7-4-2018 THORNYBUSH LODGE, SOUTH AFRICA - STRIPED KINGFISHER (Halcyon chelicuti)
%2021.jpg)
The Striped Kingfisher, known scientifically as Halcyon chelicuti, is a member of the tree kingfisher subfamily. It is a small, robust bird, with a general length ranging from 16 to 18 cm. The upper parts of the adult are predominantly greyish brown, while the lower back, secondary flight feathers, and tail boast a striking metallic blue, which is particularly visible in flight. The underparts are off-white, with varying degrees of buff and brown streaking across the subspecies.
When perched, the Striped Kingfisher may appear rather inconspicuous, but its flight reveals a white patch at the base of the primary flight feathers and a black border along the wing linings. Males can be identified by a black bar at the base of the primaries. The head is streaked dark brown, with a buffy grey or brownish background depending on the sex. A black line runs through the eyes and around the back of the neck, sitting above a white collar. The bill is blackish above and reddish-orange below, with the lower mandible being dull red in juveniles.
The Striped Kingfisher favors woodlands, thorn scrub, dry bush, and open savannas, but it tends to avoid densely forested areas, intensive farmlands, and extreme deserts.
This species is found throughout Sub-Saharan Africa, with two subspecies: H. c. chelicuti occupying most of the range, and H. c. eremogiton residing in the northern desert regions from central Mali to eastern Sudan.

Highly territorial, the Striped Kingfisher defends an area that may encompass up to three hectares and contain around 100 tall trees. It is known to chase away intruders, including other kingfishers, shrikes, doves, and rollers. The bird surveys its territory from a treetop, singing from before dawn until after midday.
The call of the Striped Kingfisher is a high-pitched, piercing "cheer-cherrrrrr" or a far-carrying "KEW, kerrrrrrrrr," with the latter featuring a descending trill. This call is often part of a dusk display involving wing-opening.
Breeding pairs engage in a display of sitting opposite each other, flicking their wings while singing. They nest in disused woodpecker or barbet holes, with both sexes incubating by day and only the female by night. The male feeds the female during this period. The species is mainly monogamous, though instances of polyandry have been observed.
The northern subspecies, H. c. eremogiton, can be distinguished by its grey-brown crown and mantle and almost unstreaked underparts.
The diet primarily consists of grasshoppers, other large insects, and occasionally small lizards, snakes, and rodents. The Striped Kingfisher hunts from a perch, swooping down to capture prey, which is then beaten before being swallowed.
With an extensive range estimated at 13 million square kilometers and a large population, the Striped Kingfisher is classified as Least Concern on the IUCN Red List. There is no indication of significant population decline to warrant a higher threat category.
7-4-2018 THORNYBUSH LODGE, SOUTH AFRICA - SOUTHERN WHITE RHINOCEROS (Ceratotherium simum ssp simum)
The southern white rhinoceros or southern white rhino (Ceratotherium simum simum) is one of the two subspecies of the white rhinoceros (the other being the much rarer northern white rhinoceros). It is the most common and widespread subspecies of rhinoceros.
The southern white rhinoceros is the nominate subspecies; it was given the scientific name Ceratotherium simum simum by the English explorer William John Burchell in the 1810s. The subspecies is also known as Burchell's rhinoceros (Ceratotherium simum burchellii) after Burchell and Oswell's rhinoceros (Ceratotherium simum oswellii) after William Cotton Oswell, respectively. However, these are considered synonyms of its original scientific name.
Ceratotherium simum kiaboaba (or Rhinoceros kiaboaba), also known as straight-horned rhinoceros, was proposed as a different subspecies (or species) found near Lake Ngami and north of the Kalahari Desert. However, it is now considered part of the southern white rhinoceros and ranges throughout southern Africa.
Lifespan is up to 50 years in the wild.
The southern white rhinoceros is one of largest and heaviest land animals in the world. It has an immense body and large head, a short neck and broad chest. Females weigh around 1,600–1,700 kg (3,530–3,750 lb) and males around 2,000–2,300 kg (4,410–5,070 lb), with specimens of up to 3,600 kilograms (7,940 lb) considered reliable, and larger sizes up to 4,500 kg (9,920 lb) claimed but not verified.[3][4][5][6][7][8] The head-and-body length is 3.35–4 m (11.0–13.1 ft) and a shoulder height of 160–186 cm (5.25–6.10 ft).[4][7] It has two horns on its snout. The front horn is larger than the other horn and averages 60 cm (24 in) in length and can reach 166 cm (65 in) in females.[9][7] Females usually have longer but thinner horns than the males, who have larger but shorter ones. The southern white rhinoceros also has a prominent muscular hump that supports its large head. The colour of this animal can range from yellowish brown to slate grey. Most of its body hair is found on the ear fringes and tail bristles, with the rest distributed sparsely over the rest of the body. The southern white rhino has a distinctive flat, broad mouth that is used for grazing. Southern white rhinos are strictly herbivores (graminivores) that feed on short grasses.
8-4-2018 THORNYBUSH LODGE, SOUTH AFRICA - AFRICAN LEOPARD (MALE ) (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 colour 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 larger, averaging 58 kg (128 lb) with 90 kg (200 lb) being the maximum weight attained by a male. Females weigh about 37.5 kg (83 lb) on average.
The African leopard is sexually dimorphic; males are larger and heavier than females. Between 1996 and 2000, 11 adult leopards were radio-collared on Namibian farmlands. Males weighed 37.5 to 52.3 kg (83 to 115 lb) only, and females 24 to 33.5 kg (53 to 74 lb). The heaviest known leopard weighed about 96 kg (212 lb), and was recorded in South West Africa.

