28-5-2019 SOMALISA CAMP, ZIMBABWE - WHITE BACKED VULTURE (Gyps africanus)


The white-backed vulture is a typical vulture, with only down feathers on the head and neck, very broad wings and short tail feathers. It has a white neck ruff. The adult's whitish back contrasts with the otherwise dark plumage. Juveniles are largely dark. This is a medium-sized vulture; its body mass is 4.2 to 7.2 kg (9.3–15.9 lb), it is 78 to 98 cm (31 to 39 in) long and has a 1.96 to 2.25 m (6 ft 5 in to 7 ft 5 in) wingspan.
 
The white-backed vulture occurs from Senegal, Gambia and Mali in the west, throughout the Sahel region to Ethiopia and Somalia in the east, through East Africa into Mozambique, Zimbabwe, Botswana, Namibia and South Africa in the south. It is the most widespread and common vulture in Africa with an estimated range of 24,300,000 km2 (9,400,000 sq mi), but has undergone rapid population declines in recent years.


The white-backed vulture, like many African vultures, has suffered a rapid decline. When it was first assessed in 1988 it was classified as a Least concern species owing to a large range and population. It was reassessed from a Least Concern to Near Threatened species in the 2007 IUCN Red List after the beginnings of a major decline were noticed. In 2012, more information was available about population trends, and the estimates suggested that within the next three generations the white-backed vulture would decrease by 50%. Consequently it was added to the list of Endangered species. In October 2015, it was further uplisted to Critically Endangered because the decline had reach a magnitude that puts the vulture at an extreme risk of extinction.

28-5-2019 SOMALISA CAMP, ZIMBABWE - SOUTHERN LION (MALE) (Panthera leo ssp. melanochaita)


The Southern lion is a lion subspecies from Southern and East Africa. In this region, lion populations were referred to by several regional names, including Katanga lion, Transvaal lion, Kalahari lion, Southeast African lion, Southwest African lion, Masai lion, Serengeti lion, Tsavo lion, and Uganda lion. It has also been referred to as 'Eastern-Southern African lion', 'Southern lion', and as 'southern subspecies'.

The fur of Southern lions varies in color from light buff to dark brown. They have rounded ears and a black tail tuft. Mane color varies from sandy, tawny, isabelline, and light reddish yellow to dark brown and black. Mane length varies from short to extending to knee joints and under the belly. Lions without a mane were observed in the Tsavo area. Mane development is related to age: older males have more extensive manes than younger ones; manes continue to grow up to the age of four to five years, long after lions become reproductively mature. Males living in the Kenyan highlands develop heavier manes than lions in the more humid and warmer lowlands of eastern and northern Kenya. White lions have occasionally been encountered in and around South Africa's Kruger National Park and the adjacent Timbavati Private Game Reserve. Their whitish fur is a rare morph caused by a double recessive allele. It has normal pigmentation in the eyes and skin. They were removed from the wild in the 1970s, thus decreasing the white lion gene pool.


Southern lions are found in East and Southern Africa. They are grouped into three clades. Lions, which can be grouped into the North East African clade are found in Somalia, Northern Kenya, and Ethiopia. Lions, which can be grouped into the South East African clade are found in Southern Kenya, Western DRC, Tanzania, Mozambique, Malawi, Zambia, southern Namibia, and South Africa, with a larger hybridization zone to the southwestern lion clade in the Kruger National Park area (Great Limpopo Transfrontier Park). Lions, which can be grouped into the South West African clade are found in Angola, Northern Namibia, Northern Botswana, and western Zimbabwe, extending southeast into the Tuli block. There is a larger hybridization zone in the southeastern clade around the Kruger National Park.


Little is known about the behavior of Southern lions. In general, lions can be active at any time of the day but their activity generally peaks after dusk with a period of socializing and grooming. Most hunting often takes place at dusk. Apart from that African lions spend much of their time resting. They rest in order to save energy, in the absence of prey, or to escape the midday heat. African lions are highly social animals, gathering in groups or prides, which include up to 3 male lions and multiple lionesses with their young. Prides are defended by males, who patrol and mark the territory. However, there's harsh competition between males for the territory and position in the pride. In a case, if another male overcomes the leading male of the pride, he usually kills all cubs, sired by the previous male. Meanwhile, males do not tend to hunt due to their slow speed and eye-catching appearance. Instead, hunting is left to females of the pride, who hunt in groups, cooperating with each other during their hunting trips. The females are excellent hunters: they are faster and more agile than males, able to hunt down animals that are much bigger and faster than them. Lions have a large repertoire of vocalizations. Most of them are variations of growling, snarling, meowing, and roaring. Other sounds produced include purring, puffing, bleating, and humming. Roaring is used for advertising their presence. Lions most often roar at night, a sound that can be heard from a distance of 8 km (5 mi).
