27-5-2019 SOMALISA CAMP, ZIMBABWE - TAWNY FLANKED PRINIA (Prinia subflava)


The tawny-flanked prinia (Prinia subflava) is a small passerine bird belonging to the genus Prinia in the family Cisticolidae, a family of Old World warblers. It is widespread and common in most parts of Africa south of the Sahara. The plain prinia (P. inornata) of southern Asia was formerly included in this species but is now usually considered to be a separate species.

The tawny-flanked prinia was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it with the wagtails in the genus Motacilla and coined the binomial name Motacilla subflava. The specific epithet combines the Latin sub meaning "beneath" or "somewhat" with flavus meaning "yellow". Gmelin based his account on a hand coloured engraving by François-Nicolas Martinet that was published to accompany the Comte de Buffon's multi-volume work, the Histoire Naturelle des Oiseaux. The tawny-flanked prinia is now one of 30 species placed in the genus Prinia that was introduced by the American naturalist Thomas Horsfield in 1821.


The tawny-flanked prinia is 11–12 cm (4.3–4.7 in) in length with a long, narrow, graduated tail and a fairly long, slender bill. The tail is often held erect or waved from side to side. The upperparts are grey-brown with rufous-brown edges to the flight feathers and a rufous tinge to the rump. The throat and breast are whitish while the flanks and vent are warm buff. There is a whitish stripe over the eye and the lores are dark. The tail feathers have a white tip and a dark subterminal band.


The sexes are similar in appearance. Non-breeding birds have a longer tail than breeding birds. Juveniles have pale yellow underparts and a yellowish bill. There are many recognised subspecies.

The call is short, wheezy and rapidly repeated. The song is a monotonous series of shrill notes. The male often sings from an exposed perch.

The pale prinia (P. somalica) of North-east Africa is similar but paler and greyer with whitish flanks. It inhabits drier, more open habitats than the tawny-flanked prinia. The river prinia (P. fluviatilis) of West Africa is also paler and greyer and has a longer tail. It is restricted to waterside vegetation.


There are ten subspecies distributed across most parts of sub-Saharan Africa except for the driest and wettest areas. It is absent from much of the Congo Basin, southern Namibia, south-west Botswana and the western half of South Africa. It is found amongst shrubs and grass in a variety of habitats including woodland, savanna and cultivated areas. It adapts well to man-made habitats and is not considered to be threatened.

It feeds on insects and other invertebrates. It forages in small flocks which move through shrubs and undergrowth.

The nest is purse-shaped and made of strips of grass woven together. It is built one to two metres above the ground. Two to four eggs are laid; they are variable in ground colour and usually have brown or purple spots or blotches.

27-5-2019 SOMALISA CAMP, ZIMBABWE - SOUTHERN LION (MALE) (Panthera leo ssp. melanochaita)


Panthera leo melanochaita is a lion subspecies in Southern and East Africa. In this part of Africa, lion populations are regionally extinct in Lesotho, Djibouti and Eritrea, and are threatened by loss of habitat and prey base, killing by local people in retaliation for loss of livestock, and in several countries also by trophy hunting. Since the turn of the 21st century, lion populations in intensively managed protected areas in Botswana, Namibia, South Africa and Zimbabwe have increased, but declined in East African range countries. In 2005, a Lion Conservation Strategy was developed for East and Southern Africa.

Results of a phylogeographic study indicate that lion populations in southern and eastern Africa form a major clade distinct from lion populations in West Africa, Central Africa and Asia. In 2017, the Cat Classification Task Force of the IUCN Cat Specialist Group subsumed lion populations according to the major clades into two subspecies, namely P. l. leo and P. l. melanochaita. Within P. l. melanochaita three subclades are clearly distinguishable. One from northeastern Africa, another one from southwestern Africa and a third one from southeastern Africa.

The type specimen for P. l. melanochaita was a black-maned lion from the Cape of Good Hope, known as the Cape lion. Phylogeographic analysis of lion samples from Gabon and the Republic of the Congo indicate their close genetic relation to P. l. melanochaita samples from Namibia and Botswana. It has been referred to as the Southern lion, Southern African lion, East-Southern African lion and the "southern subspecies".


The Serengeti and Maasai Mara National Parks and Selous Game Reserve are lion strongholds in East Africa with stable lion populations
In East and Southern Africa, lion populations declined in:

In Ethiopia, where lion populations declined since at least the early 20th century due to trophy hunting by Europeans, killing of lions by local people out of fear, for illegal sale of skins and during civil wars.[40] As of 2009, between seven and 23 lions were estimated to live in Nechisar National Park located in the Ethiopian Highlands. This small protected area is encroached by local people and their livestock. In 2012, lions were documented in cloud forest habitat of Kafa Biosphere Reserve.

