove shows chestnut in the underwing. The call is a persistent fluted coo-coo-cu-coo. Sexes are similar, but immatures are duller than adults, scaly below, and lack the wing spots.

Black-billed wood doves eat grass and other small seeds. They are quite terrestrial, and usually forage on the ground.

They are not very gregarious, but form large flocks at waterholes.

Though they are classified as Least Concern in the IUCN, their population has decreased significantly since 2004. 

19-12-2023 NGALA LODGE, GAMBIA - BEAUTIFUL SUNBIRD

The beautiful sunbird (Cinnyris pulchella), formerly placed in the genus Nectarinia, is a sunbird. It is native to tropical Africa, its range extending from Senegal and Guinea in the west to Sudan, South Sudan, Ethiopia, Tanzania and Kenya in the east.

Beautiful sunbirds are tiny, only 10 cm (4 in) long, although the breeding male's long tail adds another 5 cm (2 in). They have medium-length thin down-curved bills and brush-tipped tubular tongues, both of which are adaptations to their nectar feeding. The male has a black head, bright metallic green upper parts, scarlet breast bordered with yellow and black belly. The central feathers of the teal are greatly elongated. The female is brown above with yellowish underparts.

19-12-2023 NGALA LODGE, GAMBIA - PIAPIAC (Ptilostomus afer)

The piapiac (Ptilostomus afer) is an African bird in the crow family, and is the only member of the genus Ptilostomus. It is most closely related to the Central Asian ground jays.

In size it is a little smaller and slimmer than the European magpie (Pica pica) though the bill is relatively thicker. It is 35–42 cm (14–17 in) in length and weighs 121–130 g (4.3–4.6 oz). The overall colouring is black with the feathers quite silky in texture and having a purplish gloss in good light. The base of the tail tends to be more brown in colour than the rest of the body. Unusual for a passerine it has 10 rather than 12 tail feathers. The nasal plumes are somewhat upturned on top of the bill but fully cover the nostrils. The bill itself is black in the adult but partly reddish-pink towards the base in juvenile specimens. The bird's legs and feet are black and the iris is variable, but tends towards violet, purple or mauve with a bluish-purple outer ring. The voice is usually described as a shrill squeaking often with the jackdaw-like overtones. There is also a croaking alarm call given in anger where the head bobs.

The range of the species is the tropical equatorial region of central Africa from Senegal on the west coast, eastwards in a broad band to Sudan and southern Ethiopia. Within this range, its favoured habitat is towards more open country of cultivated land with fields and pasture and small associated towns and villages.

Food is obtained in flocks of ten or more birds moving together on the ground including insects and other invertebrates but will take a degree of carrion, possibly attracted as much by the associated insects this attracts as much as the meat itself. Some fruit is also taken in trees with the oily fruit of the oil palm Elaeis guineensis a favourite. Able to run fast with some agility, it tends to hop at slower speed and will catch insects disturbed by the feet of cattle, sometimes hitching a ride on their backs and darting out to catch the prey.

The piapiac often nests in a palm tree, but other nesting sites are also used. Strips of palm leaf and grass stems are cemented together with mud and lined with palm fibre to form a cup, in which three to seven eggs are laid between March and April. Piapiac eggs are very pale blue, or greenish-blue with a few brown blotches.

20-12-2023 KARTONG, GAMBIA - SPUR WINGED LAPWING (Vanellus spinosus)

The spur-winged lapwing or spur-winged plover (Vanellus spinosus) is a lapwing species, one of a group of largish waders in the family Charadriidae.

It is one of several species of wader supposed to be the "trochilus" bird said by Herodotus to have been involved in an unattested cleaning symbiosis with the Nile crocodile.

The spur-winged lapwing breeds around the eastern Mediterranean, and in a wide band from sub-Saharan west Africa to Arabia. The Greek and Turkish breeders are migratory, but other populations are resident. The species is declining in its northern range, but is abundant in much of tropical Africa, being seen at almost any wetland habitat in its range. The spur-winged lapwing is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds applies.

In eastern and southern Africa the species has seen a range increase, entering Zambia for the first time in 1999 and spreading south and west.

