27-12-2023 KOTU CREEK, GAMBIA - LONG TAILED CORMORANT (JUVENILE) (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).[7] 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.

27-12-2023 KOTU CREEK, GAMBIA - SENEGAL THICK NEE (Burhinus senegalensis)

 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.

1-1-2024 NGALA LODGE, GAMBIA - GREEN MONKEY (Chlorocebus sabaeus)

The green monkey (Chlorocebus sabaeus), also known as the sabaeus monkey, is an Old World monkey with golden-green fur and pale hands and feet. The tip of the tail is golden yellow as are the backs of the thighs and cheek whiskers. It does not have a distinguishing band of fur on the brow, like other Chlorocebus species, and males have a pale blue scrotum. Some authorities consider this and all of the members of the genus Chlorocebus to be a single widespread species, C. aethiops.[citation needed]

The green monkey is a sexually dimorphic species, with males typically being slightly larger than females. Wild adult males weigh between 3.9 and 8.0 kg (8.6 and 17.6 lb) and measure between 420 and 600 mm (1.38 and 1.97 ft), while the females usually weigh between 3.4 and 5.3 kg (7.5 and 11.7 lb) and measure between 300 and 495 mm (0.984 and 1.624 ft).

The green monkey can be found in a wide range of wooded habitats, ranging from very dry Sahel woodland to the edge of rainforests. It is also commonly seen in coastal regions, where known to feed on seashore foods such as crabs. It also takes a wide variety of other foods, including fruits and invertebrates.

The green monkey is found in West Africa from Senegal and The Gambia to the Volta River. It has been introduced to the Cape Verde islands off north-western Africa (islands of Santiago and Brava only) as early as the second half of the 16th century, and the West Indian islands of Saint Kitts, Nevis, Saint Martin, and Barbados, having been introduced in the late 17th century by slave ships coming from West Africa. A small colony descended from 20th century zoo escapees exists in Broward County, Florida.

As other members of the genus Chlorocebus, the green monkey is highly social and usually seen in groups. They usually live in groups of 7 up to 80 individuals. Within these groups, there is distinct social hierarchy evidenced by grooming behaviors and gender relationships.

Green monkeys are known to communicate both verbally and non-verbally. They have distinct calls which they use to warn others in the group of predators, and even have specific calls for specific predators. Body language, such as the display of brightly colored genitalia, is also used to communicate danger, but can also be used as a way of establishing dominance. It has also been documented that green monkeys may use facial expressions to express their emotional state.

 Green monkeys live in a polygynous society, revolving around the alpha males. The alpha males have control over social interactions and mating between other males and females in the group.

These monkeys are seasonal breeders, breeding during the April to June months (October and November in the Nyes area North West of Thies), during which rainfall is the heaviest. It is during these rainy seasons that fruit is most abundant, so it is speculated that green monkeys schedule their breeding around this time, when resources are most abundant. They breed about once a year, with males reaching sexual maturity in five years, females in two. Despite infant mortality being fairly high, at roughly 57%, green monkeys are known to be heavily invested in their offspring, with mothers taking care of their young for about a year before letting them venture out as individual adults.

27-12-2023 KOTU CREEK, GAMBIA - 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.

Like all egrets, it is a member of the heron family, Ardeidae. Traditionally classified with the storks in the Ciconiiformes, the Ardeidae are closer relatives of pelicans and belong in the Pelecaniformes, instead. The great egret—unlike the typical egrets—does not belong to the genus Egretta, but together with the great herons is today placed in Ardea. In the past, however, it was sometimes placed in Egretta or separated in a monotypic genus Casmerodius.

The Old World population is often referred to as the "great white egret". This species is sometimes confused with the great white heron of the Caribbean, which is a white morph of the closely related great blue heron.

27-12-2023 KOTU CREEK, GAMBIA - 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.

27-12-2023 KOTU CREEK, GAMBIA - AFRICAN DARTER (Anhinga rufa)

The African darter (Anhinga rufa), sometimes called the snakebird, is a water bird of sub-Saharan Africa and Iraq.

The African darter is a member of the darter family, Anhingidae, and is closely related to American (Anhinga anhinga), Oriental (Anhinga melanogaster), and Australasian (Anhinga novaehollandiae) darters.

The African darter is 80 cm (31 in) long. Like other anhingas, it has a very long neck. The male is mainly glossy black with white streaking; females and immature birds are browner. The African darter differs in appearance from the American darter most recognisably by its thin white lateral neck stripe against a rufous background colour. The pointed bill prevents confusion with cormorants.

