5-6-2019 LINYANTI CAMP, BOTSWANA - COMMON WATERBUCK (MALE) (Kobus ellipsiprymnus ssp. ellipsiprymnus)
The waterbuck (Kobus ellipsiprymnus) is a large antelope found widely in sub-Saharan Africa. It is placed in the genus Kobus of the family Bovidae. It was first described by Irish naturalist William Ogilby in 1833. Its 13 subspecies are grouped under two varieties: the common or ellipsiprymnus waterbuck and the defassa waterbuck. The head-and-body length is typically between 177 and 235 cm (70 and 93 in) and the typical height is between 120 and 136 cm (47 and 54 in). In this sexually dimorphic antelope, males are taller and heavier than females. Males reach roughly 127 cm (50 in) at the shoulder, while females reach 119 cm (47 in). Males typically weigh 198–262 kg (437–578 lb) and females 161–214 kg (355–472 lb). Their coat colour varies from brown to grey. The long, spiral horns, present only on males, curve backward, then forward, and are 55–99 cm (22–39 in) long.
5-6-2019 LINYANTI CAMP, BOTSWANA - AFRICAN WATTLED LAPWING (Vanellus senegallus)
The African wattled lapwing (Vanellus senegallus), also known as the Senegal wattled plover or simply wattled lapwing, is a large lapwing, a group of largish waders in the family Charadriidae. It is a resident breeder in most of sub-Saharan Africa outside the rainforests, although it has seasonal movements.
These are conspicuous and unmistakable birds. They are large brown waders with a black crown, white forehead and large yellow facial wattles. The tail is white, tipped black, and the long legs are yellow.
In flight, the upperwings have black flight feathers and brown coverts separated by a white bar. The underwings are white with black flight feathers. The African wattled lapwing has a loud peep-peep call.
This species is a common breeder in wet lowland habitats, especially damp grassland. It often feeds in drier habitats, such as golf courses, picking insects and other invertebrates from the ground. It lays three or four eggs on a ground scrape.
The African wattled lapwing is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) applies.

5-6-2019 LINYANTI CAMP, BOTSWANA - SENEGAL COUCAL (Centropus senegalensis)
The Senegal coucal, Centropus senegalensis, is a medium-sized bird within the cuckoo order, Cuculiformes. It boasts a striking appearance with a black crown, nape, upper parts, bill, legs, and elongated tail. The eyes of this species are a captivating red, while the wings present a rich chestnut hue. The underparts are a creamy white, accented with blackish barring on the flanks.
When identifying the Senegal coucal, look for its black upper body and tail, contrasting with chestnut wings and creamy underparts. The red eyes are a distinctive feature, as is the barring on the flanks. Juveniles may appear browner with more pronounced barring and streaking.
This bird favors grassy environments interspersed with trees, such as bushlands and savannahs, providing it with ample cover and foraging opportunities.
The Senegal coucal's range spans across central and southern Africa, south of the Sahara Desert. It can be found from Senegal and Gambia in the west, across to Ethiopia and Kenya in the east, and reaching down to Angola and Congo in the south. A separate population resides in southern Africa, particularly around Zambia, Zimbabwe, and northern Botswana.

5-6-2019 LINYANTI CAMP, BOTSWANA - AFRICAN BLACK WINGED KITE (Elanus caeruleus ssp. caeruleus)
The black-winged kite (Elanus caeruleus), also known as the black-shouldered kite (not to be confused with the closely-related Australian species of the same name), is a small diurnal bird of prey in the family Accipitridae best known for its habit of hovering over open grasslands in the manner of the much smaller kestrels. This Palearctic and Afrotropical species was sometimes combined with the Australian black-shouldered kite (Elanus axillaris) and the white-tailed kite (Elanus leucurus) of North and South America which together form a superspecies. This kite is distinctive, with long wings; white, grey and black plumage; and owl-like forward-facing eyes with red irises.
The owl-like behaviour is even more pronounced in the letter-winged kite (Elanus scriptus), a nocturnal relative in Australia. Although mainly seen on plains, they are sometimes seen on grassy slopes of hills in the higher elevation regions of Asia. They are not migratory, but show nomadism in response to weather and food availability. They are well adapted to utilize periodic upsurges in rodent populations and can raise multiple broods in a single year unlike most birds of prey. Populations in southern Europe have grown in response to human activities, particularly agriculture and livestock rearing.
The black-winged kite is a species primarily of open land and semi-deserts in sub-Saharan Africa and tropical Asia, but it has a foothold within Europe in Spain and Portugal. The species range appears to be expanding in southern Europe and possibly in West Asia. The first records of breeding in Europe were in the 1860s and since then they have become more widespread and populations are on the rise. It is thought that land-use changes, particularly agriculture and pastureland have helped the species.The species has expanded its range in southern Europe.
Several geographic populations have been named as subspecies and these include the nominate subspecies which occurs in Spain, Africa and Arabia. The subspecies vociferus is found east of this range across South Asia and into Southeast Asia. Along Sumatra, Java, Borneo and the Philippines subspecies hypoleucus (sometimes considered a full species) includes the population wahgiensis described from New Guinea. Subspecies sumatranus is not always recognized. The white-tailed kite and the black-shouldered kite were formerly included with this species but have since been treated as separate species.
Although found mainly on the plains they have been seen at higher altitudes in Sikkim (3,650 m (11,980 ft)), the Nilgiris (Doddabetta, 2,670 m (8,760 ft))[23] and Nagaland (2,020 m (6,630 ft)).
They are said to be winter visitors in some parts of their range such as the Western Ghats.
4-6-2019 LINYANTI CAMP, BOTSWANA - HIPPOPOTAMUS (Hippopotamus amphibius)
%2021.jpg)
The hippopotamus (Hippopotamus amphibius; /ˌhɪpəˈpɒtəməs/; pl.: hippopotamuses), often shortened to hippo (pl.: hippos), further qualified as the common hippopotamus, Nile hippopotamus and river hippopotamus, is a large semiaquatic mammal native to sub-Saharan Africa. It is one of only two extant species in the family Hippopotamidae, the other being the pygmy hippopotamus (Choeropsis liberiensis or Hexaprotodon liberiensis). Its name comes from the Ancient Greek for "river horse" (ἱπποπόταμος).
After elephants and rhinoceroses, the hippopotamus is the next largest land mammal. It is also the largest extant land artiodactyl. Despite their physical resemblance to pigs and other terrestrial even-toed ungulates, the closest living relatives of the hippopotamids are cetaceans (whales, dolphins, porpoises, etc.), from which they diverged about 55 million years ago.