These are conspicuous and unmistakable birds. They are medium-large waders with black crown, chest, foreneck stripe and tail. The face, the rest of the neck and belly are white and the wings and back are light brown. The bill and legs are black. Its striking appearance is supplemented by its noisy nature, with a loud did-he-do-it call. The bird's common name refers to a small claw or spur hidden in each of its wings.

This species has a preference for marshes and similar freshwater wetland habitats. The food of the spur-winged lapwing is insects and other invertebrates, which are picked from the ground.

It lays four blotchy yellowish eggs on a ground scrape. The spur-winged lapwing is known to sometimes use the wing-claws in an attack on animals and, rarely, people, who get too close to the birds' exposed offspring.

21-12-2023 NGALA LODGE, GAMBIA - LAUGHING DOVE (Streptopelia senegalensis)

The laughing dove (Spilopelia senegalensis) is a small pigeon that is a resident breeder in Africa, the Middle East, South Asia, and Western Australia where it has established itself in the wild after being released from Perth Zoo in 1898. This small long-tailed dove is found in dry scrub and semi-desert habitats where pairs can often be seen feeding on the ground. It is closely related to the spotted dove (Spilopelia chinensis) which is distinguished by a white and black chequered necklace. Other names include laughing turtle dove, palm dove and Senegal dove while in Asia the name little brown dove is often used.

The laughing dove is a long-tailed, slim pigeon, typically 25 cm (9.8 in) in length. It is pinkish brown on the underside with a lilac tinged head and neck. The head and underparts are pinkish, shading to buff on the lower abdomen. A chequered rufous and grey patch is found on the sides of the neck of adults and is made up of split feathers. The upper parts are brownish with a bluish-grey band along the wing. The back is uniform and dull brown in the South Asian population. The African populations S. s. senegalensis and S. s. phoenicophila have a bluish grey rump and upper tail coverts but differ in the shades of the neck and wing feathers while S. s. aegyptiaca is larger and the head and nape are vinous and upper wing coverts are rufous. The tail is graduated and the outer feathers are tipped in white. The sexes are indistinguishable in the field. Young birds lack the chequered neck markings. The legs are red. The populations vary slightly in plumage with those from more arid zones being paler. Abnormal leucistic plumages have been noted.

The chuckling call is a low rolling croo-doo-doo-doo-doo with a rising and falling amplitude.

It is a common and widespread species in scrub, dry farmland, and in areas of human habitation, often becoming very tame. Its range includes much of Sub-Saharan Africa, Saudi Arabia, Iran, Iraq, Afghanistan, Pakistan, and India. It is also found in Cyprus, Israel, Lebanon, Syria, Jordan, the UAE, and Turkey (these populations may be derived from human introductions). They are mostly sedentary but some populations may make movements. Birds ringed in Gujarat have been recovered 200 km north in Pakistan and exhausted birds have been recorded landing on ships in the Arabian Sea. The species (thought to belong to the nominate population) was introduced to Perth in 1889 and has become established around Western Australia. Birds that land on ships may be introduced to new regions.

The species is usually seen in pairs or small parties and only rarely in larger groups. Larger groups are formed especially when drinking at waterholes in arid regions. Small numbers assemble on trees near waterholes before flying to the water's edge where they are able to suck up water like other members of the pigeon family. Laughing doves eat the fallen seeds, mainly of grasses, other vegetable matter and small ground insects such as termites and beetles. They are fairly terrestrial, foraging on the ground in grasslands and cultivation. Their flight is quick and direct with the regular beats and an occasional sharp flick of the wings characteristic of pigeons in general.

The male in courtship display follows the female with head bobbing displays while cooing. The male pecks its folded wings in "displacement-preening" to solicit copulation from the female. A female accepts by crouching and begging for food. The male may indulge in courtship feeding before mounting and copulating. Pairs may preen each other. Males may also launch into the air with wing clapping above their backs and then glide down in a gentle arc when displaying. The species has a spread out breeding season in Africa. Almost year-round in Malawi and Türkiye; and mainly May to November in Zimbabwe, February to June in Egypt and Tunisia. In Australia the main breeding season is September to November. The nest is a very flimsy platform of twigs built in a low bush and sometimes in crevices or under the eaves of houses. Both parents build the nest with males bringing the twigs which are then placed by the female. Two eggs are laid within an interval of a day between them and both parents take part in building the nest, incubating and feeding the young. Males spend more time incubating the nest during the day. The eggs are incubated after the second egg is laid and the eggs hatch after about 13 to 15 days. Nesting adults may feign injury to distract and draw predators away from the nest. Multiple broods may be raised by the same pair in the same nest. Seven broods by the same pair have been noted in Türkiye.[20] Initially the altricial hatchlings are fed with regurgitated crop-milk, a secretion from the lining of the crop of parent birds. The young fledge and leave the nest after about 14 to 16 days. The Jacobin cuckoo sometimes lays its egg in the nests of the laughing dove in Africa.