The African darter is found throughout sub-Saharan Africa wherever large bodies of water occur; overall the species remains widespread and common.

The only non-African subspecies, the Levant darter (Anhinga rufa chantrei), occurred at Lake Amik (Amik Gölü) in south-central Turkey, in the Hula Valley lake and marshes in northern Israel and in the Mesopotamian Marshes of the lower Euphrates and Tigris rivers in southern Iraq. The Turkish population disappeared during the 1930s and the Israeli population during the drainage of the Hula in the 1950s. In Khuzestan, 110 birds were counted in 1990, but the subspecies was feared extinct as a result of oil spills during the Gulf War and the drainage of the Mesopotamian Marshes that followed it. However, a small population was documented in the Hawizeh Marshes in 2007. The drainage of the marshes was interrupted and reversed after the Iraq War.

This species builds a stick nest in a tree and lays 3–6 eggs. It often nests with herons, egrets and cormorants.

It often swims with only the neck above water, hence the common name snakebird. This, too, is a habit shared with the other anhingas. It feeds on fish, which it catches by diving.

Unlike many other waterbirds the feathers of the African darter do not contain any oil and are therefore not waterproof. Because of this, the bird is less positively buoyant and its diving capabilities are enhanced. After diving for fish, the feathers can become waterlogged. In order to be able to fly and maintain heat insulation, it needs to dry its feathers. Thus the African darter is often seen sitting along the waterside spreading its wings and drying its feathers in the wind and the sun along with cormorants, which may share its habitat. 

27-12-2023 KOTU CREEK, GAMBIA - 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.

Pied kingfishers breed in all months near the equator. In the northern and southern parts of their range they breed during the late winter. Breeding occurs from August to November in South Africa. In Egypt breeding occurs from March to May.

27-12-2023 KOTU CREEK, GAMBIA - 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. 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.

 

27-12-2023 KOTU CREEK, GAMBIA - GIANT KINGFISHER (Megaceryle maxima ssp maxima)

The giant kingfisher (Megaceryle maxima) is the largest kingfisher in Africa, where it is a resident breeding bird over most of the continent south of the Sahara Desert, other than the arid southwest.

The first formal description of the giant kingfisher was by the German naturalist Peter Simon Pallas in 1769 under the binomial name Alcedo maxima. The current genus Megaceryle was erected by the German naturalist Johann Jakob Kaup in 1848.

There are two subspecies:

M. m. maxima (Pallas, 1769) – Senegal and Gambia to Ethiopia and south to South Africa

M. m. gigantea (Swainson, 1837) – Liberia to northern Angola and western Tanzania, island of Bioko

The nominate subspecies M. m. maxima occurs in wooded savanna while M. m. gigantea prefers tropical rainforest.

The giant kingfisher is 42–46 cm (16.5–18 in) long, with a large shaggy crest, a large black bill and fine white spots on black upperparts. The male has a chestnut breast band and otherwise white underparts with dark flank barring. The female has a white-spotted black breast band and a chestnut belly. The forest race M. m. gigantea is darker, less spotted above, and more barred below than the nominate race, but the two forms intergrade along the forest edge zone.

The call is a loud wak wak wak.

In South Africa breeding takes place between September and January, in Zimbabwe from August to March, in Zambia March to April and in Liberia December to January.[5]

The giant kingfisher is monogamous and a solitary breeder. The nest is a long horizontal tunnel that is excavated into a river bank by both sexes using their feet and bills. The entrance hole is 11 cm (4.3 in) high and 15 cm (5.9 in) wide. The tunnel is typically 2 m (6 ft 7 in) in length but a tunnel of 8.5 m (28 ft) has been recorded. A clutch of around three eggs is laid in a chamber at the end of the tunnel.

The Giant Kingfisher frequents rivers, streams, lakes, dams and even mountain streams with marginal wooded areas, both in forests and savannahs. It is also found in coastal lagoons, mangroves, estuaries and seashores, and occasionally on stagnant pools along dried-up rivers. It can be seen up to 100 metres from the water. In Tanzania, it may occur up to 1600 metres of elevation.

The race “maxima” is found from Senegambia to W Ethiopia and S Angola, N Botswana and South Africa, mainly is the East half, S to Cape Town and SW.

The race “gigantea” occurs in forest from Liberia to N Nigeria, E to W Tanzania and S to N Angola.

 

The Giant Kingfisher feeds mainly on aquatic preys such as fish, river crabs, amphibians and also small reptiles and insects.

