23-3-2018 BOULDERS BAY, CAPE TOWN - SOUTHERN BLACKLEG ORBWEAVER SPIDER (Trichonephila fenestrata ssp. fenestrata)


Trichonephilia fenestrata is a species of nephilid spider known from Africa. It was first described by Tamerlan Thorell in 1859 as Nephila fenestrata, and was later moved to Trichonephila when it was elevated to genus status by Kuntner in 2019.

Three subspecies are known from different parts of Africa. Males of this species often autotomize their legs as a counter-adaptation to the sexual cannibalism of females.

kingdom Animalia - animals »  phylum Arthropoda - arthropods »  class Arachnida - arachnids »  order Araneae - spiders »  family Araneidae - Orb-weaver spider »  genus Trichonephila »  species Trichonephila fenestrate


Orb-weaver spiders or araneids are members of the spider family Araneidae. They are the most common group of builders of spiral wheel-shaped webs often found in gardens, fields and forests. "Orb" can in English mean "circular", hence the English name of the group. Araneids have eight similar eyes, hairy or spiny legs, and no stridulating organs.

The family is cosmopolitan, including many well-known large or brightly colored garden spiders. With 3122 species in 172 genera worldwide, Araneidae is the third-largest family of spiders (behind Salticidae and Linyphiidae). Araneid webs are constructed in a stereotyped fashion. A framework of nonsticky silk is built up before the spider adds a final spiral of silk covered in sticky droplets.

23-3-2018 BOULDERS BAY, SOUTH AFRICA - CAPE WAGTAIL (Motacilla capensis ssp capensis)


The Cape wagtail, or Wells's wagtail, is a modestly adorned bird with a relatively short tail. Its upperparts are an unassuming olive grey, while the face is similarly hued, accented by a tan supercilium and dark lores. The underparts are a soft creamy white, occasionally showing a subtle pinkish tinge on the lower breast and belly. A dusky breast band is present, and the flanks share the olive-grey of the breast. The wings are a brownish black with pale feather edging, and the tail is predominantly blackish, save for the white outer feathers. Juveniles resemble adults but are a touch browner above and have a more yellowish hue below.

Look for the iconic black triangle on the chest, a key feature for identification. There is no sexual dimorphism in plumage, so males and females appear alike.

The Cape wagtail is a versatile species, inhabiting areas near water such as riverbanks, as well as rocky coastlines, farms, villages, cultivated lands, parks, gardens, and urban centres. In East Africa, it is typically found at altitudes above 2,000 meters.

22-4-2018 OKAVANGO DELTA, BOTSWANA - SMITH'S BUSH SQUIRREL (Paraderus Cepapi)


Smith's bush squirrel (Paraxerus cepapi), also known as the yellow-footed squirrel or tree squirrel, is an African bush squirrel which is native to woodlands of the southern Afrotropics.

It is found in Angola, Botswana, the DRCongo, Malawi, Mozambique, Namibia, South Africa, Tanzania, Zambia, and Zimbabwe. It is a common rodent which is diurnal by nature.

Its total length is 350 mm, half of which is tail. This species only weighs 200 g. The coat colour varies throughout the region. In the western and arid parts of its range, it is pale grey, and in the eastern localities, more brown. Its head and legs are a rusty colour. Colouration on the chest varies from yellowish to buff in the east, to white in the west. This squirrel's belly is white. These alert and ever busy creatures carry their long tails extended backwards.

Smith's bush squirrels are primarily vegetarian, but like most rodents, they take insect prey and use their front feet to manipulate food items when feeding. They scatter-hoard seeds next to tree trunks or grass tufts, thereby facilitating tree regeneration.


Essentially arboreal animals, they also spend a great deal of time on the ground, foraging for food. When disturbed, Smith's bush squirrels always seek the refuge of trees. At night, territorial family groups nest together in holes in trees. Offspring become sexually mature between six and nine months old, when they are forcibly evicted by the breeding pair. The males are mainly responsible for territorial defense, although females also chase intruders when they care for dependent pups. To promote group cohesion, a common scent is shared by mutual grooming, which is an important facet of the social fibre of this species. Smith's bush squirrels are diligent in their grooming and a mother tree squirrel holds her offspring down with her fore legs while grooming it with licks, nibbles, and scratches with her claws.