 

20-12-2023 ALLAHEIN RIVER, SENEGAL - GOLIATH HERON (Ardea goliath)

The Goliath heron (Ardea goliath), also known as the giant heron, is a very large wading bird of the heron family, Ardeidae. It is found in sub-Saharan Africa, with smaller, declining numbers in Southwest and South Asia.

This is the world's largest living heron (the extinct Bennu heron was larger). The height of the goliath heron is 120–152 cm (3 ft 11 in – 5 ft 0 in), the wingspan is 185–230 cm (6 ft 1 in – 7 ft 7 in) and the weight is 4–5 kg (8.8–11.0 lb).[4][5] The tarsus measures from 21.2 to 25.5 cm (8.3 to 10.0 in) and the wing chord averages around 60.7 cm (23.9 in) in length. The culmen measures from 18 to 20 cm (7.1 to 7.9 in), while the bill from the gape measures around 24 cm (9.4 in). In flight it has a slow and rather ponderous look and, unlike some other herons, its legs are not held horizontally. Male and female look similar, with an overall covering of slate gray and chestnut feathers. The head and its bushy crest, face, back and sides of the neck are chestnut. The chin, throat, foreneck and upper breast are white, with black streaks across the foreneck and upper breast. The lower breast and belly are buff with black streaks. The back and upper wings are slate-grey, with a chestnut shoulder patch at the bend of the wings when they're closed. The under-wing is pale chestnut. The upper mandible is black and the lores and orbital areas are yellow with a greenish tinge. The eyes are yellow while the legs and feet are black. Juveniles look similar to adults, but are paler. The only heron with somewhat similarly-colorful plumage characteristics, the widespread purple heron, is much smaller than the Goliath. Despite the shared plumage characteristics with the purple species, the closest extant relatives of the Goliath are considered to be the great-billed and the white-bellied herons of Southern Asia. Due to their large size, this species trio is sometimes referred to as the "giant herons".

The Goliath heron has a distinct deep bark, often described as kowoork, audible from a distances of up to 2 km. A disturbance call (arrk), sharper and higher, can also occasionally be heard. A huh-huh is given during the crouched stage, while a krooo may be heard with the neck extended. Organ-like duetting has been reported at nest sites but has not been confirmed.

The Goliath heron is very aquatic, even by heron standards, rarely venturing far from a water source and preferring to fly along waterways rather than move over land. Important habitats can include lakes, swamps, mangrove wetlands, reefs with few cool water, sometimes river deltas. It typically is found in shallows, though can be observed near deep water over dense water vegetation. Goliath herons can even be found in small watering holes. They have ranged in elevation from sea level to 2,100 m (6,900 ft). They tend to prefer pristine wetlands and generally avoid areas where human disturbances are a regular occurrence.

Goliath herons are solitary foragers and are highly territorial towards other Goliaths entering their feeding territories. On occasions, two may be seen together but these are most likely to be a breeding pair or immatures. A diurnal and often rather inactive feeder, this heron often hunts by standing in the shallows, intently watching the water at its feet. This is a typical feeding method among large Ardea herons and it can forage in deeper waters than most due to its larger size. It may also perch on heavy floating vegetation, in order to prevent water from rippling around them. As prey appears, the heron rapidly spears it with open mandibles, often spearing both mandibles through the fish's body, and then swallows it whole. It is possible that the bill is used in a lure-like fashion occasionally, attracting fish to the immobile, large object submerged in the water. The handling period is long, with herons often placing their struggling prey on floating vegetation while preparing to swallow it. Due to its generally slow movements and handling time, the Goliath is frequently vulnerable to kleptoparasitism. In Africa, African fish eagles frequently pirate food caught by Goliaths, although other large birds such as saddle-billed storks and pelicans may also steal their prey.