 

30-12-2023 NGALA LODGE, GAMBIA - SPECKLED PIGEON (Columba guinea)

 Big, dark pigeon with white spots across the shoulder and a big red patch of bare skin around the eye. In flight, shows a gray tail band and rump. Found in many different open habitats, and nests in towns and cities and on cliffs. Only absent from thick forest. Common vocalizations are a “rrrour” call and an accelerating series of hoots. Somewhat similar to Rameron Pigeon, but largely absent from forest, and shows much larger wing spots and red rather than yellow bare facial skin.

30-12-2023 BAKAU, GAMBIA - CRIMSON SPECKLED FLUNKEY MOTH (Utetheisa pulchella)

Utetheisa pulchella, the crimson-speckled flunkey, crimson-speckled footman, or crimson-speckled moth, is a moth of the family Erebidae. The species was first described by Carl Linnaeus in his 1758 10th edition of Systema Naturae.

This common widespread species can be found in most of Europe (as a migrant), in the entire Afrotropical realm, North Africa, in the Near East and Central Asia, in the western Indomalayan realm (not known east of Myanmar.) In the United Kingdom it is only a sporadic migrant. These moths inhabit dry open places, meadows, shrublands, grasslands and parks.

The wingspan of Utetheisa pulchella can reach 29–42 mm. The front wings are narrow, white or cream coloured with a variable pattern of numerous small black spots located between the larger-sized bright red spots. Sometimes the red spots are merged to transversal bands. The hindwings are wide, white, with an irregular black border along the outer edge and two black markings in the middle of the cell. The head and thorax range from cream colour to buff yellow, with the same pattern as the wings. The antennae are long and monofiliform. The abdomen is smooth, with a white background.

Caterpillars are warty, dark brown or greyish, with tufts of greyish hairs, an orange crossline on each segment, a wide whitish line along the back and two other lateral white lines.

This species in southern Europe overwinters as a caterpillar. Pupation occurs on the ground near the host plants, usually on fallen leaves and dead vegetation, or pieces of bark and old wood. During mild winters in temperate and typically Mediterranean climates this species hibernates as pupae. Adults of this multivoltine species usually are present from March to early November in three generations a year, but in the tropics, they develop continuously. They fly both day and night and come to light. The polyphagous larvae feed on a range of herbaceous plants, mainly on forget-me-not (Myosotis), Echium, Borago officinalis, Solanum, Plantago lanceolata and Anchusa species. In the Afrotropical realm they mainly feed on Trichodesma zeylanicum, Lithospermum, Heliotropium, Trichodesma and Gossypium species.

Due to their food, the caterpillars accumulate a large amount of alkaloids, consequently also the moths are toxic and unpalatable to birds. The characteristic colouration of its wings serve as a sign of warning to their predators (aposematism).

31-12-2023 NGALA LODGE, GAMBIA - WHITE CROWNED ROBIN CHAT (Cossypha albicapillus)

A large and colorful robin-chat with a black face mask that continues onto the chin. The color of the crown is pure white in the far western part of the range, and white with black markings elsewhere. A shy bird of dense thickets, gardens, and forest, often along rivers and streams. Similar to Snowy-crowned Robin-Chat, but larger, usually with black markings in the white crown, and with a black rather than orange chin. Usually detected by song, a fast and complex mix of musical whistles.

The white-crowned robin-chat is a species of bird in the family Muscicapidae. It is found in Benin, Burkina Faso, Cameroon, Central African Republic, Ivory Coast, Ethiopia, Gambia, Ghana, Guinea, Guinea-Bissau, Mali, Niger, Nigeria, Senegal, Sierra Leone, South Sudan, and Togo. Its natural habitats are dry savanna and subtropical or tropical moist shrubland.

31-12-2023 ATLANTIC BLV, GAMBIA - VILLAGE WEAVER (Ploceus cucullatus)

The village weaver (Ploceus cucullatus), also known as the spotted-backed weaver or black-headed weaver (the latter leading to easy confusion with P. melanocephalus), is a species of bird in the family Ploceidae found in much of sub-Saharan Africa. It has also been introduced to Portugal and Venezuela as well as to the islands of Hispaniola, Martinique, Puerto Rico, Mauritius and Réunion.

This often abundant species occurs in a wide range of open or semiopen habitats, including woodlands and human habitation, and frequently forms large noisy colonies in towns, villages, and hotel grounds. This weaver builds a large coarsely woven nest made of grass and leaf strips with a downward-facing entrance, which is suspended from a branch in a tree. Two or three eggs are laid. Village weavers are colonial breeders, so many nests may hang from one tree.