Somalia since the early 20th century. Intensive poaching since the 1980s and civil unrest posed a threat to lion persistence.
Uganda to near extinction in the 20th century. In 2010, the lion population in Uganda was estimated at 408 ± 46 individuals in three protected areas including Queen Elizabeth, Murchison Falls and Kidepo Valley National Parks. Other protected areas in the country probably host less than 10 lions. Lions in Queen Elizabeth National Park form a contiguous population with lions in Virunga National Park.


Kenya in the 1990s due to poisoning of lions and poaching of lion prey species. At least 108 lions were killed between 2001 and 2006 in the Amboseli−Tsavo West−Tsavo East National Park network. As of 2006, there were an estimated 675 lions in the Tsavo national parks, out of the 2,000 total in Kenya. Between 2004 and 2013, lion guardians around Amboseli National Park identified 65 lions in an area of 3,684 km2 (1,422 sq mi). Lion populations in Kenya and Tanzania are fragmented over 17 patches ranging in size from 86 to 127,515 km2 (33 to 49,234 sq mi).

Rwanda and Tanzania due to killing of lions during the Rwandan Civil War and ensuing refugee crisis in the 1990s. A small population was present in Rwanda's Akagera National Park, estimated at 35 individuals at most in 2004. Lions were reintroduced to this national park in 2015.

Malawi and Zambia due to illegal hunting of prey species in protected areas.

Botswana due to intensive hunting and conversion of natural habitats for settlements since the early 19th century. In Northern Tuli Game Reserve, 19 lions died between 2005 and 2011 due to poaching, trophy hunting and snaring.


Namibia due to massive killing of lions by farmers since at least the 1970s. In 2010, the small and isolated lion population in the Kalahari was estimated at 683 to 1,397 individuals in three protected areas, the Kgalagadi Transfrontier Park, the Kalahari Gemsbok and Gemsbok National Parks.
South Africa since the early 19th century in the Natal and Cape Provinces south of the Orange River, where the Cape lion population was eradicated by 1860.

A few decades later, lions in the Highveld north of the Orange River were also eradicated. In Transvaal, lions occurred historically in the Highveld as well, but were restricted to eastern Transvaal's Bushveld by the 1970s. Between 2000 and 2004, 34 lions were reintroduced to eight protected areas in the Eastern Cape Province, including Addo Elephant National Park. In Venetia Limpopo Nature Reserve, 18 lions were trophy hunted and 11 euthanized between 2005 and 2011.

Contemporary lion distribution and habitat quality in East and Southern Africa was assessed in 2005, and Lion Conservation Units (LCU) mapped. Between 2002 and 2012, educated guesses for size of populations in these LCUs ranged from 33,967 to 32,000 individuals. The LCUs Ruaha−Rungwa, Serengeti−Mara, Tsavo−Mkomazi and Selous in East Africa, as well as Luangwa, Kgalagadi, Okavango−Hwange, Mid−Zambezi, Niassa and Greater Limpopo in Southern Africa are currently considered lion strongholds. These LCUs host more than 500 individuals each, and the population trend is stable there as of 2012.


Lions usually hunt in groups and prey foremost on ungulates such as gemsbok (Oryx gazella), Cape buffalo (Syncerus caffer), blue wildebeest (Connochaetes taurinus), giraffe (Giraffa camelopardalis), common eland (Tragelaphus oryx), greater kudu (T. strepsiceros), nyala (T. angasii), roan antelope (Hippotragus equinus), sable antelope (H. niger), plains zebra (Equus quagga), bushpig (Potamochoerus larvatus), common warthog (Phacochoerus africanus), hartebeest (Alcephalus buselaphus), common tsessebe (Damaliscus lunatus), waterbuck (Kobus ellipsiprymnus), kob (K. kob) and Thomson's gazelle (Eudorcas thomsonii). Their prey is usually in the range of 190–550 kg (420–1,210 pounds). In the Serengeti National Park, lions were observed to also scavenge on carrion of animals that were killed by other predators, or died from natural causes. They kept a constant lookout for circling vultures, apparently being aware that vultures indicate a dead animal. Faeces of lions collected near waterholes in Hwange National Park also contained remains of climbing mice (Dendromus) and common mice (Mus).

