18-4-2018 CHOBE NAT PARK, BOTSWANA - VERVET MONKEY (Chlorocebus pygerythrus)

The vervet is a small, black-faced monkey, common in East Africa. There are several subspecies of vervet monkeys, but, generally, the body is a greenish-olive or silvery-gray. The face, ears, hands, feet, and the tip of the tail are black, but a conspicuous white band on the forehead blends in with the short whiskers. The males are slightly larger than the females and easily recognized by a turquoise-blue scrotum and red penis. The vervet is classified as a medium- to a large-sized monkey. The tail is usually held up, with the tip curving downward, and the arms and legs are approximately equal lengths.

Vervet monkeys are sometimes viewed as pests.

Vervets living near areas inhabited by people can become pests, stealing food and other items and raiding crops. This leads to a heavy annual slaughter by poison, traps, and guns.

They have become valuable to research.

In recent years, vervet monkeys have been considered a valuable research animal, making live trapping prevalent as well.

The small monkey’s society is built on complex but stable social groups (called troops) of ten to 50 individuals — mainly adult females and their offspring. There is a strict social hierarchy among troop members. Males transfer troops at least once in their lifetime, beginning at puberty. This is a dangerous process, not only because of the predators they may encounter in transit but also because troops dislike immigrants.

The hierarchical system controls feeding, mating, fighting, friendships, survival, and even grooming — an important part of the vervet’s life. They spend several hours each day removing parasites, dirt, and other materials from one another’s fur. In the hierarchy, dominant individuals receive the most grooming.

Infants are cherished in vervet society.

Newborns have black hair and a pink face, and it takes three or four months before they acquire adult coloration. Infants spend the first week of life clinging to their mother's stomach. After about the third week, they begin to move about by themselves and attempt to play with other young monkeys. Infants are of great interest to the other monkeys in the troop; subadult females do everything possible to be allowed to groom or hold a new infant. Researchers report that usually a female's close family members will have the most unrestricted access to the babies. As the infants grow, they play not only with monkeys but also with other young animals.

Vervet monkeys enjoy a mostly vegetarian diet.

Leaves and young shoots are most important in their diet, but bark, flowers, fruit, bulbs, roots, and grass seeds are also consumed. Their mainly vegetarian diet is supplemented with insects, grubs, eggs, baby birds, and sometimes rodents and hares. Vervets rarely drink water.

In East Africa, vervet monkeys can live in mountain areas up to about 4,000 meters (13,000 feet), but they do not inhabit rainforests or deserts. Their preferred habitat is acacia woodland along streams, rivers, and lakes.

The vervet monkey, or simply vervet, is an Old World monkey of the family Cercopithecidae native to Africa. The term "vervet" is also used to refer to all the members of the genus Chlorocebus. The five distinct subspecies can be found mostly throughout Southern Africa, as well as some of the eastern countries. 

Scientific name: Chlorocebus pygerythrus

Conservation status: Least Concern (Population stable)

8-4-2018 CHOBE NAT PARK, BOTSWANA - PIONEER WHITE BUTTERFLY (belenois aurota)

Belenois aurota, the pioneer or pioneer white or caper white, is a small to medium-sized butterfly of the family Pieridae, that is, the yellows and whites, which is found in South Asia and Africa. In Africa, it is also known as the brown-veined white, and is well known during summer and autumn when large numbers migrate north-east over the interior.

The upperside of males is white with the forewing having the costa from base to base of vein 11 dusky black and then jet black continuing into a widened and curving short streak along the discocellulars to the lower apex of the cell; apical area diagonally with the termen black, the former with six elongate outwardly pointed spots of the ground colour enclosed one in each of the interspaces 3, 4, 5, 6, 8, and 9. Hindwing: uniform, the black along the venation on the underside seen through by transparency; termen between veins 2 and 6 somewhat broadly black, with a series of four round spots of the ground colour in the interspaces; below vein 2 and above vein 6 the termen is very narrowly black. Underside: forewing white, markings similar, more clearly defined, the white spots within the black apical area larger. Hindwing: yellowish white, all the veins very broadly bordered with black; interspaces 1, 2, 6, and 7 with crossbars of black, beyond which there is a subterminal, somewhat broad, transverse band of black between veins 2 and 6. Cilia of both forewings and hindwings white alternated with black.

The ground colour on both upper and undersides variable, often cream coloured above; beneath: in some specimens, the base of cell and the elongate spots in apical area of forewing, and the whole surface of the hindwing varies to rich chrome yellow.

Female similar; the black markings on both upper and undersides broader, the white spots on black apical area of forewing often sub-obsolete above.