A conspicuous feature of their behaviour when under threat is 'mobbing': all the members of the colony make harsh clicking sounds while they flick their tails, building up momentum and gradually getting louder. In some areas, they are solitary, or are found in small family groups; a lone tree squirrel relies on its wits when in danger and always keeps a branch or the trunk of a tree between it and the enemy. Smith's bush squirrels are always alert, and when alarmed, run away with great speed, making for the nearest tree where they lie motionless, flattened against a branch.

22-4-2018 OKAVANGO DELTA, BOTSWANA - RING NECKED DOVE (Streptopelia capicola)


The Ring-necked Dove, also known as the Cape Turtle Dove or Half-collared Dove, graces the skies of East and southern Africa with its presence. This bird, mostly sedentary in nature, boasts a semi-collar of black feathers on its lower nape, a characteristic it shares with its Streptopelia kin. The upper parts of its body are cloaked in the darkest shades of grey and brown, while the lower belly and vent gleam white. Notably, the tail feathers are edged with white, a detail most visible during their display flight.

Adult Ring-necked Doves exhibit a variety of grey and brown tones with a hint of lavender on the nape, and a paler underside with a touch of pinkish lavender. The white lower belly and crissum starkly contrast with the slate grey tail feathers tipped with white. Males and females are similar in appearance, though males are marginally larger, measuring between 25–26.5 cm in length and weighing 92–188 g. Their eyes are a deep, almost black hue, complemented by a black bill and dark purple feet. Juveniles are duller and lack the semi-collar, with buff edges on their upper parts and greyish-white edges below.

The Ring-necked Dove thrives in a variety of open habitats, from semi-desert scrub and savannahs to woodlands and farmlands. It avoids closed forests and the arid dune fields and gravel plains of the Namib. In southern Africa, they are frequently spotted in fynbos regions and various grassland types, often near trees planted in groves around farmsteads.

22-4-2018 OKAVANGO DELTA, BOTSWANA - RED BILLED SPURFOWL (Pternistis adspersus)


The Red-billed Spurfowl, or Pternistis adspersus, presents a striking figure with its barred underparts and a distinctive yellow eye-ring. This bird, also known as the Red-billed Francolin, is a member of the Phasianidae family. Exhibiting sexual dimorphism, the males are notably larger, reaching lengths of 38 cm and weights between 340-635 grams, while the females are slightly smaller at 33 cm in length and weighing 340-549 grams.


When observing the Red-billed Spurfowl, look for the characteristic barred pattern on the underparts, which sets it apart from similar species such as the Natal Spurfowl. The yellow eye-ring is a conspicuous feature to aid identification. Males are larger than females, which can be a helpful distinction in the field.

The Red-billed Spurfowl is native to Southern Africa, where it frequents a variety of habitats.


This species is widely distributed across Southern Africa, with its range encompassing Angola, Botswana, Namibia, South Africa, Zambia, and Zimbabwe.

The Red-billed Spurfowl is known for its terrestrial habits, often seen foraging on the ground.

The Natal Spurfowl is similar in appearance but can be distinguished by the lack of barred underparts which are present in the Red-billed Spurfowl.

The IUCN Red List has classified the Red-billed Spurfowl as Least Concern, indicating that the species does not currently face a significant risk of extinction.

22-4-2018 OKAVANGO DELTA, BOTSWANA - MOURNING DOVE (Zenaida macroura)


The Mourning Dove, Zenaida macroura, is a member of the dove family, Columbidae. It is a medium-sized, slender bird with a soft, grayish-brown plumage and a long, pointed tail. It is known for its gentle appearance and mournful cooing, which has given rise to its name.