Prey almost entirely consists of fish. The Goliath heron specializes in relatively large fish, with an average prey weight range of 50–980 g (0.11–2.16 lb), averaging 500–600 g (1.1–1.3 lb) and length of 30 cm (12 in). Fish exceeding 1 kg (2.2 lb) are usually rejected, though there is a report that the heron managed to swallow 1.4 kg (3.1 lb) fish.[9][10] Small fish are generally ignored and the average Goliath catches around 2 or 3 fish a day. Breams, mullet, tilapia and carp have locally been recorded as preferred species. Any other small animals that they come across may be eaten, including frogs, prawns, small mammals, lizards, snakes, insects and even carrion.

Its breeding season coincides generally with the start of the rainy season, which is around November to March. In some areas, breeding is year around, with no discernable peak season. Breeding may not occur every year. Fairly adaptable in their nesting site selection, Goliath herons generally prefer to nest on islands or islands of vegetation. The birds may abandon a nesting site if the island becomes attached to the mainland. Lakes or other large bodies of water usually hold colonies. They nest fairly low in variously sedge, reeds, bushes, trees or even on rocks or large tree stumps. The nesting dispersal seems highly variable as everything from a solitary pair (with no other Goliath nests anywhere near) to fairly large colonies have been observed, with no seeming local geographical preferences. Occasionally, they may join mixed-species colonies including other heron species, cormorants, darters, ibises and gulls. The breeding displays are not well known and may be subdued, due in part to breeding pairs possibly reunited year after year. The nests are large but often flimsy (depending on available vegetation around the nesting site), often measuring around 1 to 1.5 m (3.3 to 4.9 ft) in diameter.

Eggs are pale blue, averaging 72 by 54 mm (2.8 by 2.1 in) and weighing around 108 g (3.8 oz). The clutch size can range from 2 to 5 (usually 3 or 4). Incubation lasts 24 to 30 days. Although they can sometimes replace clutches, often only around 25% of eggs succeed in hatching due to various environmental conditions or predation. The young are fed by regurgitation in the nest and, after a few weeks, can bill jab and practice defensive postures against each other. At around five weeks they leave the nest completely. The parents continue to tend to them for variously 40 to 80 days. Around 62% of fledglings who successfully leave the nest survive to adulthood. Locally, the white-tailed eagle and the African fish eagle may be a predator in colonies. Despite their ponderous movements, Goliath herons can think quickly and often take flight before danger approaches. Also, due to its size and formidable bill, the full-grown Goliath heron may not have any regular predators.

 

20-12-2023 ALLAHEIN RIVER, SENEGAL - WEST AFRICAN CROCODILE (Crocodylus suchus)

The West African crocodile, desert crocodile, or sacred crocodile (Crocodylus suchus) is a species of crocodile related to — and often confused with — the larger and more aggressive Nile crocodile (C. niloticus).

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.

Compared to the Nile crocodile, which can grow over 5 m (16 ft 5 in) in length, the West African crocodile is smaller. It typically grows between 2 and 3 m (6 ft 7 in and 9 ft 10 in) in length, with an occasional male growing over 4 m (13 ft 1 in) in rare cases.[12] Adults weigh between 90 and 250 kg (200 and 550 lb), with particularly large male specimens exceeding 300 kg (660 lb) in weight.

The West African crocodile inhabits much of West and Central Africa, ranging east to South Sudan and Uganda, and south to Democratic Republic of the Congo (in all three countries it may come into contact with Nile crocodiles). Other countries where it is found include Mauritania, Benin, Liberia, Guinea-Bissau, Nigeria, Niger, Cameroon, Chad, Sierra Leone, Central African Republic, Equatorial Guinea, Senegal, Mali, Guinea, Gambia, Burkina Faso, Ghana, Gabon, Togo, Ivory Coast and Republic of Congo. As late as the 1920s, museums continued to obtain West African crocodile specimens from the southern Nile, but today the species has disappeared from this river.