Village weavers feed principally on seeds and grain, and can be a crop pest, but readily take insects, especially when feeding young, which partially redresses the damage to agriculture. The calls of this bird include harsh buzzes and chattering.

 

31-12-2023 ATLANTIC BLV, GAMBIA - BEAUTIFUL SUNBIRD (FEMALE) (Cinnyris pulchellus)

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. 

31-12-2023 ATLANTIC BLV, GAMBIA - WESTERN CATTLE EGRET (Bubulcus ibis ssp. ibis)

The western cattle egret (Bubulcus ibis) is a species of heron (family Ardeidae) found in the tropics, subtropics and warm temperate zones. Most taxonomic authorities lump this species and the eastern cattle egret together (called the cattle egret), but some (including the International Ornithologists' Union) separate them. Despite the similarities in plumage to the egrets of the genus Egretta, it is more closely related to the herons of Ardea. Originally native to parts of Asia, Africa and Europe, it has undergone a rapid expansion in its distribution and successfully colonised much of the rest of the world in the last century.

It is a white bird adorned with buff plumes in the breeding season. It nests in colonies, usually near bodies of water and often with other wading birds. The nest is a platform of sticks in trees or shrubs. Western cattle egrets exploit drier and open habitats more than other heron species. Their feeding habitats include seasonally inundated grasslands, pastures, farmlands, wetlands and rice paddies. They often accompany cattle or other large mammals, catching insect and small vertebrate prey disturbed by these animals. Some populations of the cattle egret are migratory and others show post-breeding dispersal. 

31-12-2023 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. 

31-12-2023 NGALA LODGE, GAMBIA - SENEGAL COUCAL (Centropus senegalensis)

The Senegal coucal (Centropus senegalensis ) is a member of the cuckoo order of birds, the Cuculiformes, which also includes the roadrunners, the anis, and the hoatzin. It is a medium-sized member of its genus and is found in lightly-wooded country and savannah in central and southern Africa.

This is a medium-sized species at 39 cm (15 in). Its crown, nape and upper parts, bill, legs and long tail are black, the eyes are red, the wings are chestnut, and the underparts are creamy white, with blackish barring on the flanks. The sexes are similar, but juveniles are browner and more heavily barred above, with buff to cinnamon, barred and streaked underparts.

It is a widespread species distributed through much of central and southern Africa south of the Sahara Desert. The range extends from Senegal in the west to Ethiopia and Kenya in the east, and Angola and Congo to the south. A separate population in southern Africa is centred on Zambia, Zimbabwe and northern Botswana. The Senegal coucal is a bird of grassy habitats with trees, such as bushes and savannah.

31-12-2023 BAKAU, GAMBIA - BROAD BILLED ROLLER (Eurystomus glaucurus)

The broad-billed roller (Eurystomus glaucurus) is a member of the roller family of birds which breeds across tropical Africa and Madagascar in all but the driest regions. It is a wet season breeder, which migrates from the northern and southern areas of its range towards the moister equatorial belt in the dry season.

The broad-billed roller is 29–30 cm in length. It has a warm back and head, lilac foreneck and breast, with the rest of the plumage mainly brown. The broad bill is bright yellow. Sexes are similar, but the juvenile is a drabber version of the adult, with a pale breast. The broad-billed roller is striking in its strong direct flight, with the brilliant blues of the wings and tail contrasting with the brown back.

The call of the broad-billed roller is a snarling k-k-k-k-k-r-r-r-r-r sound.

This is a species of open woodland with some tall trees, preferably near water. These rollers often perch prominently on trees, posts or overhead wires, like giant shrikes.

They are inactive for most of the day, apart from chasing intruders, but in late afternoon they hunt for the swarming ants and termites on which they feed, sometimes in groups of 100 or more rollers. They drink like swallows, dipping their bills into water in flight.

This bird nests in an unlined hole in a tree cavity, laying 2-3 eggs.

31-12-2023 BAKAU, GAMBIA - CITRUS SWALLOWTAIL BUTTERFLY

Papilio demodocus, the citrus swallowtail or Christmas butterfly, is a swallowtail butterfly which commonly occurs over the entirety of sub-Saharan Africa, including Madagascar, besides the southern Arabian Peninsula. The caterpillars feed on various native plants of especially the family Rutaceae, but have also taken to the leaves of cultivated citrus trees.

Citrus swallowtails pass through approximately three generations per year.