Adult Mourning Doves have light gray and brown feathers with a slightly pinkish hue on the underside. Males and females are similar, but males may exhibit more vibrant purple-pink patches on the neck. The eyes are surrounded by light blue skin, and a distinctive crescent of dark feathers lies below the eye. The tail is long and tapered, with the outer feathers being white, providing a stark contrast to the black inner feathers.

Mourning Doves are found in a variety of open and semi-open habitats, including urban environments, farms, prairies, grasslands, and areas with sparse woodland. They tend to avoid dense forests and swamps.


This species is widespread across North America, from southern Canada through the United States, Mexico, and into Central America. It is also found in the Greater Antilles and Bermuda.
Mourning Doves are known for their swift and direct flight, capable of reaching speeds up to 55 mph. They are strong fliers and exhibit a unique whistling sound from their wings during take-off and landing. These birds are also known for their sunbathing and rain bathing behaviors, often lying on the ground with one wing stretched out.

The male Mourning Dove's call is a sorrowful cooOOoo-wooo-woo-woooo, which is used to attract a mate. Other vocalizations include a soft ork when greeting and a short roo-oo as an alarm call. The wing whistle during flight is a distinctive characteristic of this species.

Mourning Doves are generally monogamous and may raise multiple broods in a single year, especially in warmer regions. Both parents share in the incubation duties and care for the young, known as squabs. The nests are often built with twigs and are relatively flimsy in construction.

The Mourning Dove may be confused with other dove species, but its long, pointed tail and distinctive wing whistle during flight are key identification features.

The diet of Mourning Doves consists almost exclusively of seeds. They forage on the ground and have been observed eating a wide variety of plant seeds, showing preferences for certain species.

4-5-2018 ULAL DE BOLDOVI, VALENCIA - SMALL WHITE BUTTERFLY (Pieris rapae)


Pieris rapae is a small- to medium-sized butterfly species of the whites-and-yellows family Pieridae. It is known in Europe as the small white, in North America as the cabbage white or cabbage butterfly, on several continents as the small cabbage white, and in New Zealand as the white butterfly. The butterfly is recognizable by its white color with small black dots on its wings, and it can be distinguished from P. brassicae by its larger size and the black band at the tip of its forewings.

The caterpillar of this species, often referred to as the "imported cabbageworm", is a pest to crucifer crops such as cabbage, kale, bok choy and broccoli. Pieris rapae is widespread in Europe and Asia; it is believed to have originated in the Eastern Mediterranean region of Europe, and to have spread across Eurasia thanks to the diversification of brassicaceous crops and the development of human trade routes. Over the past two centuries, it spread to North Africa, North America, New Zealand, and Australia, as a result of accidental introductions.


In appearance it looks like a smaller version of the large white (Pieris brassicae). The upperside is creamy white with black tips on the forewings. Females also have two black spots in the center of the forewings. Its underwings are yellowish with black speckles. It is sometimes mistaken for a moth due to its plain appearance. The wingspan of adults is roughly 32–47 mm (1.3–1.9 in).

Pieris rapae has a wingbeat frequency averaging 12.8 flaps per second.

The species has a natural range across Europe, Asia, and North Africa. It was accidentally introduced to Quebec, Canada, around 1860 and spread rapidly throughout North America. The species has spread to all North American life zones from Lower Austral/Lower Sonoran to Canada. Estimates show that a single female of this species might be the progenitor in a few generations of millions. It is absent or scarce in desert and semidesert regions (except for irrigated areas). It is not found north of Canadian life zone, nor on Channel Islands off the coast of southern California. By 1898, the small white had spread to Hawaii; by 1929, it had reached New Zealand and the area around Melbourne, Australia, and found its way to Perth as early as 1943. It does not seem to have made it to South America.


In Britain, it has two flight periods, April–May and July–August, but is continuously brooded in North America, being one of the first butterflies to emerge from the chrysalis in the spring and flying until hard freeze in the fall.

The species can be found in any open area with diverse plant association. It can be seen usually in towns, but also in natural habitats, mostly in valley bottoms. Although an affinity towards open areas is shown, the small white is found to have entered even small forest clearings in recent years.