Antennae in both sexes black, sparsely sprinkled with white dots; head, thorax and abdomen above and below white: thorax above often bluish grey.

18-4-2018 CHOBE NAT PARK, BOTSWANA - WATER THICK NEE (Barhinus Vermiculatus)

The Water Thick-knee, also known as the Water Dikkop (Burhinus vermiculatus), presents a striking figure with its 38 to 41 cm (15–16 in) stature and a weight range of 293–320 g (10.3–11.3 oz). This bird is characterized by a robust bill, black with a hint of yellow at the base, broad and blunt wings, and a rather short tail.

When identifying the Water Thick-knee, look for its heavy bill with a yellow base, which is quite distinctive. The wings are broad and blunt, which can be observed when the bird stretches them. The tail is short, which is noticeable when the bird is in flight or when it fans its tail feathers.

The Water Thick-knee is typically found along the edges of lakes, estuaries, and rivers. It also frequents mangroves and some sheltered beaches, often requiring nearby bushes or woodlands for shelter. Its habitat range extends from sea level up to 1,800 m (5,900 ft).

This species enjoys a widespread distribution across sub-Saharan Africa, with sightings reported in countries such as Angola, Botswana, Burkina Faso, and many others, all the way to South Africa.

The Water Thick-knee is a nocturnal terrestrial feeder, often venturing up to 1 km (0.62 mi) away from water to forage. It is known for its unique nesting behavior, often laying its eggs adjacent to or directly on top of Nile crocodile nests, engaging in a symbiotic mutualism with the crocodiles.

The Water Thick-knee is known to be vocal, especially when acting as a sentry for its nest or the crocodile nests it shares. Its calls are used to alert the crocodile of potential threats.

Breeding typically occurs in the dry season or early rainy season. The Water Thick-knee is monogamous, with both parents diligently guarding the nest and brooding the eggs. The nest is a simple scrape in the ground, and the clutch consists of two sandy-yellow eggs. Incubation lasts for 22-25 days, with both parents sharing the responsibility of feeding the young.

The Water Thick-knee can easily be confused with the Spotted Thich-knee.

The diet of the Water Thick-knee includes insects, crustaceans, and mollusks, which it forages for during the night.

The Water Thick-knee is currently listed as Least Concern on the IUCN Red List, indicating that it is not at immediate risk of population decline.

18-4-2018 CHOBE NAT PARK, BOTSWANA - CHACMA BABOON (Papio ursinus)

The Chacma baboon (Papio ursinus) is a member of the Old World monkey family. It is one of the largest of all monkeys. Located primarily in southern Africa, the chacma baboon has a wide variety of social behaviors, including a dominance hierarchy, collective foraging, adoption of young by females, and friendship pairings. In general, the species is not threatened, but hunting, trapping, and accidents kill or remove many baboons from the wild, thereby reducing their numbers and disrupting their social structure.

The Chacma baboon is perhaps the longest species of monkey and it is also one of the heaviest. Adult males can in some instances be about twice as long and three times as heavy as adult females. Perhaps the most distinctive feature of this baboon is its long, downward-sloping face. The Chacma baboon is generally dark brown to gray in color, with a patch of rough hair on the nape of its neck. Unlike the males of northern baboon species (Guinea, hamadryas, and Olive baboons), Chacma males do not have a mane. The three subspecies are differentiated by size and color. The Cape chacma is a large, heavy, dark-brown, and has black feet. The Gray-footed chacma is slightly smaller than the Cape chacma, lighter in color and build, and has gray feet. The Ruacana chacma generally appears to be a smaller, less darkly colored version of the Cape chacma.

Chacma baboons are found throughout southern Africa, ranging from South Africa north to Angola, Zambia, and Mozambique. They live in diverse habitats from woodlands to savannas, steppes, and sub-deserts. Chacma baboons are found in the Kalahari Desert as well as on the alpine slopes of the Drakensberg. They usually sleep on hills, cliffs, or large trees and during the day, avoid arid areas with a lack of water.

Chacma baboons are diurnal, spending most of the day on the ground. They are highly sociable animals, living in troops, which consist of 20-80 individuals. The troops include males as well as females with their young. Members of a troop are in close ties with each other, sleeping, feeding, and grooming together. During the day the groups split into smaller subgroups, consisting of 4-5 females with their young and a dominant male, who leads the group and defends it from other males. They are always on the alert, living in troops for protection and watching for predators. When threatened, the baboons give out loud barks. Then the males run to attack while the females and young hide in a safe place among the trees. Chacma baboons communicate by vocalizations, using about 30 different sounds such as grunting, barking, or screaming. They also use gestures such as shoulder shrugs, yawns, or lip-smacking.