7-4-2018 THORNYBUSH LODGE, SOUTH AFRICA - WHITE CRESTED HELMETSHRIKE (Prinops plumatus)
The white-crested helmetshrike (Prionops plumatus ), also known as the white helmetshrike, is a species of passerine bird in the Vanga family Vangidae, formerly usually included in the Malaconotidae.
It is found in Angola, Benin, Botswana, Burkina Faso, Burundi, Cameroon, Central African Republic, Chad, Democratic Republic of the Congo, Ivory Coast, Eritrea, Eswatini, Ethiopia, Gambia, Ghana, Guinea, Guinea-Bissau, Kenya, Malawi, Mali, Mauritania, Mozambique, Namibia, Niger, Nigeria, Rwanda, Senegal, Sierra Leone, Somalia, South Africa, Sudan, Tanzania, Togo, Uganda, Zambia, and Zimbabwe.Its natural habitats are subtropical or tropical dry forests, dry savanna, moist savanna, and subtropical or tropical dry shrubland.
It is a gregarious bird and is found in small, active parties that are always on the move as they forage among the foliage or on the ground. They chatter noisily to one another as they move through their territory.
8-4-2018 THORNYBUSH LODGE, SOUTH AFRICA - AFRICAN LION (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 yellow-billed stork (Mycteria ibis), sometimes also called the wood stork or wood ibis, is a large African wading stork species in the family Ciconiidae. It is widespread in regions south of the Sahara and also occurs in Madagascar.
The yellow-billed stork (Mycteria ibis ), sometimes also called the wood stork or wood ibis, is a large African wading stork species in the family Ciconiidae. It is widespread in regions south of the Sahara and also occurs in Madagascar.
The yellow-billed stork has appeared on postage stamps in several African countries.
%2022.jpg)
The yellow-billed stork is closely related to three other species in the genus Mycteria: the American woodstork (Mycteria americana), the milky stork (Mycteria cinerea) and the painted stork (Mycteria leucocephala). It is classified as belonging to one clade with these three other species because they all display remarkable homologies in behavior and morphology. In one analytical study of feeding and courtship behaviours of the wood-stork family, M.P. Kahl attributed the same general ethology to all members of the genus Mycteria, with relatively few species-specific variations. These four species are collectively referred to as the wood-storks, which should not be confused with one alternative common name (wood-stork) for the yellow-billed stork.
Before it was established that the yellow-billed stork was closely related to the American wood stork, the former was assigned to the genus Ibis, together with the milky stork and painted stork. However, the yellow-billed stork has actually long been recognised as a true stork and along with the other 3 related stork species, it should not strictly be called an ibis.

5-4-2018 THORNYBUSH KRUGER, SOUTH AFRICA - BLACK RHINOCEROS (Diceros bicornis)
The southern black rhinoceros, southern hook-lipped rhinoceros or Cape rhinoceros (Diceros bicornis bicornis) is an extinct subspecies of the black rhinoceros that was once abundant in South Africa from the Cape Province to Transvaal, southern Namibia, and possibly also Lesotho and southern Botswana. Zoos, animal sanctuaries and conservation centers use this same scientific name as an indicating reference to the surviving south-central black rhinoceros. This former species was brought to extinction by excessive hunting and habitat destruction around 1850.
D. bicornis bicornis was the largest of all black rhino subspecies. While the differentiation of subspecies is mostly based on skull and body proportions, as well as details of the dentition, the external appearance of the southern subspecies is not exactly known because no photos exist. The skull was the largest of any known subspecies and proportionally large compared to the body. The limbs were short but slender and the skin folds were probably only weakly pronounced.