The nominate subspecies P. r. rapae is found in Europe, while Asian populations are placed in the subspecies P. r. crucivora. Other subspecies include atomaria, eumorpha, leucosoma, mauretanica, napi, novangliae, and orientalis.

4-5-2018 EL PERELLO, VALENCIA - GREY HERON (Ardea cinerea)


The Grey Heron (Ardea cinerea) is a statuesque wading bird belonging to the family Ardeidae. It is a familiar sight in both rural and urban settings, often seen standing stoically along the water's edge. An adult Grey Heron is a large bird, reaching up to 100 cm in height, with a wingspan between 155 to 195 cm. It weighs between 1 to 2 kg. The plumage is predominantly ashy-grey above, with a greyish-white underbelly and some black on the flanks. A striking feature is the white head and neck adorned with a broad black stripe that extends from the eye to the black crest. The beak is pinkish-yellow, long, and sharply pointed, while the legs are a brown hue.

When identifying the Grey Heron, look for the white head with the black supercilium and crest, the long grey neck, and the ashy-grey wings and back. The underparts are lighter, and the legs are long and brown. Juveniles can be distinguished by their duller grey neck and smaller crest. The beak is a useful indicator of age, being brighter in breeding adults.
Grey Herons are highly adaptable and can be found in a variety of watery habitats including lakes, rivers, ponds, marshes, and coastal environments. They require shallow waters for foraging or areas with shelving margins where they can wade.


Native to temperate Europe and Asia, as well as parts of Africa, the Grey Heron has a broad range. Northern populations may migrate southwards in autumn, while others remain resident year-round. Vagrant sightings have occurred in the Caribbean, Bermuda, and parts of North America.

The Grey Heron exhibits a slow, deliberate flight with its neck retracted in an S-shape. It is known for its solitary foraging habits, often standing motionless or stalking prey through shallow waters. It is also a communal rooster, often found in trees or cliffs at night.

The primary call of the Grey Heron is a loud croaking "fraaank." At breeding colonies, a variety of guttural and raucous noises can be heard, including greeting calls between mates and alarm calls when predators are nearby.

Breeding takes place in colonies, or heronries, typically in high trees near water. Nests are reused and added to each year. The breeding season sees a clutch of three to five bluish-green eggs laid, which both parents incubate. Chicks fledge at 7-8 weeks old.

4-5-2018 ULAL DE BOLDOVI, VALENCIA - CLOUDED YELLOW BUTTERFLY (Colias croceus)


Colias croceus, clouded yellow, is a small butterfly of the family Pieridae, the yellows and whites.

Colias croceus has a wingspan of 46–54 millimetres (1.8–2.1 in). The upperside of the wings is golden to orange yellow with a broad black margin on all four wings and a black spot near the centre forewing. Usually these butterflies settles with its wings closed, consequently the black margin of the uppersides of the wings is difficultly visible.

The underside lacks the black borders and is lighter, with a more greenish tint, particularly on the forewings. In the forewing underside is the same dark spot as on the upperside, but often with a light centre; the hindwing underside has a white centre spot, often with a smaller white or dark dot immediately above it. Sometimes, a row of black dots occurs on the underwings' outer margins, corresponding to where the black border ends on the upperside. Females differ from the males in having yellow spots along the black borders on the upperside.

In flight, Colias croceus is easily identifiable by the intense yellow colouring, much brighter than that of the lemon-yellow male common brimstone which also lacks black markings. Like all Colias species they never open their wings at rest.

In about 5% of females, the golden upperside colouration is replaced by a pale cream colour. These females have been distinguished as form helice. The pale form helice does not seem to be distinct, as intermediates exist, and the variation is to some extent related to humidity during development, with dryer conditions producing paler colouration. These pale forms helice can be confused with Berger's clouded yellow (Colias alfacariensis) and the rarer pale clouded yellow (Colias hyale). Even the palest C. croceus tends to have more black on the upperside, however, in particular on the hindwings.