Chacma baboons have polygynandrous (promiscuous) mating system. The dominant male of a subgroup competes with other males for mating rights, though females of baboons mate with a number of males during their lives. They breed at any time of the year. The gestation period lasts about six months, yielding a single baby. The newborn infant clings onto its mother’s breast, grabs onto her fur and later rides on her back. The baby is weaned at the age of 8-12 months. By this time, females keep on living within the troop while males usually join another troop. Males become reproductively mature at 5 years old whereas females are mature at 3 years old.

18-4-2018 CHOBE NAT PARK, BOTSWANA - IMPALA (Aepyceros melampus)

The impala (Aepyceros melampus) is a medium-sized antelope that is found in Africa. It was first described to European audiences by German zoologist Hinrich Lichtenstein in 1812. Active mainly during the day, the impala may be gregarious or territorial depending upon the climate and geography. The impala is known for two characteristic leaps that constitute an anti-predator strategy.

Impala is an elegant and magnificent species of antelope. The animal has slender body with the identifying "M"-like marking on the rear. This medium-sized antelope possesses thin, pointed horns with tips, lying far apart from each other. Males of this species are identified by the characteristic "S"-like horns. The elegant limbs of these animals have scent glands behind the ankles. The overall coloration of their fur is red-brown with paler sides. In addition, they have black and white colored areas on their body. Thus, the tail, belly, chin, lips, inside ears as well as the lines above the eyes are colored with white. Meanwhile, black bands cover their thighs, tail, forehead and ear tips.

Impalas are distributed throughout the northeastern part of South Africa, Angola, southern Rwanda, Uganda, and Kenya. Close proximity to a water source is an important life condition for these animals. Generally, they prefer woodland with little undergrowth as well as low to medium-height grassland.

Impalas have polygynous mating system, where each male mates with a number of females. The period of peak breeding activity is March-May. During this period, pregnant females live in isolation to give birth. The gestation period lasts from 194 to 200 days, yielding a single calf, which weighs about 5kgs (11 lbs). After a few days, the calf and the female rejoin the herd. Then, after a while, the calf joins a crèche of other young impalas. They are weaned at 4-5 months old. Male impalas reach reproductive maturity at 1 year of age, while females are ready to breed when they are between 1 and 2 years old. Becoming reproductively mature, they, however, do not rush to establish territories. They typically start mating only at 4 years old.

These antelopes are both diurnal and nocturnal. They are most active just after sunrise and before sunset, socializing and moving with their herd, whereas, during the nighttime hours, impalas usually lie down and ruminate. Female impalas and their offspring gather into herds, containing from 15 to 100 individuals. The home range of each herd covers a territory, varying from 80 to 180 hectares. During the wet season, females become highly territorial, defending home ranges of their herds. On the other hand, young males form bachelor, non-territorial herds of up to 30 individuals. During the dry season, male and female herds can often be seen mixed together. Home ranges of mature breeding males vary from season to season. Thus, during the breeding season, they usually have smaller home ranges, which they fiercely defend. Males use a wide variety of methods to defend their home range, including fighting, tail-raising, chasing, roaring, erect posture as well as forehead marking and forehead rubbing.

18-4-2018 CHOBE NAT PARK, BOTSWANA - GREAT EGRET (Ardea alba)

The great egret, known scientifically as Ardea alba, is a majestic bird with a stately bearing and an impressive wingspan. This large egret is adorned with all-white plumage and can stand up to a meter tall. It is a cosmopolitan species, found across temperate and tropical regions worldwide.

To identify the great egret, look for its yellow bill and contrasting black legs and feet, which may vary slightly during the breeding season. During this time, the bill may darken, and the lower legs may lighten. The great egret also sports ornamental feathers on its back when in breeding plumage. Both sexes appear identical, and juveniles resemble nonbreeding adults. The great egret can be distinguished from the intermediate egret by the gape of its bill, which extends well beyond the back of the eye.

The great egret favors habitats close to water, such as large lakes with reed beds and other extensive wetlands. It nests in colonies, often at heights of 10 to 40 feet within trees.

This bird has a vast range, occurring worldwide in suitable habitats. It is particularly common across the Sun Belt of the United States and throughout the Neotropics.

The great egret is known for its slow, graceful flight with its neck retracted, a characteristic of herons and bitterns. It walks with its neck extended and wings held close. Generally silent, it may emit a low, hoarse croak when disturbed and a louder croaking at breeding colonies.