Eggs

Female butterflies lay their eggs singly on citrus leaves. After about six days, the egg hatches into an immature larva.

Immature larva

The immature larvae are black, yellow, and white with spikes. Their coloration provides effective camouflage, as they resemble bird droppings. They grow to a length of 10 or 15 mm before changing into mature larvae.

Mature larva

Mature larvae are green with white or pink markings and eyespots. They grow to a maximum length of about 45 mm.

Mature caterpillars lack the camouflage of their immature state. Instead, when threatened by a bird or other predator, they produce a forked, orange-coloured organ known as an osmeterium. The organ emits a strong smell which acts as a discouragement to the predator. The larvae are sometimes known as 'orange dogs'.

Pupa

The caterpillars attach themselves to branches with silk, transforming into pupae. They remain in the pupal form for two to three weeks before emerging as adults.

Adult

Adult butterflies have black and yellow markings with red and blue eyespots. Female butterflies tend to be larger than males.

 

As with most butterflies, various predators, parasitoids and diseases attack Papilio demodocus, so that integrated pest management is generally the most rational approach to control of infestations, paying due attention to avoiding destruction of the populations of enemies. In particular parasitic wasps in the family Encyrtidae, such as some species of the genus Ooencyrtus develop in Papilio eggs. Other parasitoidal wasps in families such as Chalcididae and Braconidae (for example genus Apanteles) attack the larvae, and Pteromalidae (for example genus Pteromalus) are parasitoids of the pupae. Predatory insects such as certain Heteroptera, in particular Reduviidae known as assassin bugs, and some Pentatomidae attack the larvae, and certain Mantodea such as genus Sphodromantis attack both larvae and adults.

28-12-2023 TENDABA, 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 is a large bird, nearly the size of a jackdaw at 28–30 cm (11–12 in). It has a very dark brown back, buffy or chalky white head, neck and breast, with the rest of the plumage mainly blue. Adults have 6 cm (2.4 in) tail streamers. Sexes are similar, but the juvenile is a drabber version of the adult.

The blue-bellied roller is striking in its strong direct flight, with the brilliant blues of the wings contrasting with the dark back and cream colored head, and the tail streamers trailing behind.

The call of blue-bellied roller is a harsh clicking ga-ga-ga sound.

This is a common bird of warm open country with some trees. These rollers often perch prominently on trees, posts, or overhead wires, like giant shrikes, whilst watching for the grasshoppers and other large insects on which they feed.

The display of this bird is a lapwing-like display, with the twists and turns that give this species its English name. It nests in a hole in a tree - a tree cavity. 

30-12-2023 BAKAU, GAMBIA - YELLOW BILLED KITE (Milvus migrans ssp. parasitus)

The yellow-billed kite (Milvus aegyptius) is the Afrotropic counterpart of the black kite (Milvus migrans), of which it is most often considered a subspecies. However, DNA studies suggest that the yellow-billed kite differs significantly from black kites in the Eurasian clade, and should be considered as a separate, allopatric species.

The yellow-billed kite was formally described in 1788 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He specified that the bird was found in Egypt, placed it with the eagles, falcons and relatives in the genus Falco and coined the binomial name Falco aegyptius. Unusually Gmelin did not cite a source for his information. The yellow-billed kite is now one of three kites placed in the genus Milvus that was introduced in 1799 by the French naturalist Bernard Germain de Lacépède.

There are two subspecies: M. a. parasitus (Daudin, 1800) , found throughout most of sub-Saharan Africa (including Madagascar), except for the Congo Basin (with intra-African migrations) and M. a. aegyptius (Gmelin, JF, 1788) of Egypt, south-west Arabia and the Horn of Africa (which disperses south during the non-breeding season).

The yellow-billed kite was formerly considered as conspecific with the black kite (Milvus migrans). A molecular phylogenetic study published in 2005 compared DNA sequences of two mitochondrial loci of the red, black and yellow-billed kites. It found that there was significant divergence between the three species, but unexpectedly, the two clades corresponding to the M. a. aegyptius and M. a. parasitus subspecies did not form a monophyletic group.

 As suggested by its name, the yellow-billed kite is easily recognized by its entirely yellow bill, unlike that of the black kite (which is present in Africa as a visitor during the North Hemisphere winter). However, immature yellow-billed kites resemble the black kites of the corresponding age.

They are found in almost all habitats, including parks in suburbia, but rare in the arid Namib and Karoo. They feed on a wide range of small vertebrates and insects, much of which is scavenged.