Young caterpillars are yellow-green with a black head. Later they become completely dark green, with a white red-spotted lateral line after the third moult. The pupae are green and have a yellow side stripe.

This species is similar to Colias myrmidone, Colias chrysotheme, Colias erate, Colias hyale, Colias alfacariensis, Colias caucasica, Colias aurorina.

4-5-2018 EL PERELLO, VALENCIA - LITTLE BITTERN (Ixobrychus minutus)


The little bittern or common little bittern (Ixobrychus minutus) is a wading bird in the heron family, Ardeidae. Ixobrychus is from Ancient Greek ixias, a reed-like plant and brukhomai 'to bellow', and minutus is Latin for 'small'.

The little bittern is native to the Old World, breeding in Africa, central and southern Europe, western and southern Asia, and Madagascar. Birds from temperate regions in Europe and western Asia are migratory, wintering in Africa and further south in Asia, while those nesting in the tropics are sedentary. It is rare north of its breeding range.

In Britain there were intermittent reports of breeding in the nineteenth century, and again in 1946 and 1957, but none of these records were proven. The first proven British breeding record is from Yorkshire in 1984, and the second from the Avalon Marshes in Somerset in 2010, by 2017 this species had been present in this area for nine consecutive years.


Carl Linnaeus described the little bittern in 1766. Member of a cosmopolitan superspecies with I. exilis (North and South America), I. sinensis (Asia) and I. dubius (New Guinea, AUS). I. [m.] minutus itself consists of three clearly differentiated subspecies (groups) to which all-species status could be assigned:

I. m. minutus – (Linnaeus, 1766): nominate, found in Europe, Asia, northern Africa; winters in sub-Saharan Africa and southern Asia
I. m. payesii – (Hartlaub, 1858): found in sub-Saharan Africa, resident
I. m. podiceps – (Bonaparte, 1855): found in Madagascar, resident
The Australian little bittern (I. dubius) and the extinct New Zealand little bittern (I. novaezelandiae) were formerly considered subspecies of the little bittern.

Comparative studies, especially on shouting / courtship behavior and genetics, are lacking.


The little bittern has a length of 33–38 centimetres (13–15 in) and a wing span of 52–58 centimetres (20–23 in). It is the smallest of the breeding herons of Europe and is characterised by its tiny size, long and sharp bill and thick neck. The males are distinctively patterned and both sexes show pale forewing panels. The males have black with a faint green sheen on the crown, nape, back, tail and scapulars. The underparts are pale buff and the wing has a pinkish buff oval shaped panel which contrasts with the otherwise black wings and is formed by the inner wing coverts. The underwing is completely whiteish in colour. The female is duller than the male and has brownish black upperparts with paler feather margins visible at close range. The underparts of the female are not as clean as those of the male and are streaked with dark buff and brown. The female's wing panel is less obvious than the male's. The juveniles are duller and more rufous than the females and are more heavily streaked on both their upperparts and underparts, including their wing coverts.

21-4-2018 OKAVANGO DELTA, BOTSWANA - COMMON WARTHOG (Phacochoerus Africus)


The Common warthog (Phacochoerus africanus) is a wild member of the pig family (Suidae) found in sub-Saharan Africa. It is the only pig species that has adapted to grazing and savanna habitats.

Common warthogs are found in sub-Saharan Africa. They live in grasslands, savanna, open bushlands, and woodlands. These animals prefer open areas and avoid rainforests, thickets, cool montane grasslands, and severe deserts.