18-4-2018 CHOBE NAT PARK, BOTSWANA - EGYPTIAN GOOSE (Alopochen aegyptiaca)

The Egyptian goose, Alopochen aegyptiaca, is a striking bird, native to Sub-Saharan Africa and the Nile Valley. It is a member of the Anatidae family, which includes ducks, geese, and swans. This species is unique in its appearance, resembling a goose more than a duck when in flight, with a heavy and robust stature. Adults typically measure between 63 to 73 centimeters in height.

Both sexes of the Egyptian goose display identical plumage, though males are generally larger. Plumage tones can vary from grey to brown, not necessarily indicative of age or sex. Mature birds boast a significant white patch on their wings, concealed by wing coverts when at rest but prominently displayed when the bird is agitated or in flight.

The Egyptian goose favors open or semi-open environments, often found near freshwater sources. Its habitat ranges from lowlands to high altitudes, such as the Ethiopian Highlands, up to 4,000 meters above sea level. It avoids dense forests and deserts.

This species is widespread and common in its native range, though numbers have dwindled in the northern Nile Valley. Historically found in southeastern Europe and parts of the Middle East, its presence in these areas has diminished.

The Egyptian goose is largely terrestrial, capable of perching on trees and buildings. It is known for its aggressive territorial behavior, especially during breeding season, and is not hesitant to engage in aerial combat with intruders. The species is monogamous, with both parents caring for their offspring.

20-4-2018 OKAVANGO DELTA, BOTSWANA - MARTIAL EAGLE (Polemaetus bellicosus)

The Martial Eagle (Polemaetus bellicosus), a formidable raptor, reigns over the sub-Saharan skies. This solitary species, the sole member of its genus, is distinguished by its impressive size and power. With feathered tarsi characteristic of the booted eagle subfamily, it is one of the largest of its kind. The Martial Eagle is an apex predator, soaring high to stoop upon a diverse array of prey, from mammals to reptiles.

Adult Martial Eagles exhibit a dark brown plumage on their upperparts, head, and upper chest, with occasional lighter feather edges. Their underparts are white, marked with sparse blackish-brown spots. In flight, their long broad wings and short tail give them a distinctive silhouette. Juveniles are paler with a greyish mottled appearance and take up to seven years to acquire their adult plumage.

The Martial Eagle favors wooded belts within open savanna landscapes, avoiding dense forests and arid deserts. It is often found perched in an upright position in large trees, surveying its territory.

This eagle's range spans across sub-Saharan Africa, with higher densities in southern and parts of east Africa. It is more sporadic in west Africa, with notable populations in protected areas such as South Africa's Kruger National Park.

Martial Eagles spend a significant portion of their day aloft, soaring at great heights. They are solitary outside of the breeding season and exhibit a preference for less disturbed areas, likely due to the abundance of prey and aversion to human activity.

The Martial Eagle is not a frequent vocalizer, but it does emit a low mellow whistle as a contact call and a louder, trilling call during territorial displays.

Breeding occurs at various times across their range, with nests built high in large trees. They lay usually one egg, with the female performing most of the incubation. Fledglings remain dependent on their parents for several months post-fledging.

The Black-chested Snake Eagle may be confused with the Martial Eagle but is significantly smaller with different coloring and flight patterns. Juvenile Martial Eagles may be mistaken for juvenile Crowned Eagles but differ in wing and tail proportions.

Martial Eagles are opportunistic predators, with a diet comprising mammals, birds, and reptiles. They are known for hunting from a high soar, using their keen eyesight to spot prey from several kilometers away.

The Martial Eagle is currently classified as Endangered by the IUCN, with populations declining due to factors such as persecution, habitat destruction, and collisions with power lines. Conservation efforts focus on education and the expansion of protected areas.

19-4-2018 OKAVANGO DELTA, BOTSWANA - AFRICAN LION (FEMALE) (Panthera leo)

The lion (Panthera leo) is a large cat of the genus Panthera, native to Africa and India. It has a muscular, broad-chested body; a short, rounded head; round ears; and a dark, hairy tuft at the tip of its tail. It is sexually dimorphic; adult male lions are larger than females and have a prominent mane. It is a social species, forming groups called prides. A lion's pride consists of a few adult males, related females, and cubs. Groups of female lions usually hunt together, preying mostly on medium-sized and large ungulates. The lion is an apex and keystone predator.

The lion inhabits grasslands, savannahs, and shrublands. It is usually more diurnal than other wild cats, but when persecuted, it adapts to being active at night and at twilight. During the Neolithic period, the lion ranged throughout Africa and Eurasia, from Southeast Europe to India, but it has been reduced to fragmented populations in sub-Saharan Africa and one population in western India. It has been listed as Vulnerable on the IUCN Red List since 1996 because populations in African countries have declined by about 43% since the early 1990s. Lion populations are untenable outside designated protected areas. Although the cause of the decline is not fully understood, habitat loss and conflicts with humans are the greatest causes for concern.

