The inhabitants of South Africa’s wild places

Yellow-billed Duck

Anas undulata

The Yellow-billed Duck is a common and widespread species of dabbling duck, found on or near almost any fresh water habitat, including farm dams, flooded grasslands, slow-flowing rivers and seasonal pans, and sometimes in brackish environments like estuaries. They avoid fast-flowing rivers. These ducks are omnivorous, feeding on terrestrial and aquatic plants, including crops, as well as insects, crustaceans and molluscs. Adults weigh around 1kg.

During the moult (which lasts for about 4 weeks at the end of the summer) or in times of drought they can congregate in flocks of up to 5,000, dispersing again at the onset of the rainy season to then be seen mostly as pairs or in small groups. Yellow-billed Ducks are mostly nocturnal, feeding from dusk to dawn.

Breeding takes place at any time of year, with a peak in summer. Nests are built of plant material lined with down, near to the water and on the ground in dense vegetation. Clutches contain up to twelve eggs. Only the female incubates the eggs and cares for the chicks. The eggs hatch after about a month and the female then leads the ducklings to the water. The ducklings can fly by the time they are two months old.

It is estimated that there are at least 100,000 Yellow-billed Ducks in South Africa, where they commonly occur almost everywhere except in parts of the arid west of the country. The construction of artificial impoundments has certainly benefited this species, aiding an increase both in their range and populations. North of our borders they occur throughout East and Central Africa, and thanks to their wide distribution and large, stable populations are considered of least concern by the IUCN. Hybridization with feral populations of the exotic Mallard is cause for concern however, especially in South Africa.

Red-billed Oxpecker

Buphagus erythrorhynchus

Red-billed Oxpeckers subsists almost entirely on a diet of ticks and their larvae, maggots and other ecto-parasites, picked from the hides and orifices of large mammalian herbivores. They will however also peck at open wounds to feed on the blood. They are therefore closely associated with savannas and woodlands inhabited by good numbers of these large host animals, associating especially with the hairier game species like giraffes and antelope, as well as cattle and donkeys. Adults are about 20cm long and weigh around 50g.

At night, Red-billed Oxpeckers sleep in small flocks in trees, being especially fond of lalapalms. These birds nest in holes in trees lined with the fur of wild and domesticated mammals, particularly in the wet summer months. Usually there are three eggs in a clutch, incubated by both parents.

Red-billed Oxpeckers occur from Eritrea southwards to South Africa, where they can be found in the provinces of Kwazulu-Natal, Mpumalanga, Limpopo, Gauteng and Northwest, while an isolated population seems to have become established in the Eastern Cape as well. The eradication of wild game and the dipping of cattle has a detrimental impact on the food supply of the Red-billed Oxpecker, causing their populations outside protected areas to decline and, while the IUCN still views it as being of Least Concern, they are considered Near Threatened in South Africa and regularly reintroduced to reserves in areas from which they were previously exterminated.

Southern Masked Weaver

Ploceus velatus

The Southern Masked Weaver is a common inhabitant of savannas, woodlands, grasslands, riverine thickets in arid areas, and suburban gardens, feeding on insects, nectar and seeds.

The breeding season stretches through spring and summer, when the males don their brilliant black-and-yellow plumage and try to breed with as many females as possible, attracting them with neat nests weaved of grass or palm throngs on thin twigs or reeds (or wires and fences), usually hanging over water. Southern Masked Weavers normally move around singly or in small groups, but breed colonially. Only the female incubates the clutch and rears the chicks.

The IUCN considers the Southern Masked Weaver to be of “least concern” as they are common all over their distribution range, which covers Angola, Zambia, Malawi, Mozambique, Botswana, Namibia and all of South Africa, Lesotho and Swaziland.

Black-backed Jackal

Canis mesomelas

Considered a cunning creature of tricks and magic in local folklore and reviled by small stock farmers, Black-backed Jackals are the most common canid occurring in South Africa. Easily recognisable by their black-and-silver “saddles”, these jackals stand between 30 and 48cm high at the shoulder and weigh between 5 and 13kg.

Black-backed Jackals have a very wide habitat tolerance, and can be found from desert coasts to high mountain ranges, though they prefer drier, more open country and avoid forested areas. They are even known to live in the suburbs of many towns and cities. They are equally catholic in their diet and there’s very little that a Black-backed Jackal will not eat. Where they share their range with large predators, like lions, leopards and cheetahs, carrion makes up a large proportion of their intake, though they are quite capable hunters and will prey on anything from invertebrates to fish, reptiles, birds and small mammals up to medium-sized antelope like the springbok and seal pups. They will also eat berries, fruit and rizomes. Black-backed Jackals are independent of drinking water, but will drink when it is available.