In Botswana's Chobe National Park, lions also prey on young and subadult African bush elephants (Loxodonta africana). They successfully attacked 74 elephants between 1993 and 1996, of which 26 were older than nine years, and one bull over 15 years old. In October 2005, a pride of up to 30 lions killed eight African bush elephants that were between four and eleven years old.



In the 1890s, two Tsavo Man-Eaters attacked workers during the building of the Uganda Railway. Their skulls and skins are part of the zoological collection of the Field Museum of Natural History. The total number of people killed is unclear, but allegedly 135 people fell victim to these lions in less than a year before Colonel Patterson killed them.

The Njombe lions were a lion pride in Njombe in former Tanganyika, which are thought to have preyed on 1,500 to 2,000 people. They were killed by George Gilman Rushby.

Between 1990 and 2004, lions killed more than 560 people in Tanzania, mostly during harvest season in crop fields and in areas where natural prey is scarce.
In February 2018, lions killed a suspected poacher near Kruger National Park.

In February 2018, Kevin Richardson took three lions for a walk at Dinokeng Game Reserve in South Africa. A lioness pursued an impala for at least 2 km (1.2 mi), and killed a young woman near her car.
In July 2018, human remains were found in the lion enclosure of a privately owned reserve in South Africa. They were suspected to have been rhino poachers, as they had a high-powered rifle with a silencer, an axe and wire cutters.


African lions are included in CITES Appendix II. Today, lion populations are stable only in large protected area complexes. IUCN regional offices and many wildlife conservation organisations cooperated to develop a Lion Conservation Strategy for Eastern and Southern Africa in 2006. The strategy envisages to maintain sufficient habitat, ensure a sufficient wild prey base, make lion-human coexistence sustainable and reduce factors that lead to further fragmentation of populations. Local communities in several Southern African lion range countries generate significant income through wildlife tourism, which is a strong incentive for their support of conservation measures.

Establishing corridors between protected areas is important for facilitating dispersal of lions. Makgadikgadi Pans National Park and Central Kalahari Game Reserve are key dispersal areas in Southern Africa.

27-5-2019 SOMALISA CAMP, ZIMBABWE - SENEGAL COUCAL (Centropus senegalensis)


The Senegal coucal (\(Centropus\) \(senegalensis\)) is a medium-sized bird from the cuckoo family, found across much of sub-Saharan Africa in habitats with dense undergrowth like tall grasslands and savannas. Its plumage is black on the head and upper parts, with a long black tail, and creamy white underparts, though juveniles are browner and barred. These birds are known for their distinctive descending "boop" call, are often heard before they are seen, and have a diet that includes insects, small vertebrates, and eggs. 

Appearance 
Adult: Glossy black head and neck, black wings with a chestnut color, and a long, black tail. The underparts are creamy white, sometimes with reddish reflections on the flanks and abdomen. Red-ringed red eyes give the bird a stern look.

Juvenile: Browner and more heavily barred on the back, wings, and tail.Size: Approximately 39 cm (15 inches) long.

Also consumes scorpions, beetles, ants, small lizards, snakes, and rodents.

27-5-2019 SOMALISA CAMP, ZIMBABWE - CHAPMAN'S ZEBRA (Equus quagga ssp. chapmani)


Chapman's zebra (Equus quagga chapmani), named after explorer James Chapman, is a subspecies of the plains zebra from southern Africa.

Chapman's zebra are native to savannas and similar habitats of north-east South Africa, north to Zimbabwe, west into Botswana, the Caprivi Strip in Namibia, and southern Angola. Like the other subspecies of plains zebra, it is a herbivore that exists largely on a diet of grasses, and undertakes a migration during the wet season to find fresh sources of food and to avoid lions, which are their primary predator. Chapman's zebras are distinguished from other subspecies by subtle variations in their stripes. When compared to other equids in the region Chapman's zebras are relatively abundant in number, however its population is now in decline largely because of human factors such as poaching and farming. Studies and breeding programs have been undertaken with the hope of arresting this decline, with a focus on ensuring zebras bred in captivity are equipped for life in the wild, and that non-domesticated populations are able to freely migrate. A problem faced by some of these programs is that captive Chapman's zebra populations experience higher incidence of diagnosed diseases than non-domesticated populations because they live longer, and so are less likely to die in the wild from predation or a lack of food or water.


Chapman's zebras are single-hoofed mammals that are a part of the odd-toed ungulate order. They differ from other zebras in that their stripes continue past their knees, and that they also have somewhat brown stripes in addition to the black and white stripes that are typically associated with zebras. The pastern is also not completely black on the lower half. Each zebra has its own unique stripe pattern that also includes shadow stripes. When foals are born, they have brown stripes, and in some cases, adults do not develop the black colouration on their hides and keep their brown stripes.