In Mauritania it has adapted to the arid desert environment of the Sahara–Sahel by staying in caves or burrows in a state of aestivation during the driest periods, leading to the alternative common name desert crocodile. When it rains, these desert crocodiles gather at gueltas. In much of its range, the West African crocodile may come into contact with other crocodile species and there appears to be a level of habitat segregation between them. The Nile crocodile typically prefers large seasonal rivers in savannah or grassland, while the West African crocodile generally prefers lagoons and wetlands in forested regions, at least where the two species may come into contact. The details of this probable segregations remains to be confirmed for certain. In a study of habitat use by the three crocodile species in Liberia (West African, slender-snouted and dwarf), it was found that the West African crocodile typically occupied larger, more open waterways consisting of river basins and mangrove swamps, and was the species most tolerant of brackish waters. In comparison, the slender-snouted crocodile typically occupies rivers within forest interiors, while dwarf crocodiles are distributed in smaller rivers (mainly tributaries), streams and brooks also within forested areas.

20-12-2023 KARTONG, GAMBIA - AFRICAN HARRIER HAWK (JUVENILE) (Polyboroides typus)

The African harrier-hawk, harrier hawk or gymnogene (Polyboroides typus) is a bird of prey. It is about 60–66 centimetres (24–26 in) in length. It breeds in most of Africa south of the Sahara. The only other member of the genus is the allopatric Madagascar harrier-hawk (Polyboroides radiatus).

The African harrier-hawk is a medium-sized raptor. The upperparts, head and breast are pale grey. The belly is white with fine dark barring. The broad wings are pale grey with a black trailing edge fringed with a narrow white line. The tail is black with a single broad white band. There is a bare facial patch of variable colour, usually red or yellow. Sexes are similar, but young birds have pale brown instead of grey, and dark brown replacing black. An unusual trait of this species is the double-jointed ankles it possesses, which enable it to reach into otherwise inaccessible holes and cracks for prey. A comparable leg-structure and behaviour can be found in the Neotropical crane hawk as well as the extinct Australian Pengana; a case of convergent evolution.

The call is a whistled sueee-sueee-sueee.

20-12-2023 KARTONG, GAMBIA - RED BILLED FIREFINCH (MALE) (Lagonosticta senegala)

The red-billed firefinch or Senegal firefinch (Lagonosticta senegala) is a small seed-eating bird in the family Estrildidae. This is a resident breeding bird in most of Sub-Saharan Africa with an estimated global extent of occurrence of 10,000,000 km2. It was introduced to Egypt, but the population there has become extinct. It was also introduced to southern Algeria where it is currently expanding northward.

The red-billed firefinch is 10 cm (3.9 in) in length. The adult male has entirely scarlet plumage apart from brown wings. The bill is pink, and there is a yellow eye-ring. Females have uniformly brown upperparts and buff underparts. There is a small red patch in front of both eyes, with the bill also being pink.

20-12-2023 KARTONG, GAMBIA - BLUE BELLIED ROLLER (Coracias cyanogaster)

The blue-bellied roller (Coracias cyanogaster) is a member of the roller family of birds which breeds across Africa in a narrow belt from Senegal to northeast Democratic Republic of the Congo. It is resident, apart from some local seasonal movements, in mature moist savannah dominated by Isoberlinia trees.

The blue-bellied roller was given the binomial name Coracias cyanogaster in 1816 by the French naturalist Georges Cuvier based on "Le Rollier à ventre bleu" that had been described and illustrated by François Levaillant in 1806. The specific epithet combines the Ancient Greek kuanos meaning "dark-blue" with gastēr meaning "belly". Levaillant mistaken believed that the specimen had been collected on the island of Java. The species is resident in West-Africa and the type location was later designated as Senegal. The species is monotypic: no subspecies are recognised.

20-12-2023 NEMASI, GAMBIA - MELAGASI GRASS YELLOW BUTTERFLY (Eurema floricola)

Eurema floricola, the Malagasy grass yellow, is a butterfly in the family Pieridae. It is found in Sierra Leone, Ivory Coast, Ghana, Nigeria, the Democratic Republic of Congo, Burundi, Kenya, Tanzania, Zambia and on Madagascar, the Comoros, Mauritius, Réunion and the Seychelles. Its habitat consists of the forest/savanna transition zone.

The larvae feed on Desmanthus virgatus, Caesalpinia bonducella, Leucaena glauca, Mimosa and Entada species.

20-12-2023 NEMASU, GAMBIA - RAINBOW 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.