One of the most widely recognised animal symbols in human culture, the lion has been extensively depicted in sculptures and paintings, on national flags, and in literature and films. Lions have been kept in menageries since the time of the Roman Empire and have been a key species sought for exhibition in zoological gardens across the world since the late 18th century. Cultural depictions of lions have occurred worldwide, particularly has a symbol of power and royalty.

Among felids, the lion is second only to the tiger in size. The size and weight of adult lions vary across its range and habitats. 

African lions live in scattered populations across sub-Saharan Africa. The lion prefers grassy plains and savannahs, scrub bordering rivers, and open woodlands with bushes. It rarely enters closed forests. On Mount Elgon, the lion has been recorded up to an elevation of 3,600 m (11,800 ft) and close to the snow line on Mount Kenya. Savannahs with an annual rainfall of 300 to 1,500 mm (12 to 59 in) make up the majority of lion habitat in Africa, estimated at 3,390,821 km2 (1,309,203 sq mi) at most, but remnant populations are also present in tropical moist forests in West Africa and montane forests in East Africa. The Asiatic lion now survives only in and around Gir National Park in Gujarat, western India. Its habitat is a mixture of dry savannah forest and very dry, deciduous scrub forest.

The lion is a generalist hypercarnivore and is considered to be both an apex and keystone predator due to its wide prey spectrum. Its prey consists mainly of medium-sized to large ungulates, particularly blue wildebeest, plains zebra, African buffalo, gemsbok and giraffe. It also frequently takes common warthog despite it being much smaller. In India, chital and sambar deer are the most common wild prey, while livestock contributes significantly to lion kills outside protected areas. It usually avoids fully grown adult elephants, rhinoceros and hippopotamus and small prey like dik-dik, hyraxes, hares and monkeys. Unusual prey include porcupines and small reptiles. Lions kill other predators but seldom consume them.

19-4-2018 OKAVANGO DELTA, BOTSWANA - SOUTHERN RED BILLED HORNBILL (Tockus rufirostris)

The Southern red-billed hornbill, Tockus rufirostris, is a distinguished member of the Bucerotidae family, gracing the savannas and drier bushlands of southern Africa with its presence. This bird is characterized by its striking red bill and the streaks of blackish plumage that extend from its ear coverts down the side of its neck.

Upon observing this species, one will note the sexual dimorphism where males are generally larger with slightly longer bills. The male's lower mandible may exhibit varying degrees of black pigmentation. Both sexes boast a yellow iris surrounded by pale orbital skin, ranging from pink to greyish hues. The throat is a pristine white, and the wing coverts are adorned with conspicuous spots.

The Southern red-billed hornbill is a native inhabitant of the savannas and dryer bushlands, thriving in these open environments where it can forage and nest.

This hornbill's range extends from Malawi and Zambia to southern Angola, northeastern Namibia, Botswana, Zimbabwe, eastern Eswatini, and northern South Africa, including Transvaal and northern KZN province. It is also found in the upper Zambezi valley of Mozambique, though it is mostly absent from the eastern lowlands.

A notable behavior of the Southern red-billed hornbill is its unique call, an accelerating series of notes that culminates in a crescendo of double notes. Unlike its congeners, this species does not engage in wing-raising displays.

The vocal repertoire of this hornbill includes a distinctive call that starts with a series of "kuk kuk kuk" notes and ends with a flourish of double notes, "kuk-we kuk-we."

The Southern red-billed hornbill can be confused with other red-billed hornbills, but it can be distinguished by its unique combination of yellow iris, pale orbital skin, and the pattern of blackish streaking on the neck.

The conservation status of the Southern red-billed hornbill is not explicitly mentioned, but given its wide distribution, it may not currently be of significant conservation concern. However, like all wildlife, it would benefit from ongoing habitat protection and monitoring.

19-4-2018 OKAVANGO DELTA, BOTSWANA - LILAC BREASTED ROLLER (Coracias caudatus)

The lilac-breasted roller (Coracias caudatus) is a member of the roller family, Coraciidae, resplendent in a panoply of pastel hues. This African bird is a sight to behold, with its lilac throat and breast, olive crown to mantle, and cheeks of lilac-rufous. The species is further adorned with long, black tail streamers, which juveniles lack. Unofficially, it is considered the national bird of Kenya.

