3-6-2019 LINYANTI CAMP, BOTSWANA - COMMON WATERBUCK (Kobus ellipsiprymnus ssp. ellipsiprymnus)
%2020.jpg)
The waterbuck (Kobus ellipsiprymnus) is a large antelope found widely in sub-Saharan Africa. It is 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. 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.
Waterbucks are rather sedentary in nature. As gregarious animals, they may form herds consisting of six to thirty individuals. These groups are either nursery herds with females and their offspring or bachelor herds. Males start showing territorial behaviour from the age of five years, but are most dominant from six to nine. The waterbuck cannot tolerate dehydration in hot weather, and thus inhabits areas close to sources of water. Predominantly a grazer, the waterbuck is mostly found on grassland. In equatorial regions, breeding takes place throughout the year, but births are at their peak in the rainy season. The gestational period lasts 7–8 months, followed by the birth of a single calf.
Waterbucks inhabit scrub and savanna areas along rivers, lakes, and valleys. Due to their requirement for grasslands and water, waterbucks have a sparse ecotone distribution. The IUCN lists the waterbuck as being of least concern. More specifically, the common waterbuck is listed as of least concern, while the defassa waterbuck is near threatened. The population trend for both is downwards, especially that of the defassa, with large populations being eliminated from certain habitats because of poaching and human disturbance.
3-6-2019 LINYANTI CAMP, BOTSWANA - AFRICAN SAVANNA ELEPHANT (Loxodonta Africana)
The African bush elephant (Loxodonta africana), also known as the African savanna elephant, is a species of elephant native to sub-Saharan Africa. It is one of three extant elephant species and, along with the African forest elephant, one of two extant species of African elephant. It is the largest living terrestrial animal, with fully grown bulls reaching an average shoulder height of 3.04–3.36 metres (10.0–11.0 ft) and a body mass of 5.2–6.9 tonnes (5.7–7.6 short tons); the largest recorded specimen had a shoulder height of 3.96 metres (13.0 ft) and an estimated body mass of 10.4 tonnes (11.5 short tons). The African bush elephant is characterised by its long prehensile trunk with two finger-like processes; a convex back; large ears which help reduce body heat; and sturdy tusks that are noticeably curved. The skin is grey with scanty hairs, and bending cracks which support thermoregulation by retaining water.
3-6-2019 LINYANTI CAMP, BOTSWANA - HELMETED GUINEA FOWL (Numida meleagris)
The Helmeted Guineafowl, Numida meleagris, is a distinctive bird, easily recognized by its round body, small head, and striking plumage. Adults typically measure 53 to 58 cm in length and weigh around 1.3 kg. Their feathers are predominantly gray-black, speckled with white, providing them with a somewhat polka-dotted appearance.
One can identify the Helmeted Guineafowl by its bare head adorned with a bony knob, which can be dull yellow or reddish, and the surrounding skin may exhibit red, blue, or black colors. The wings and tail are short, contributing to a rather compact silhouette. Subspecies vary mainly in the size, shape, and color of the casque and facial wattles.
These birds favor warm, open environments with scattered shrubs and trees, such as savannas or farmlands, where they can forage and breed.
Native to Africa, mainly south of the Sahara, the Helmeted Guineafowl has been introduced to various regions worldwide, including the West Indies, North America, Colombia, Brazil, Australia, and Europe.
Helmeted Guineafowls are social creatures, forming flocks of about 25 individuals outside the breeding season. They are ground-dwelling birds, preferring to run rather than fly when threatened. Their flight is short and explosive, relying on gliding for longer distances. They are adept at running and can cover up to 10 km in a day. When alarmed, they emit loud, harsh calls.
3-6-2019 LINYANTI CAMP, BOTSWANA - GUINEAFOWL BUTTERFLY (Hamanumida daedalus)
%2020-topaz-upscale-1.4x.jpg)
The genus Hamanumida comprises of a single species – daedalus, which is popularly known as the Guineafowl due to its colour and pattern which resembles that of the guineafowl bird.
Hamanumida daedalus is widespread across Africa including Madagascar. It also occurs in the Arab states.
This is a grassland / savannah species found at altitudes between sea level and about 800m. It is associated mainly with dry, rocky grassland where there are scattered bushes and trees, but also rapidly colonises abandoned agricultural land.
The primary larval foodplant is Combretum, but Terminalia and Tectona (teak) are also used.
The butterflies are normally seen singly or in two’s and three’s. Males will mud-puddle at the edges of fords and small streams, but both sexes are more commonly seen aggregating at the top of hills where courtship and copulation take place. They fly very low over the ground, and frequently settle to bask on bare ground or on rocks or boulders. At all times they remain very alert, taking flight at the slightest disturbance.
3-6-2019 LINYANTI CAMP, BOTSWANA - GREATER BLUE EARED STARLING (Lamprotornis chalybaeus)
The greater blue-eared starling, or Lamprotornis chalybaeus, is a striking bird adorned in glossy blue-green plumage with a purple-blue belly and a distinctive blue ear patch. This bird measures approximately 22 cm in length and sports a short tail. The iris of this species is a vivid yellow or orange, adding to its captivating appearance. Both sexes exhibit similar coloration, though juveniles can be distinguished by their duller feathers and blackish-brown underparts.
When identifying the greater blue-eared starling, look for its glossy blue-green upperparts and purple-blue belly. The blue ear patch is a key feature, along with its bright yellow or orange iris. Juveniles are less lustrous and have darker underparts. This species can be confused with the lesser blue-eared starling, but the latter's blue belly does not extend forward of the legs.