Its size varies from 13 to 30 cm (5.1 to 11.8 in) in total length. Males are typically 7.5 to 12 cm (3.0 to 4.7 in) longer than the average female. The agama lizard can be identified by having a white underside, brown back limbs and a tail with a light stripe down the middle. The stripe on the tail typically possesses about six to seven dark patches along its side. Females, adolescents and subordinate males have an olive green head, while a dominant male has a blue body and yellow tail.

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.

Male agamas are territorial and must fight other males to claim their space. Agamas live in social groups including a lead male, about half a dozen females, and subordinate males. Subordinate males can only gain their own group if they eliminate the existing lead male (the "cock") or establish a colony outside all other cocks' territory. Only the cock is allowed to mate with the females. The center of a cock's territory is usually marked by the presence of a physical object, such as a tree or boulder, on which the lizards congregate. In urban areas, fights between males are more common because space is at a higher premium.

Females are sexually mature at 14–18 months, while males take 2 years. Agama agama tends to reproduce during the wet season, but can also reproduce in areas that receive constant rainfall. After fertilization and when she is ready to lay, the female will dig a hole 5 cm (2 in) deep with her snout and claws in damp, sandy soil that is covered with grasses or other plants and which receives sunlight during most of the day. Once finished, the female will lay a clutch of 5–7 ellipsoidal eggs that hatch within a period of 8–10 weeks.

The sex of common agama embryos are determined by temperature, so all male eggs experienced a temperature of 29 °C (84 °F) while female eggs are in the 26–27 °C (79–81 °F) range. After hatching, the offspring will measure about 3.7 cm (1.5 in) snout to vent, plus their 7.5 cm (3.0 in) tail.

20-12-2023 NEMASU, GAMBIA - DIVERSE WHITE BUTTERFLY (Appias epaphia)

Appias epaphia, the diverse white or African albatross, is a butterfly of the family Pieridae.  It is found in Africa, south of the Sahara. The habitat consists of forests and heavy woodland.

The wingspan is 40–50 millimetres (1.6–2.0 in). Adults are on wing year-round, but mainly from March to May in southern Africa.

The larvae feed on Capparis species (including Capparis sepiaria), Maerua racemulosa, and Boscia albitrunca.

20-12-2023 NEMASU, GAMBIA - COMMON SMOKY BLUE BUTTERFLY (Euchrysops malathana)

Euchrysops malathana, the common smoky blue or smoky bean Cupid, is a butterfly of the family Lycaenidae. It is found in south-western Arabia and Africa, south of the Sahara including Madagascar.

The wingspan is 22–30 mm for males and 23–31 mm for females. Adults are on wing year-round, with a peak from December to May in South Africa.[2]

The larvae feed on Sphenostylis angustifolius, Medicago, Psidium, Canavalia and Vigna species (including V. triloba and V. unguiculata).

19-12-2023 NGALA LODGE, GAMBIA - LAUGHING DOVE (Streptopelia senegalensis)

The laughing dove (Spilopelia senegalensis) is a small pigeon that is a resident breeder in Africa, the Middle East, South Asia, and Western Australia where it has established itself in the wild after being released from Perth Zoo in 1898. This small long-tailed dove is found in dry scrub and semi-desert habitats where pairs can often be seen feeding on the ground. It is closely related to the spotted dove (Spilopelia chinensis) which is distinguished by a white and black chequered necklace. Other names include laughing turtle dove, palm dove and Senegal dove while in Asia the name little brown dove is often used.

18-12-2023 BARCELONA, SPAIN - MONK PARAKEET (Myiopsitta monachus)

 The monk parakeet (Myiopsitta monachus), also known as the monk parrot or Quaker parrot, is a species of true parrot in the family Psittacidae. It is a small, bright-green parrot with a greyish breast and greenish-yellow abdomen. Its average lifespan is 20–30 years. It originates from the temperate to subtropical areas of South America. Self-sustaining feral populations occur in many places, mainly in areas of similar climate in North America and Europe.

19-12-2023 NGALA LODGE, GAMBIA - LONG TAILED GLOSSY STARLING (Lamprotornis caudatus)

The long-tailed glossy starling (Lamprotornis caudatus) is a member of the starling family of birds. It is a resident breeder in tropical Africa from Senegal east to Sudan.