A warthog has two pairs of tusks protruding from the mouth and curving upwards. The lower pair, which is far shorter than the upper pair, becomes razor-sharp by rubbing against the upper pair every time the mouth is opened and closed. The upper canine teeth can grow to 25.5 cm (10.0 in) long and have a wide elliptical cross-section, being about 4.5 cm (1.8 in) deep and 2.5 cm (0.98 in) wide. A tusk will curve 90° or more from the root, and will not lie flat on a table, as it curves somewhat backward as it grows. The tusks are not used for digging, but are used for combat with other hogs and in defense against predators - the lower set can inflict severe wounds. Common warthog ivory is taken from the constantly growing canine teeth. The tusks, particularly the upper set, work in much the same way as elephant tusks with all designs scaled down. Tusks are carved predominantly for the tourist trade in eastern and southern Africa. The head of the Common warthog is large, with a mane down the spine to the middle of the back. Sparse hair covers the body. Its color is usually black or brown. Tails are long and end with a tuft of hair. Common warthogs do not have subcutaneous fat and the coat is sparse, making them susceptible to extreme environmental temperatures.

21-4-2018 OKAVANGO DELTA, BOTSWANA - AFRICAN STRIPED SKINK (Trachylepis striata)


The African striped skink (Trachylepis striata), commonly called the striped skink, is a species of lizard in the skink family (Scincidae). The species is widespread in East Africa and Southern Africa. It is not a close relation to the Australian striped skink, Ctenotus taeniolatus.

T. striata is brown or bronze-coloured with two yellowish stripes that run lengthwise on either side of the spine. Both sexes grow to a total length (including tail) of 25 cm (9.8 in). Their tails are often missing due to predators.

The African striped skink (Trachylepis striata), or simply the striped skink, is a common species of skink found widely across sub-Saharan Africa. It typically has a sleek, streamlined body with distinctive striping along its sides, which differentiates it from similar species. The coloration and pattern can vary, but generally, it features a combination of brown, grey, and olive tones.

It typically has a sleek, streamlined body with distinctive striping along its sides, which differentiates it from similar species. The coloration and pattern can vary, but generally, it features a combination of brown, grey, and olive tones.

The African striped skink is known for its adaptability to various habitats, ranging from woodlands and savannas to human-altered environments. It primarily feeds on insects and other small invertebrates. It is known for its agility and quick movements, which aid in both foraging for food and evading predators.

The African striped skink usually breeds in the warmer months. They are oviparous, laying eggs which hatch after an incubation period. Details on the exact duration of incubation and specific breeding behaviors are not yet known.

The population of African striped skink is unknown, but it has a wide range and it is common. It is listed as least concern on the IUCN Red List. 

21-4-2018 OKAVANGO DELTA, BOTSWANA - SMITH'S BUSH SQUIRREL (Paraderus Cepapi)


Smith's bush squirrel (Paraxerus cepapi ), also known as the yellow-footed squirrel or tree squirrel, is an African bush squirrel which is native to woodlands of the southern Afrotropics.

Its total length is 350 mm, half of which is tail. This species only weighs 200 g. The coat colour varies throughout the region. In the western and arid parts of its range, it is pale grey, and in the eastern localities, more brown. Its head and legs are a rusty colour. Colouration on the chest varies from yellowish to buff in the east, to white in the west. This squirrel's belly is white. These alert and ever busy creatures carry their long tails extended backwards.


It is found in Angola, Botswana, the DRCongo, Malawi, Mozambique, Namibia, South Africa, Tanzania, Zambia, and Zimbabwe. It is a common rodent which is diurnal by nature.

21-4-2018 OKAVANGO DELTA, BOTSWANA - HADADA IBIS (Bostrychia hagedash)


The Hadada Ibis, Bostrychia hagedash, is a medium-sized bird native to the diverse landscapes of Sub-Saharan Africa. It is characterized by its stout legs and distinctive down-curved bill. The adult Hadada Ibis typically measures around 76 cm in length and weighs approximately 1.2 kg. Both sexes share similar plumage, which is primarily grey to partly brown, with a striking iridescent sheen of green or purple on the wing coverts.

When observing the Hadada Ibis, look for the narrow white stripe across its cheeks, often referred to as the "moustache," though it does not extend to the mouth corners. During the breeding season, the bird sports a red culmen on the upper mandible's basal half and similarly colored upper toe surfaces. Its powerful and broad wings facilitate quick take-offs and agile flight through dense foliage.