In the field, the lilac-breasted roller is almost unmistakable. Adults boast a lilac throat that deepens into a darker lilac breast, with an olive crown and mantle. The cheeks and ear coverts are a lilac-rufous. Juveniles and immatures can be identified by their lack of tail streamers and a throat and breast of rufous-tawny with broad diffuse buffy-white streaks. The species is not sexually dimorphic, though males may be slightly larger.

The lilac-breasted roller favors open woodland and savanna, typically avoiding treeless expanses. They are often seen perched high, surveying the landscape for prey.

This species is widely distributed across Southern and Eastern Africa and is a vagrant to the southern Arabian Peninsula. It is most abundant in Kenya and can be found from sea level to elevations of 2,000 meters or more.

19-4-2018 OKAVANGO DELTA, BOTSWANA - DARTER (Anhinga rufa ssp. rufa)

The African darter, Anhinga rufa, is a striking waterbird known for its sinuous neck, which has earned it the nickname "snakebird." This species measures approximately 80 cm in length, with males displaying a glossy black plumage adorned with white streaking. Females and immature birds present a more subdued brown coloration.

Distinguishable from its relatives by a slender white stripe running down its neck set against a rufous backdrop, the African darter's pointed bill sets it apart from cormorants. Males are predominantly black with white streaks, while females and juveniles are browner.

The African darter frequents large bodies of water across sub-Saharan Africa, favoring environments where it can perch and dive with ease.

This bird is widespread and common throughout sub-Saharan Africa. A non-African subspecies, the Levant darter, was historically found in Turkey, Israel, and southern Iraq, but populations have faced significant declines due to habitat destruction and other environmental pressures.

20-4-2018 OKAVANGO DELTA, BOTSWANA - OKAVANGO MUD TURTLE (Pelusios bechuanicus)

The Okavango mud turtle or Okavango terrapin (Pelusios bechuanicus) is a species of turtle in the family Pelomedusidae endemic to Africa. It is found in Angola, Botswana, the Democratic Republic of the Congo, Namibia (Caprivi), Zambia, and Zimbabwe.

Found in central Africa, central Angola, northeastern Namibia, northern Botswana, Zimbabwe, and Zambia

The Okavango mud turtle is the largest species of the genus Pelusios. The carapace is oval and elongated, with a pronounced dome, and is evenly rounded at the edges which allows the turtle to appear as a smooth rock. The carapace is very dark, often almost black, and lightens up to yellow or orange only at the sides. The plastron is well developed and can close the shell completely, with a rounded front lobe that comes together to form the hinge that is characteristic of the genus.

The turtle is observed most often in clear, deep, calm waters, in rivers, and in vegetation-choked swamps. It is a semi-aquatic animal that remains in the water most of the year. It is observed outside of the water habitat only when seeking temporary aquatic refuge during the dry season. The breeding season occurs during the southern summer and nests are quite large, between 20 and 50 eggs. The turtle is most frequent prey to the shoe-billed stork and it is characteristically a carnivore, feeding on fish and invertebrates.

20-4-2018 OKAVANGO DELTA, BOTSWANA - ACANTHUS (Ruspolia hypocrateriformis)

Ruspolia hypocrateriformis is a species of plants with 24 observations.

Acanthus is a genus of about 30 species of flowering plants in the family Acanthaceae, native to tropical and warm temperate regions, with the highest species diversity in the Mediterranean Basin and Asia. This flowering plant is nectar-producing and depends on butterflies, such as Anartia fatima, and other nectar-feeding organisms to distribute its pollen. Common names include Acanthus and bear's breeches. The generic name derives from the Greek term ἄκανθος (akanthos) for Acanthus mollis, a plant that was commonly imitated in Corinthian capitals.

The genus comprises herbaceous perennial plants, rarely subshrubs, with spiny leaves and flower spikes bearing white or purplish flowers. Size varies from 0.4 to 2 m (1.3 to 6.6 ft) in height.

27-5-2018 MONTE CORONA, VALENCIA - TRUE WEEVIL (Stephanocleonus excoriatus)

The Curculionidae are a family of weevils, commonly called snout beetles or true weevils. They are one of the largest animal families with 6,800 genera and 83,000 species described worldwide. They are the sister group to the family Brentidae.

They include the bark beetles as the subfamily Scolytinae, which are modified  in shape in accordance with their wood-boring lifestyle. They do not much resemble other weevils, so they were traditionally considered a distinct family, Scolytidae. The family also includes the ambrosia beetles, of which the present-day subfamily Platypodinae was formerly considered the distinct family Platypodidae.