This common passerine is typically found in open woodland and cultivation. The long-tailed glossy starling builds a nest in a hole. The normal clutch is two to four eggs.

This ubiquitous bird is gregarious and noisy, with a harsh grating call.

The adults of these 54 cm (21 in) long birds have metallic green upperparts, violet underparts and a 34 cm (13 in) long purple tail. The face is black with a yellow eye. The sexes are similar, but juveniles are duller, with a brownish tone to the plumage.

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.

19-12-2023 NGALA LODGE, GAMBIA - BLACK KITE (Milvus migrans)

The black kite (Milvus migrans) is a medium-sized bird of prey in the family Accipitridae, which also includes many other diurnal raptors. It is thought to be the world's most abundant species of Accipitridae, although some populations have experienced dramatic declines or fluctuations. Current global population estimates run up to 6 million individuals.

Unlike others of the group, black kites are opportunistic hunters and are more likely to scavenge. They spend much time soaring and gliding in thermals in search of food. Their angled wing and distinctive forked tail make them easy to identify. They are also vociferous with a shrill whinnying call.

The black kite is widely distributed through the temperate and tropical parts of Eurasia and parts of Australasia and Oceania, with the temperate region populations tending to be migratory. Several subspecies are recognized and formerly had their own English names. The European populations are small, but the South Asian population is very large.

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. 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). 

19-12-2023 NGALA LODGE, GAMBIA - PIED CROW (Corvus albus)

The pied crow (Corvus albus) is a widely distributed African bird species in the crow genus of the family Corvidae.

Structurally, the pied crow is better thought of as a small crow-sized raven, especially as it can hybridise with the Somali crow (dwarf raven) where their ranges meet in the Horn of Africa. Its behaviour, though, is more typical of the Eurasian carrion crows, and it may be a modern link (along with the Somali crow) between the Eurasian crows and the common raven.

It is about the size of the European carrion crow or a little larger (46–50 cm in length), but has a proportionately larger bill, slightly longer tail and wings, and longer legs. As its name suggests, its glossy black head and neck are interrupted by a large area of white feathering from the shoulders down to the lower breast. The tail, bill, and wings are black, too. The eyes are dark brown. The white plumage of immature birds is often mixed with black. It resembles the white-necked and thick-billed ravens, but has a much smaller bill.

This species, Africa's most widespread member of the genus Corvus, occurs from sub-Saharan Africa, specifically Nigeria, Ghana, Senegal, Sudan, Somalia, Eritrea, Zambia, Botswana, Mozambique and Zimbabwe, south to the Cape of Good Hope and on the large island of Madagascar, the Comoros Islands, Aldabra, Assumption Island, Cosmoledo, Astove Island, Zanzibar, Pemba, and Fernando Po. It inhabits mainly open country with villages and towns nearby. It does not occur in the equatorial rainforest region. It is rarely seen very far from human habitation, though it is not as tied to the urban way of life as the house crow (Corvus splendens) of Asia, and may be encountered far from human habitation in Eritrea.

19-12-2023 NGALA LODGE, GAMBIA - BROWN BABBLER (Turdoides plebejus)

The brown babbler (Turdoides plebejus) is a species of bird in the family Leiothrichidae. It is predominantly found in West Africa, but ranging from the Gambia to Kenya. The species is common across its range. The species is also known as the Sudan babbler.

The brown babbler was described in 1828 by Philipp Jakob Cretzschmar from a specimen collected in the Kordofan Province of Sudan. He originally placed it in the bulbul genus Ixos. The species is closely related to and forms a superspecies with the white-headed babbler of eastern Sudan, Ethiopia and Eritrea, and the arrow-marked babbler of central and southern Africa. The Old World babbler family Timaliidae has been the subject of much research and has been split by some taxonomic authorities. This move would place this species with the laughingthrushes in the family Leiothrichidae.

There are three recognised subspecies, the nominate race, platycirca and cincera. A fourth subspecies, uamensis, is synonymized with cincera.

The brown babbler is a medium-sized Turdoides babbler, measuring 22–25 centimetres (8.7–9.8 in) in length and weighs around 52–80 grams (1.8–2.8 oz). The plumage is grey-brown with a white-streaked throat and breast and a scaled head. The wings are bronze-brown, the bill black and the legs dusky or slaty black. The iris of the eyes are yellow. The sexes are alike, and juvenile birds are like the adults but with plainer and browner plumage and brown irises.

