4-6-2019 LINYANTI CAMP, BOTSWANA - AFRICAN SAVANNA ELEPHANT (Loxodonta Africana)
The African bush elephant (Loxodonta africana), also known as the African savanna elephant, is a species of elephant native to sub-Saharan Africa. It is one of three extant elephant species and, along with the African forest elephant, one of two extant species of African elephant. It is the largest living terrestrial animal, with fully grown bulls reaching an average shoulder height of 3.04–3.36 metres (10.0–11.0 ft) and a body mass of 5.2–6.9 tonnes (5.7–7.6 short tons); the largest recorded specimen had a shoulder height of 3.96 metres (13.0 ft) and an estimated body mass of 10.4 tonnes (11.5 short tons). The African bush elephant is characterised by its long prehensile trunk with two finger-like processes; a convex back; large ears which help reduce body heat; and sturdy tusks that are noticeably curved. The skin is grey with scanty hairs, and bending cracks which support thermoregulation by retaining water.
The African bush elephant inhabits a variety of habitats such as forests, grasslands, woodlands, wetlands and agricultural land. It is a mixed herbivore feeding mostly on grasses, creepers, herbs, leaves, and bark. The average adult consumes about 150 kg (330 lb) of vegetation and 230 L (51 imp gal; 61 US gal) of water each day. A social animal, the African bush elephant often travels in herds composed of cows and their offspring. Adult bulls usually live alone or in small bachelor groups. During the mating season, males go through a process called musth, a period of high testosterone levels and heightened aggression. For females, the menstrual cycle lasts three to four months, and gestation around 22 months, the longest of any mammal.
Since 2021, the African bush elephant has been listed as Endangered on the IUCN Red List. It is threatened foremost by habitat destruction, and in parts of its range also by poaching for meat and ivory. Between 2003 and 2015, the illegal killing of 14,606 African bush elephants was reported by rangers across 29 range countries. Chad is a major transit country for smuggling of ivory in West Africa. This trend was curtailed by raising penalties for poaching and improving law enforcement. Poaching of the elephant has dated back to the 1970s and 80s, which were considered the largest killings in history. In human culture, elephants have been extensively featured in literature, folklore and media, and are most valued for their large tusks in many places.

3-6-2019 LINYANTI CAMP, BOTSWANA - KALAHARI YELLOW BILLED HORNBILL (Tockus leucomelas ssp. leucomelas)
%2020.jpg)
The Southern Yellow-billed Hornbill, known scientifically as Tockus leucomelas, is a medium-sized bird, with a length ranging from 48 to 60 centimeters and a weight between 132 and 242 grams. Its most striking feature is the long, down-curved yellow beak, which is disproportionately large compared to its body, making up to one-sixth of its body length. Males boast a longer beak, averaging 90 millimeters, while females have a slightly shorter one, averaging 74 millimeters. The species exhibits sexual dimorphism, with males generally larger than females. The bird's plumage is a combination of white, grey, and black, with the white belly and grey neck contrasting against the black back adorned with white spots and stripes. The eyes are typically yellow, though brown variations exist, and the skin around the eyes and malar stripe is pinkish.
To identify the Southern Yellow-billed Hornbill, look for the long yellow beak and modest-sized casque that covers almost the entire length of the beak in males. The bird's white belly, grey neck with spots, and black back with white markings are also distinctive. The male's larger size and longer beak are reliable indicators for sex differentiation in the field.
%2021.jpg)
This hornbill species is a common and widespread resident of the dry thornveldt and broad-leafed woodlands, often seen along roads and watercourses. They show a preference for acacia and broadleaved woodlands when available.
The Southern Yellow-billed Hornbill is near-endemic to the dry savannas of southern Africa, with its range extending from Angola and Namibia in the west to Mozambique and KwaZulu-Natal in the east, including Botswana, Zimbabwe, and northern South Africa.
Active during the day, these birds are often solitary, but may form couples or small groups, especially during breeding or nesting seasons, or when local migration occurs during the dry season. They are ground foragers, not digging but rather overturning debris to find food. They are sedentary but may roam in search of sustenance during dry spells. Monogamous pairs defend their territories with elaborate displays.
The Southern Yellow-billed Hornbill's vocal repertoire includes a piercing cry, whistles, grunts, and cackles. These calls are used for territory demarcation and long-distance communication, often accompanied by physical displays.
Their diet consists mainly of arthropods like termites, beetles, larvae, grasshoppers, and caterpillars, supplemented by small mammals, berries, fruits, nuts, and eggs from other species. They use their beak as forceps to grasp and toss food into their throat, with serrated inner edges aiding in crushing and fragmenting their prey.