Adult Curculionidae can be recognised by the well-developed, downwards-curved snout (rostrum) possessed by many species, though the rostrum is sometimes short (e.g. Entiminae). They have elbowed antennae that end in clubs, and the first antennal segment often fits into a groove in the side of the rostrum. The body tends to be robust, convex, heavily sclerotised and covered in scales or bristles. Curculionidae range in size from 1–35 mm long, usually being 5–15 mm long. Most Curculionidae are sexually dimorphic with females (compared to males) having antennae positioned more basally and a longer, thinner rostrum.

Larval Curculionidae are C-shaped and lightly sclerotised, with minute antennae, robust mandibles and no legs.

Most weevils feed on plants as larvae and adults, and they include important pests of cultivated plants that chew holes in fruits, nuts and other parts. The long rostrum possessed by most adult weevils is used by females to help lay eggs (oviposit) inside plant tissue. Some feed on rotten wood or bark (e.g. Cossoninae and Cryptorhynchinae), and some are wood-borers that feed on ambrosia fungi (Platypodinae and some Scolytinae).

Although pesticide resistance hasn't historically been an issue with these insects, recently a mutation was discovered in association with the voltage-gated sodium channel in the species Sitophilus zeamais, indicating there is a lot to learn about how these insects adapt to changing environments.

20-4-2018 OKAVANGO DELTA, BOTSWANA - SOUTHERN AFRICAN GIRAFFE (Giraffa giraffa ssp. giraffa)

The South African giraffe or Cape giraffe (Giraffa giraffa or Giraffa camelopardalis giraffa) is a species or subspecies of giraffe found in South Africa, Namibia, Botswana, Zimbabwe, Eswatini and Mozambique. It has rounded or blotched spots, some with star-like extensions on a light tan background, running down to the hooves.

In 2016, the population was estimated at 31,500 individuals in the wild.

The IUCN currently recognizes only one species of giraffe with nine subspecies. The Cape giraffe, along with the whole species, were first known by the binomen Camelopardalis giraffa as described by German naturalist Johann Christian Daniel von Schreber in his publication Die Säugethiere in Abbildungen nach der Natur mit Beschreibungen (The Mammals Illustrated from Nature with Descriptions) during his travel in the Cape of Good Hope in 1784. Dutch naturalist Pieter Boddaert also described it under the binomial name Giraffa giraffa whilst also identifying the nominate specimen of said species under the ternary name Giraffa camelopardalis giraffa in 1785.

The South African giraffe has dark, somewhat rounded patches "with some fine projections" on a tawny background colour. The spots extend down the legs and get smaller. The median lump of males is less developed.

The South African giraffe is found in northern South Africa, southern Botswana, southern Zimbabwe, and south-western Mozambique. After local extinctions in various places, South African giraffes have been reintroduced in many parts of Southern Africa, including in Eswatini. They are common in both in and outside of protected areas. South African giraffes usually live in savannahs and woodlands where food plants are available. Giraffes are herbivorous. They feed on leaves, flowers, fruits and shoots of woody plants such as Acacia.

South African giraffes live in a fission–fusion society system based on factors such as sex, age, season, and kinship. This allows them to adapt to environmental changes.

At present[when?], the South African giraffe population is estimated at 37,000 individuals, showing an increase of over 150% over the past three decades. The International Union for the Conservation of Nature, the body that administers the world's official endangered species list, announced in 2016 that it was moving the giraffe from a species of Least Concern to Vulnerable status in its Red List of Threatened Species report. That means the animal faces extinction in the wild in the medium-term future if nothing is done to minimize the threats to its life or habitat.

South African giraffes are uncommon in captivity. As of 2010, there are around 45 South African giraffes breeding in zoos. Approximately 12,000 privately owned farms, ranches, and national parks maintain populations of this giraffe.

20-4-2018 OKAVANGO DELTA, BOTSWANA - TSESSEBE (Damaliscus lunatus)

The common tsessebe or sassaby (Damaliscus lunatus lunatus) is the southern, nominate subspecies of Damaliscus lunatus, although some authorities have recognised it as an independent species. It is most closely related to the Bangweulu tsessebe, sometimes also seen as a separate species, less to the topi, korrigum, coastal topi and tiang subspecies of D. lunatus, and less to the bontebok in the same genus. Common tsessebe are found in Angola, Zambia, Namibia, Botswana, Zimbabwe, Eswatini (formerly Swaziland), and South Africa.

Common tsessebe are among the fastest antelopes in Africa and can run at speeds up to 90 km/h.