The Hadada Ibis thrives in a variety of habitats, including open grasslands, savannas, wetlands, and increasingly in urban environments such as parks, school fields, and residential gardens. It prefers areas with moist and soft soils, which are conducive to its foraging habits.


This species is widespread across Sub-Saharan Africa, with its range extending from Sudan to South Africa. The Hadada Ibis has seen a notable range expansion in southern Africa, attributed to increased tree cover and irrigation in human-altered landscapes.

The Hadada Ibis is known for its social roosting behavior, often in groups atop trees. It is a diurnal bird, vocalizing loudly during morning and evening flights. Its diet consists of insects, millipedes, earthworms, and other small invertebrates, which it hunts using its long, scimitar-like bill to probe the soil. The Hadada Ibis is also appreciated in urban settings for its role in controlling pests on lawns and greens.

The Hadada Ibis is renowned for its loud "haa-haa-haa-de-dah" call, which is particularly prominent during flight or when startled. This call has earned the species its onomatopoeic name. While roosting, a single loud "haaaa" can be heard, and a low growl, akin to a young puppy's, serves as a contact call when foraging.

Monogamous by nature, Hadada Ibises maintain pair bonds year-round. Breeding is timed with the rainy season, with nests constructed as twig platforms in large trees. Both parents incubate the typical clutch of three to four eggs for about 26 days, and the fledglings leave the nest after approximately 33 days.

Hadada Ibises primarily feed on soil invertebrates, which they detect using sensory pits around their bill tips. They are also known to consume snails and small reptiles, providing a natural pest control service in both natural and urban settings.

21-4-2018 OKAVANGO DELTA, BOTSWANA - CHACMA BABOON (Papio ursinus)


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.


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.

21-4-2018 OKAVANGO DELTA, BOTSWANA - ARROW MARKED BABBLER (Turdoides jardineii ssp. tamalakanei)


The arrow-marked babbler, scientifically known as Turdoides jardineii, is a medium-sized bird belonging to the family Leiothrichidae. It measures between 22 to 25 cm in length and tips the scales at a modest 56 to 85 grams. Its plumage is a study in understated elegance, with brownish-grey tones adorning the upper parts and a paler hue below. The feathers on the throat, neck, and head are tipped with white, creating a distinctive pattern from which its name is derived. A striking feature of this bird is its eyes, which boast an outer ring of bright red and an inner circle of either bright yellow or orange. Males and females are visually indistinguishable, while the juveniles can be identified by their brown eyes and less pronounced arrow-shaped markings on the breast.

When attempting to identify the arrow-marked babbler, look for the characteristic white-tipped feathers on the head and neck, as well as the unique coloration of the eyes. The bird's size and the arrow-shaped streaks on the breast are also key identification features.

The arrow-marked babbler is a denizen of the southern Afrotropics, where it favors the subtropical or tropical dry forests, dry savannas, and moist shrublands.


This species has a wide range across the African continent, being found in Angola, Botswana, Burundi, Republic of the Congo, Democratic Republic of the Congo, Eswatini, Gabon, Kenya, Malawi, Mozambique, Namibia, Rwanda, South Africa, Tanzania, Uganda, Zambia, and Zimbabwe.

Arrow-marked babblers are social creatures, living in groups that typically number between three and fifteen individuals, with six being the average. These groups are territorial, with the size of their domain varying according to the number of birds in the group. They are known to forage near the ground, often in the company of other babblers or bulbuls, in search of their varied diet.

The diet of the arrow-marked babbler is quite diverse, including insects, spiders, and occasionally snails and lizards. They also partake in fruits, which they forage for close to the ground.

The arrow-marked babbler is currently listed as Least Concern by the IUCN, indicating that, for now, this species does not face any immediate threat of extinction.

21-4-2018 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.

21-4-2018 OKAVANGO DELTA, BOTSWANA - AFRICAN LEOPARD (JUVENILE) (Panthera pardus pardus)



The African leopard (Panthera pardus pardus) is the nominate subspecies of the leopard, native to many countries in Africa. It is widely distributed in most of sub-Saharan Africa, but the historical range has been fragmented in the course of habitat conversion. Leopards have also been recorded in North Africa as well.