3-6-2019 LINYANTI CAMP, BOTSWANA - GREATER BLUE EARED STARLING (Lamprotornis chalybaeus)
The greater blue-eared starling, or Lamprotornis chalybaeus, is a striking bird adorned in glossy blue-green plumage with a purple-blue belly and a distinctive blue ear patch. This bird measures approximately 22 cm in length and sports a short tail. The iris of this species is a vivid yellow or orange, adding to its captivating appearance. Both sexes exhibit similar coloration, though juveniles can be distinguished by their duller feathers and blackish-brown underparts.
When identifying the greater blue-eared starling, look for its glossy blue-green upperparts and purple-blue belly. The blue ear patch is a key feature, along with its bright yellow or orange iris. Juveniles are less lustrous and have darker underparts. This species can be confused with the lesser blue-eared starling, but the latter's blue belly does not extend forward of the legs.
The greater blue-eared starling is commonly found in open woodland environments, where it thrives and breeds.
This bird has a broad range across the African continent, from Senegal in the west, stretching east to Ethiopia, and then southward through eastern Africa to northeastern South Africa and Angola. It is known to undertake seasonal migrations within this range.
The greater blue-eared starling is a highly social bird, often seen in large flocks that may include other starling species. It is also known to roost communally in reedbeds, thorn bushes, or acacia trees, sometimes sharing these spaces with other birds.
The vocal repertoire of the greater blue-eared starling includes a variety of musical and grating calls. A commonly heard call is a nasal "squee-ar," which is quite distinctive.
Breeding pairs of greater blue-eared starlings make their nests in tree holes, which can be naturally occurring or previously excavated by woodpeckers or barbets. They are also known to utilize the large stick nests of the sacred ibis or Abdim's stork. Their nests typically contain three to five greenish-blue eggs adorned with brown or purple spots. These eggs hatch after about 13–14 days, and the fledglings leave the nest approximately 23 days post-hatching. The species is occasionally parasitized by the great spotted cuckoo and, less frequently, by the greater honeyguide.
An omnivorous bird, the greater blue-eared starling's diet is predominantly insectivorous, foraging mainly on the ground for a variety of invertebrates. It also consumes seeds and berries, with a particular fondness for figs. Additionally, these starlings are known to perch on livestock, picking off insects disturbed by the animals and sometimes removing ectoparasites.
The IUCN Red List classifies the greater blue-eared starling as Least Concern, indicating that the species does not currently face any significant threats to its survival.
A medium-sized iridescent blue-green glossy starling with a dark ear-patch and contrasting royal blue to violet flanks and belly. Pairs and small groups occupy savanna, where they feed on the ground and in trees on fruit and insects; occasionally up to 300 may gather at fruiting trees. Often the species scavenges from people. It gives a cat-like nasal “squuee-aar” contact call that is distinctive.
The similar Lesser Blue-eared Starling differs from Greater Blue-eared Starling by being smaller with a more compact head and finer bill, by having a smaller ear-patch, and by preferring broadleaf woodland. The Cape Starling differs from the “blue-eared” starlings by having greener ear-patches, belly, and flanks.
3-6-2019 LINYANTI CAMP, BOTSWANA - AFRICAN JOKER BUTTERFLY (Byblia anvatara)
Byblia anvatara, the common joker, is a butterfly of the family Nymphalidae, found in Sub-Saharan Africa.
Wingspan: 38–43 mm in males and 40–45 mm in females. Its flight period is year round.
Larvae feed on Tragia glabrata and Dalechampia capensis.
3-6-2019 LINYANTI CAMP, 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 (14 in), half of which is tail; weight 200 g (7.1 oz). 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.

3-6-2019 LINYANTI CAMP, BOTSWANA - HOLUB'S GOLDEN WEAVER (Ploceus xanthops)
%2020.jpg)
Holub's golden weaver (Ploceus xanthops), also known as the African golden weaver, is a species of bird in the family Ploceidae. The common name commemorates the Czech naturalist Emil Holub. It is found from Gabon to Uganda and Kenya, south to northern Namibia, northern Botswana and eastern South Africa. They have a yellow on their heads and light yellow eyes. They live for four years. Their usual call sounds like "chichi-chichi-chi-squirr ski-wee" but there is some variation from regions so some contact calls are a short "chirp.