In the wild Chapman's zebra live on average to 25 years of age, however that can live to be up to 38 years of age in captivity. Males usually weigh 270–360 kg (600–800 lb) and stand at 120–130 cm (48–52 in) tall. Females weigh about 230–320 kg (500–700 lb) and stand as tall as the males. Foals weigh 25-50 kg (55-88 lb) at birth. Adult zebras can run at up to 56 kilometres per hour (35 miles per hour) and have strong eyesight and hearing which are essential evolutionary defence mechanisms.

Chapman's zebras have been observed to spend a large portion of their day feeding (approximately 50%), and primarily consume low-quality grasses found in savannas, grasslands, and shrublands, however they occasionally eat wild berries and other plants in order to increase protein intake. While they show a preference for short grasses, unlike some other grazing animals they also eat long grasses and so play an important role by consuming the upper portion of long grass that has grown in the wet season to then allow for other animals to feed. Young foals are reliant on their mothers for sustenance for approximately the first 12 months of their lives as their teeth are unable to properly breakdown the tough grasses that the adults eat until the enamel has sufficiently worn away.


During the dry season Chapman's zebras tend not to stray too far from a water source as they frequently have to drink. During the wet season however, the zebras will join together in large herds consisting of many harems and migrate in order to find abundant food sources to feed on after the relatively sparse dry season They also try to avoid other animal migrations so as to lower competition for food. As they only require lower-quality foraging, Chapman's zebras prefer to migrate to areas with a greater density of food, and will prioritise quantity ahead of quality. By optimising foraging density and avoiding other foraging species, Chapman's zebras are able to sustain large populations which rapidly deplete foraging areas forcing them to continue migrating. In addition, Chapman's zebras also exhibit a cyclical daily movement whereby they prefer grasslands during the day and woodlands during the night so as to avoid lions, which are their main predator.. They frequently move around and actively avoid areas where they recently observed lion activity.


Chapman's zebras are highly sociable animals that live in herds of up to tens of thousands of individuals. The larger herd is composed of harems with permanent members; consisting of one herd stallion, one to six females, and their offspring. They rarely exhibit aggressive behaviour towards each other or other species. Males without a harem have also been observed to form long term cliques of their own with other bachelor males which has been shown to improve their social skills. Stallion-stallion groups are uncommon, and in the cases where they do form they are short-lasting. The females stay in the same harems all of their lives.


Chapman's zebras spend time resting during the day and are more active at dusk. This is most likely a defensive behavioural trait as predators are more prevalent at this time of day, and so it is beneficial for members of the herd to be more vigilant at these times. On occasion a small group will rush at a potential predator in an attempt to deter it from attacking, however in general Chapman's zebras prefer to avoid any such conflicts.


Within their harems there has been observed hierarchical social structures which dictate things such as the movements of the group, through to how they care for their offspring. High-ranking mares in particular exert pressure on the group in order to promote the survival of their own foals. When foraging, Chapman's zebras rely on the dominant member of the harem to lead them to water and food sources. The success of high-ranking harem members at leading the group to food and water determines whether they maintain leadership into the future, and shows how the zebras value stability in their respective groups. Leadership roles can change over time however. Older mares often have a higher social rank than younger harem members. Lactating females are also able to initiate movement within a harem which in turn can sometimes influence the movements of the whole herd. When a pregnant mare gives birth her foal assumes the same social status within the harem as her.


From a young age foals are able to recognise the scent and sound of their mother and form bonds together that last into adulthood. This ability to recognise other zebras does not diminish into adulthood where they are able to differentiate amongst other group members. This is essential for creating stability within groups, which lowers inter-group competition for resources and thus improves survival. In captivity has been shown that Chapman's zebras form unique relationships with different keepers and that they alter their behaviour depending on which keeper is interacting with them.
Males will typically fight one another in front of a group of females before they mate with them, with the highest-ranking mare in the harem the first to mate. The gestation period for Chapman's zebras is around 12 months, after which time the female will give birth to a single foal. The foal is soon able to walk with the rest of the group. This is essential for its survival, as it ensures that the mother does not have to leave it behind for the good of the other members of the harem. Each subsequent pregnancy follows a shorter period between births than the one before it as the mare become more adept at raising her foals. Male zebras that are members of the harem but not the father of the foal have been reported to practise infanticide. This has been observed in particular in captivity where zebras from different social groups are kept in close proximity. It is also possible for Chapman's zebras to be bred via an equine surrogate, as was first done in 1984.