The African leopard exhibits great variation in coat color, depending on location and habitat. Coat color varies from pale yellow to deep gold or tawny, and sometimes black, and is patterned with black rosettes while the head, lower limbs, and belly are spotted with solid black. Male leopards are typically larger and heavier than females.


African leopards inhabited a wide range of habitats within Africa, from mountainous forests to grasslands and savannahs, excluding only extremely sandy deserts. They used to live in most of sub-Saharan Africa, occupying both rainforest and arid desert habitats. African leopards successfully adapted to altered natural habitats and settled environments in the absence of intense persecution and they have often been seen close to major cities. But already in the 1980s, they have become rare throughout much of West Africa. Now, African leopards remain patchily distributed within historical limits. During surveys in 2013, they were recorded in Gbarpolu County and Bong County in the Upper Guinean forests of Liberia. They are rare in North Africa. A relict population persists in the Atlas Mountains of Morocco, in forest and mountain steppe, where the climate is temperate to cold. In 2016, an African leopard was recorded for the first time in a semi-arid area of Yechilay in northern Ethiopia.


In Kruger National Park, male African leopards and females with cubs were more active at night than solitary females. In general, leopards spend their time singly and most active between sunset and sunrise, and kill more prey at this time. They maintain home ranges that usually overlap with each other. Thus, the home range of a male can often overlap with the territories of multiple females. Females live with their cubs in home ranges that overlap extensively and continue to interact with their offspring even after weaning; females may even share kills with their offspring when they can not obtain any prey. Leopards usually hunt on the ground and depend mainly on their acute senses of hearing and vision for hunting. They stalk their prey and try to approach it as closely as possible, typically within 5 m (16 ft) of the target, and, finally, pounce on it and kill it by suffocation. Leopards are known to be excellent climbers and often rest on tree branches during the day, dragging their kills up trees and hanging them there, and descending from trees headfirst. Leopards are also powerful swimmers. They are very agile and can run at over 58 km per hour (36 mph), leap over 6 m (20 ft) horizontally, and jump up to 3 m (9.8 ft) vertically. They produce a number of vocalizations, including grunts, roars, growls, meows, and purrs.


Leopards are carnivores and have an exceptional ability to adapt to changes in prey availability. They have a very broad diet that ranges from dung beetles to adult elands, which can reach 900 kg (2,000 lb). In sub-Saharan Africa, at least 92 prey species have been documented in leopard scat, including rodents, birds, small and large antelopes, hyraxes, hares, and arthropods. In Serengeti National Park, leopards preyed mostly on impalas, both adult and young, and caught some Thomson's gazelles in the dry season. Occasionally, they successfully hunted warthogs, dik-diks, reedbucks, duikers, steenboks, Blue wildebeest and topi calves, jackals, Cape hares, guineafowl, and starlings. In the tropical rainforests of Central Africa, their diet consists of duikers and primates. African leopards were even observed preying on adult Eastern gorillas in the Kisoro area near Uganda's borders with Rwanda and the Democratic Republic of the Congo.


Little is known about the reproductive behavior of African leopards. In general, leopards have polygynandrous (promiscuous) mating system, where both males and females mate with a number of mates. They breed throughout the year. The gestation period lasts for 90-105 days, yielding from 2 to 4 cubs. Females give birth in a cave, crevice among boulders, hollow trees, or thicket. Cubs are born with closed eyes, which open 4 to 9 days after birth. Being extremely vulnerable in the wild, the cubs remain hidden, living in a secluded place, covered with dense vegetation. By the age of 6-8 weeks, the young attain their dark, woolly coat, covered with blurry patches, which serves young leopards as camouflage, allowing them to follow their mother around. Reaching the age of 3 months, the cubs are weaned, accompanying their mother on a hunt. On the whole, they remain with their mother for 18-24 months, after which they leave to find their own territories. Young leopards start breeding when they are between 2 and 3 years old.