Males differentiate from the females because of their full yellow heads, bright greenish-yellow body and the bit of orange under their chins that continues to the upper breast. The coloring on the females are duller and they only have the yellow coloring on the forehead. The males and the females share several similar characteristics, dull brown wings on the upper portion and then the lower portion having a yellow coloring. As they have light yellow eyes, black bills and pink legs. When the birds are younger they are a dull olive color with only the tail, chin and throat having the yellow coloring. Their eyes are dark brown and their bill is a pale brown.
%2021.jpg)
They live in seventeen countries which are Angola, Botswana, Burundi, Congo, The Democratic Republic of the Congo, Eswantini, Gabon, Kenya, Malawi, Mozambique, Namibia, Rwanda, South Africa, United Republic of Tanzania, Uganda, Zambia and Zimbabwe. They live in areas that are inland from freshwater which includes forests, savannas, shrublands, grasslands, and wetlands.[5] They cover a range of different habitats which includes bushy areas with tall grass. They can also be found on forest margins or the side of a stream. From East South Africa to West Angola they can be found on the coast. There is not much research so they are assumed to be sedentary. They live at elevations of 1,200 to 2,300 meters. They do not migrate for seasons and the furthest distance recorded was ten kilometers.
The Holub's Golden Weaver is omnivorous and eats a diet of invertebrate fruits, seed and nectar. The insects include beetle larvae, termites, grasshoppers, praying mantis, tabanid flies and spiders. The fruit includes guavas, figs and rhus pyroides. The seeds of grass and exocite pins along with the nectar of ruttya and erythrina. They will sometimes eat the petals of flowers as well.
%2022.jpg)
They are monogamous couples that breed anytime between the months of January–April but they start as early as September in South Africa, Zambia and Malawi. Breeding happens in colonies of two to three territorial males. Male birds perch beside a female, make specific movements and sing a song stretch (song that changes the speed or duration of an audio signal without affecting its pitch). The males build the nest that is two to two and a half meters up from tall bushes or reeds. Usually this is done over water and the females make the lining. Researchers have also found old nests from Brown Firefinch, White-collared Oliveback and Zebra Waxbill. They lay clutches of eggs that range from one to three that range from being a solid pink, blue or white to having red and lilac freckles. The incubation time is fourteen to fifteen days and after hatching they spend nineteen to twenty two days in the nest where they are fed by both parents.
3-6-2019 LINYANTI CAMP, BOTSWANA - CRESTED FRANCOLIN (Ortygornis sephaena ssp. zambesiae)
%2020.jpg)
The crested francolin, known scientifically as Ortygornis sephaena, is a distinguished member of the Phasianidae family. This bird is adorned with a notable crest, which gives it its common name.
When attempting to identify the crested francolin, look for its characteristic crest and the overall brown plumage with intricate patterns that provide excellent camouflage in its natural habitat.
The crested francolin is a bird of southern Africa, where it frequents a variety of habitats, adapting well to its surroundings.
This species is widely distributed across southern Africa, indicating a healthy and stable population in this region.
Observations of the crested francolin's behavior reveal a bird that is well-adapted to its environment, exhibiting typical behaviors of the Phasianidae family.
3-6-2019 LINYANTI CAMP, BOTSWANA - LITTLE BEE-EATER (Merops pasillas)
The little bee-eater (Merops pusillus ) is a near passerine bird species in the bee-eater family, Meropidae. They are residents in much of Sub-Saharan Africa. They should not be confused with the little green bee-eater (Merops orientalis ). Migration is limited to seasonal movements depending on rainfall patterns.
Members of this species, like other bee-eaters, are rich and brightly-coloured slender birds. They have green upper parts, yellow throats, black gorgets, and rich brown upper breasts fading to buffish ochre on the belly. Their wings are green and brown, and their beaks are black. They reach a length of 15–17 cm, which makes them the smallest African bee-eater. Sexes are alike. Often silent, their call is a soft "seep."
These are abundant and tame birds, familiar throughout their range. There have been estimated to be between 60-80 million little bee-eaters. They breed in open country with bushes, preferably near water. Just as the name suggests, bee-eaters predominantly eat insects, especially bees, wasps and hornets, who are caught in the air by sorties from an open perch. This species often hunts from low perches, maybe only a metre or less high. Before eating their meal, a bee-eater removes the sting by repeatedly hitting the insect on a hard surface.
Unlike most bee-eaters, these are solitary nesters, making a tunnel in sandy banks, or sometimes in the entrance to an Aardvark den. They lay 4 to 6 spherical white eggs. Both the male and the female take care of the eggs. These birds roost communally, lined up on a tree branch.