Black-backed Jackals are nocturnal animals, usually emerging at dusk and returning to their dens at dawn, though they may at times be active throughout the day, and especially so in overcast weather. By day they sleep in thickets, caves or holes dug in the ground by other animals, The normal social grouping consists of a mated pair with their offspring, often of consecutive litters, defending fairly large territories. Apart from being very clever animals, Black-backed Jackals are quite brave and tenacious, and will even mob lions and hyenas on a carcass.

Black-backed Jackals pairs usually have litters of 3-4 pups born on late winter or spring after a short 2 month gestation. Previous litters help the dominant pair to raise the youngest offspring by bringing food to the den (usually a cave or hole in the ground). Black-backed Jackals often fall prey to larger carnivores (leopards are especially fond of jackal meat), are also very susceptible to mange, distemper and rabies, and have a life expectancy of only 6 to 14 years in the wild.

The IUCN considers the Black-backed Jackal as being of least concern, being common with a stable population over most of its distribution in East and Southern Africa, despite being persecuted as vermin by farmers. They occur all over South Africa, though they are understandably much easier to see in conservation areas than in farming communities. In our experience good places to go looking for Black-backed Jackals are the Kruger National Park (especially around Satara), Addo Elephant, Golden Gate, Marakele and Pilanesberg National Parks, Giant’s Castle in the uKhahlamba Drakensberg Park, and Rietvlei Nature Reserve.

 

Swainson’s Spurfowl

Pternistis swainsonii

Swainson’s Spurfowl is a fairly large (up to 800g) type of francolin. They are normally encountered in pairs or small groups numbering up to 6 in woodland, savanna, grassland and planted fields, where they subsist on seeds, berries, other plant material and insects.

In South Africa, these birds breed mostly in summer and autumn, although nesting has been recorded throughout the year. Nests are well-hidden scrapes in the ground in which up to 7 eggs are laid.

Swainson’s Spurfowl is a common resident of South Africa’s northern provinces (Kwazulu-Natal, Free State, Gauteng, North West, Limpopo and Mpumalanga). Outside of our borders they occur in Lesotho, Swaziland, Angola, Namibia, Botswana, Zimbabwe, Mozambique and Zambia, and marginally into Malawi. Despite being hunted as food, the IUCN considers Swainson’s Spurfowl as being of “Least Concern” owing to an abundant and aparently stable population.

Lilac-breasted Roller

Coracias caudatus

Few people would fail to be impressed by the beautiful plumage of the Lilac-breasted Roller, especially when seeing those electric colours swooping past in flight!

Lilac-breasted Rollers are inhabitants of the more open woodlands and savannas, often perching quite conspicuously on trees or poles, either singly or in pairs. They are mostly insectivorous in diet, though they will also take small reptiles, frogs, small birds and rodents when the opportunity arises. They’re often seen at veldfires, hawking the small prey items trying to escape the flames. They are acrobatic fliers, hence the name.

Pairs are monogamous and strictly territorial. In South Africa, this species breeds mostly in spring, nesting in abandoned holes made by other birds and animals in trees. Clutches contain 2-4 eggs and are incubated by both parents for just over three weeks.

These colourful birds are common residents of Eastern and Southern Africa, and considered of “least concern” by the IUCN. In South Africa they can be found from Northern Kwazulu-Natal through Mpumalanga, Limpopo Province, the North of Gauteng and North-West Province to the Kalahari regions of the Northern Cape.

Northern Black Korhaan

Afrotis afraoides

The Northern Black Korhaan is a species of open grassland, dry savanna and semi-arid scrub. They feed primarily on insects and other invertebrates as well as seeds. Adults can weigh up to a kilogram.

Male Northern Black Korhaans are fiercely protective of their territory and attempt to mate with as many females as possible, whom they attract by an elaborate courtship dance. Females incubate the clutch (1-3 eggs) for about three weeks and then raise the chicks on their own. They don’t construct a nest, instead laying their eggs directly on the ground among tufts of grass, often under small thorn bushes. Most chicks are raised in the spring and summer.

Northern Black Korhaan occur on South Africa’s central Highveld, principally the provinces of the Eastern and Northern Cape, Northwest, Free State, Limpopo, Mpumalanga and Gauteng. Its range also extends into Botswana and Namibia. The IUCN considers the species of “least concern” as it has a stable population and appears to be common throughout its range.

African Stonechat

Saxicola torquatus

African Stonechats generally inhabit higher altitude grasslands with long, rank growth, though in South Africa they also occur down to sea level in suitable habitat, and especially so during the colder winter months. The African Stonechat has also adapted very well to large scale agriculture, though they avoid overgrazed areas. They feed mainly on small insects and other invertebrates. These are active little birds, only 13cm long and weighing only 12 – 17g.

African Stonechats are usually seen in pairs, and breeding occurs in spring and summer. Females build their nests of grass and softer material in the shape of a deep cup, usually positioned on the ground at the base of a bush or other plant providing good cover. Clutches, containing up to 6 eggs, are incubated only be the female for a period of two weeks, but both parents feed the chicks once they’ve hatched. Chicks leave the nest at about two weeks of age, and then stay with their parents for a further three weeks or so.