The brown babbler inhabits the broad band of the Sahel between the Sahara Desert and the tropical forests of Western Africa, from southern Mauritania, Senegal and the Gambia to southern Sudan, Uganda and western Kenya. The species lives in open savanna, wooded grasslands, riparian habitat in drier areas, degraded cultivation, farmlands, parks and gardens. The species is common across its range and readily lives in human-modified habitat and is not considered threatened with extinction.

The species is mostly sedentary (non-migratory), but is thought to make some seasonal movements based upon local conditions related to the rainy seasons. In central Burkina Faso it is observed more frequently during the rainy season, and it has also been observed to be erratically absent or present in the Kampala region of Uganda.

The brown babbler consumes a variety of insects including ants, beetles, termites, and praying mantises, as well as other invertebrates, berries, and fruit. It will also opportunistically take carrion. They generally forage on the ground and in family parties of up to 14 individuals.

19-12-2023 NGALA LODGE, GAMBIA - YELLOW BILLED SHRIKE (Lanius corvinus)

The yellow-billed shrike (Lanius corvinus) is a large passerine bird in the shrike family. It is sometimes known as the long-tailed shrike, but this is to be discouraged, since it invites confusion with the long-tailed shrike, Lanius schach, of tropical southern Asia. The yellow-billed shrike is a common resident breeding bird in tropical Africa from Senegal eastwards to Uganda and locally in westernmost Kenya. It frequents forest and other habitats with trees.

The yellow-billed shrike is 32 cm (13 in) with a long, graduating tail and short wings. The adult has mottled brown upperparts and streaked buff underparts. It has a brown eye mask and a rufous wing patch, and the bill is yellow. Sexes are largely similar, but females have maroon patches on the flanks, while males have rufous parches; these patches are only visible when the bird is in flight, displaying, engaging in territorial disputes, or preening. Immature birds show buff fringes to the wing feathers. The legs and feet are black, and the beak is yellow, even in juveniles. It is a noisy bird, with harsh swee-swee and dreee-too calls.

The species is resident in tropical Africa, south of the Sahara and north of the equator, but is not present in the Horn of Africa. It is present in Benin, Burkina Faso, Cameroon, Central African Republic, Chad, Congo, the Democratic Republic of Congo, Côte d'Ivoire, Gambia, Ghana, Guinea, Guinea-Bissau, Kenya, Mali, Mauritania, Niger, Nigeria, Senegal, Sierra Leone, South Sudan, Sudan, Togo, and Uganda. It makes localised movements, but these have been little studied.

This is a conspicuous and gregarious bird and a cooperative breeder, always seen in groups, often lined up on telephone wires. The nest is a cup structure in a bush or tree into which four or five eggs are laid. Only one female in a group breeds at a given time, with other members providing protection and food.

The yellow-billed shrike feeds on insects, which it locates from prominent look-out perches in trees, wires, or posts. They also sometimes eat small frogs, reptiles, and mice, but are not known to eat other birds or to form larders.

16-12-2023 MONTE CORONA, VALENCIA - SARDINIAN WARBLER (MALE) (Sylvia melanocephala)

The Sardinian warbler (Curruca melanocephala) is a common and widespread typical warbler from the Mediterranean region. Like most Curruca species, it has distinct male and female plumages. The adult male has a grey back, whitish underparts, black head, white throat and red eyes. Plumages are somewhat variable even in the same locality, with the intensity of a reddish hue on upper- and/or underside that varies from absent to (in some subspecies) pronounced. The female is mainly brown above and buff below, with a grey head. The Sardinian warbler's song is fast and rattling, and is very characteristic of the Mediterranean areas where this bird breeds.

It breeds in the southernmost areas of Europe and just into Asia in Turkey and the eastern end of the Mediterranean. This small passerine bird, unlike most "warblers", is not particularly migratory, but some birds winter in North Africa, and it occurs as a vagrant well away from the breeding range, as far as Great Britain.

This is a bird of open country and cultivation, with bushes for nesting. The nest is built in low shrub or brambles, and 3-6 eggs are laid. Like most "warblers", it is insectivorous, but will also take berries and other soft fruit.