Adult tsessebe are 150 to 230 cm in length They are quite large animals, with males weighing 137 kg and females weighing 120 kg, on average. Their horns range from 37 cm for females to 40 cm for males. For males, horn size plays an important role in territory defense and mate attraction, although horn size is not positively correlated with territorial factors of mate selection. Their bodies are chestnut brown. The fronts of their faces and their tail tufts are black; the forelimbs and thigh are greyish or bluish-black. Their hindlimbs are brownish-yellow to yellow and their bellies are white. In the wild, tsessebe usually live a maximum of 15 years, but in some areas, their average lifespan is drastically decreased due to overhunting and the destruction of habitat.

The most significant difference between the tsessebe, the southernmost subspecies, and the other topi subspecies is the incline of the horns, with the tsessebe having horns which are placed further apart from each other as one moves distally. This has the effect of the space between them having a more lunate profile when seen from a certain angle, as opposed to lyrate, more like that of a hartebeest. Tsessebe populations show variation as one moves from South Africa to Botswana, with southerly populations having on average the lightest pelage colour, smallest size and the least robust horns. Common tsessebe do not differ significantly from the Bangweulu tsessebe, the northernmost population, but in general the populations from that part of Zambia are on average the darkest-coloured and have the most robust horns, although differences are slight and individuals in both populations show variation in these characteristics which almost completely overlap each other.

Tsessebe are social animals. Females form herds composed of six to 10, with their young. After males turn one year of age, they are ejected from the herd and form bachelor herds that can be as large as 30 young bulls. Territorial adult bulls form herds the same size as young bulls, although the formation of adult bull herds is mainly seen in the formation of a lek. Tsessebe declare their territory through a variety of behaviors. Territorial behavior includes moving in an erect posture, high-stepping, defecating in a crouch stance, ground-horning, mud packing, shoulder-wiping, and grunting.

20-4-2018 OKAVANGO DELTA, BOTSWANA - AFRICAN LION (FEMALE) (Panthera leo)

The lion (Panthera leo) is a large cat of the genus Panthera, native to Africa and India. It has a muscular, broad-chested body; a short, rounded head; round ears; and a dark, hairy tuft at the tip of its tail. It is sexually dimorphic; adult male lions are larger than females and have a prominent mane. It is a social species, forming groups called prides. A lion's pride consists of a few adult males, related females, and cubs. Groups of female lions usually hunt together, preying mostly on medium-sized and large ungulates. The lion is an apex and keystone predator.

The lion inhabits grasslands, savannahs, and shrublands. It is usually more diurnal than other wild cats, but when persecuted, it adapts to being active at night and at twilight. During the Neolithic period, the lion ranged throughout Africa and Eurasia, from Southeast Europe to India, but it has been reduced to fragmented populations in sub-Saharan Africa and one population in western India. It has been listed as Vulnerable on the IUCN Red List since 1996 because populations in African countries have declined by about 43% since the early 1990s. Lion populations are untenable outside designated protected areas. Although the cause of the decline is not fully understood, habitat loss and conflicts with humans are the greatest causes for concern.

One of the most widely recognised animal symbols in human culture, the lion has been extensively depicted in sculptures and paintings, on national flags, and in literature and films. Lions have been kept in menageries since the time of the Roman Empire and have been a key species sought for exhibition in zoological gardens across the world since the late 18th century. Cultural depictions of lions have occurred worldwide, particularly has a symbol of power and royalty.

Among felids, the lion is second only to the tiger in size. The size and weight of adult lions vary across its range and habitats. 

25-3-2018 TABLE MOUNTAIN AVIARY, CAPE TOWN - BLACK AND WHITE CASQUED HORNBILL (Bycanistes subcylindricus)

The black-and-white-casqued hornbill is found in wooded habitats in central and western Africa, ranging from western Kenya to Côte d'Ivoire with an isolated population in north Angola. The black-and-white-casqued hornbill is found mostly in Ivory-Coast, with smaller populations in its surrounding countries for West-African populations. The Central-African populations are mostly in Uganda and Kenya as well as Cameroon with smaller populations in Gabon, Tanzania and Central Africa. They are tropical birds that live in regions with high amounts of forests and is rarely seen in on flat lands, especially due to its arboreal nature.

The black-and-white-casqued hornbill (Bycanistes subcylindricus) also known as the grey-cheeked hornbill, is a large black and white hornbill. It has an oversized blackish bill with a large casque on top. The female is slightly smaller than the male and has a significantly smaller casque. It is a monogamous species, and pairs nest in suitable tree cavities. The female usually lays up to two eggs. The diet consists mainly of figs, fruits, insects and small animals found in the trees.

Widespread and still locally common, the black-and-white-casqued hornbill is assessed as least concern on the IUCN Red List of Threatened Species.