The African Stonechat is a common sight in South Africa, occurring all over the country with the exception of the arid interior of the Northern Cape Province. They are also patchily distributed over East and Central Africa, and is considered common throughout its range.

Egyptian Goose

Alopochen aegyptiaca

The well-known Egyptian Goose is a large (up to 3.5kg) duck that is probably South Africa’s most numerous waterfowl species.

Egyptian Geese inhabit almost every freshwater habitat, preferring rivers and waterbodies with open shorelines within easy reach of open fields for grazing. Their diet is mostly vegetarian, particularly including grasses and cultivated crops (which is why they are regarded as pests in some parts of their range).

Outside of the breeding season, which in South Africa mainly stretches from late winter to early summer, Egyptian Geese can be found in large flocks of hundreds, even thousands, especially so while moulting (which leaves them flightless for about a month). In the breeding season however pairs are more solitary in habit, viciously defending small territories around their nests and goslings from others of their kind. Nests, lined with plant material, are bult in a variety of places ranging from shallow depressions hidden on the ground in thick vegetation to burrows, the abandoned nests of other large birds, holes in trees, cliffs, caves and buildings. Pair bonds often last for life, and the females incubate the clutch of 5 to 11 eggs for about 4 weeks. Chicks hatched in elevated nests have to jump out after hatching, responding to the call of their mother below, and then follow the parents to water. Both parents take care of the young, which start flying at around 10 weeks of age.

The IUCN considers the Egyptian Goose as being of “Least Concern“, having a large (though likely decreasing) population distributed over most of Sub-Saharan Africa, with introduced or feral populations in many other parts of the world. Ironically they no longer occur on the lower Nile, where they were once considered sacred by the ancient Egyptians. They are however a very familiar sight all over South Africa.

Common Hippopotamus

Hippopotamus amphibius

Although the Hippopotamus seldom needs any introduction, most people are entirely unaware of just how big these portly animals are. Bulls can reach 1.7m high at the shoulder and weigh as much as 3,200kg (though usually around 2 tons), while cows are smaller, reaching weights of 1,700kg.

Hippopotamus require deep, permanent pools in slow-flowing rivers, dams and lakes, usually with exposed banks and islands and easy access to grazing grounds. They consume 100kg or more of fodder daily, consisting mostly of grass but will also feed on fruits, reeds and other waterplants. Areas subject to heavy grazing by Hippo take on a park-like appearance, with short “mown” lawns. They have been recorded taking carrion from carcasses. In times of drought hippos will travel up to 30km in a night to reach grazing, and will try to make do with any water or mudhole as protection from the sun.

Hippos live in herds consisting of a territorial bull, cows and calves, numbering from 2 to 200 (usually around 15). The territorial bull will tolerate other mature bulls in his area provided they act suitably submissively – if not, terrible fights will break out in which one or both combatants are often killed. Inside the group the cows also maintain a strict hierarchy. Territories are demarcated by dungpiles and scattering droppings on prominent bushes and rocks by flicking the tail. Hippos follow specific trails between their waterhole and feeding grounds, and is especially dangerous when encountered along these. In fact, Hippos are among the most dangerous of African animals and cause several human deaths annually. Instances have also been noted of Hippos killing (by drowning or biting) other herbivores or crocodiles which venture too close. They are surprisingly fast on land, capable of speeds in excess of 35km/h, and are just as fast in the water. Hippos are most active at night, preferring to spend the hot daylight hours lolling in the water or baking in the sun on a sandbank and then heading out to feed at dusk.

Most Hippo calves are born in the rainy season, when cows give birth to a single offspring after a gestation of about 8 months. The calves are usually born in reedbeds, where they remain hidden for a few weeks before being introduced to the herd as bulls are known to kill calves, even their own. Cows are incredibly protective of their young and nursing usually takes place in the water. Thanks to their large size and aggressive nature, few Hippos succumb to predator attacks, though lions, hyenas and crocodiles will attempt to catch calves given an opportunity. Drought and starvation are the biggest cause of natural deaths in Hippo populations. They have a life expectancy of up to 50 years in the wild.

Owing to a declining population due to poaching and loss of habitat, the IUCN considers the Hippopotamus to be “Vulnerable” and estimate that the total African population numbers between 125,000 and 148,000. It is estimated that there are at least 5,000 (and probably considerably more) Hippos in South Africa, where they now occur naturally only in the Lowveld of the Mpumalanga and Limpopo Provinces and the north of Kwazulu-Natal, although reintroductions have occurred outside these areas. Reliable places to see Hippos in South Africa are the Kruger National Park, iSimangaliso Wetland Park and Pilanesberg National Park.