The greater blue-eared starling is commonly found in open woodland environments, where it thrives and breeds.
This bird has a broad range across the African continent, from Senegal in the west, stretching east to Ethiopia, and then southward through eastern Africa to northeastern South Africa and Angola. It is known to undertake seasonal migrations within this range.
The greater blue-eared starling is a highly social bird, often seen in large flocks that may include other starling species. It is also known to roost communally in reedbeds, thorn bushes, or acacia trees, sometimes sharing these spaces with other birds.
The vocal repertoire of the greater blue-eared starling includes a variety of musical and grating calls. A commonly heard call is a nasal "squee-ar," which is quite distinctive.
Breeding pairs of greater blue-eared starlings make their nests in tree holes, which can be naturally occurring or previously excavated by woodpeckers or barbets. They are also known to utilize the large stick nests of the sacred ibis or Abdim's stork. Their nests typically contain three to five greenish-blue eggs adorned with brown or purple spots. These eggs hatch after about 13–14 days, and the fledglings leave the nest approximately 23 days post-hatching. The species is occasionally parasitized by the great spotted cuckoo and, less frequently, by the greater honeyguide.
An omnivorous bird, the greater blue-eared starling's diet is predominantly insectivorous, foraging mainly on the ground for a variety of invertebrates. It also consumes seeds and berries, with a particular fondness for figs. Additionally, these starlings are known to perch on livestock, picking off insects disturbed by the animals and sometimes removing ectoparasites.
The IUCN Red List classifies the greater blue-eared starling as Least Concern, indicating that the species does not currently face any significant threats to its survival.
3-6-2019 LINYANTI CAMP, BOTSWANA - EMERALD SPOTTED WOOD DOVE (Turtur chalcospilos ssp. zambesiensis)
%2020.jpg)
The emerald-spotted wood dove or emerald-spotted dove (Turtur chalcospilos) is a bird of the family Columbidae, resident across eastern and southern Africa. It is a species of open drier deciduous woodland and second growth. It is absent from evergreen rainforests and semidesert areas.
At Hluhluwe-Umfolozi, South Africa, showing the bluish-emerald wing spots
Calling in woodland during autumn
The emerald-spotted wood dove is a small plump pigeon, typically 20 cm in length. Its back, hindneck, wings, and tail are pale grey-brown, and the folded wings have green metallic patches. There are blackish bands on the lower back and tail. The forehead, crown, and nape are bluish-grey, fading to pinkish-grey on the throat. The underparts are mauve-pink, becoming whiter on the belly.
The bill of this dove is blackish with a red base. The sexes are similar, but the female may be slightly duller than the male. The immature has duller green spots and buff fringes to the feathers. When flying, the black-billed wood dove is told from this species by its bright chestnut underwings.
%2021.jpg)
The call is in three parts: two soft long coos, followed by a series of slow descending coos lasting 10 seconds, and concluding with 4 seconds of rapid coos, which decrease in volume.
This species shows some geographical variation in plumage, but differences are clinal, and emerald-spotted wood dove is now considered to be monotypic.
The emerald-spotted wood dove builds a flimsy stick nest in a tree or shrub, and lays two cream-coloured eggs. Both sexes incubate for 13–17 days to hatching, and feed the squabs for 13–17 days to fledging. Many young birds are taken by mongooses and shrikes.
The emerald-spotted wood dove is not gregarious, but flocks may form at waterholes. This species usually forages on the ground for grass and other small seeds.
3-6-2019 LINYANTI CAMP, BOTSWANA - DICKINSON'S KESTREL (Falco dickinsonii)
%2020.jpg)
Dickinson's kestrel (Falco dickinsoni) is a bird of prey of southern and eastern Africa belonging to the falcon family Falconidae. It is named after John Dickinson, an English physician and missionary who collected the type specimen. It is also known as the white-rumped kestrel. Its closest relatives are the grey kestrel and banded kestrel and the three are sometimes placed in the subgenus Dissodectes.
It is a fairly small, stocky kestrel with a large, square head. It is 27–30 cm (11–12 in) long with a wingspan of 61–68 cm (24–27 in) and a weight of 167–246 g (5.9–8.7 oz). The female is about 4% larger and 10-20% heavier than the male. The plumage is mostly dark grey with a pale head and rump. The tail is grey with narrow black bars and a broad subterminal band. The underside of the flight feathers are also barred. The cere and feet are yellow and there is bare yellow skin around the eye. The bill is dark grey and the eyes are brown. Juvenile birds are grey-brown with barred flanks and without the paler head and rump. They have a greenish cere and eye-ring.
%2021.jpg)
It is usually silent but has a high-pitched alarm and contact call. At the nest, a soft, mewing call attracts the young for feeding.
It inhabits savanna and open woodland, particularly swampy areas near water. It favours miombo woodland[2] and is typically associated with palm trees (such as Hyphaene and Borassus species) and is also often found near baobab trees. It occurs in coconut plantations in some areas.
Its range covers most of Mozambique, Zimbabwe, Zambia and Malawi along with north-eastern South Africa (mainly in Kruger National Park), northern Botswana, north-east Namibia, eastern Angola, southern Democratic Republic of the Congo and parts of Tanzania. It is an occasional visitor to Kenya. The total range is about 3,400,000 km2 (1,300,000 sq mi). It is generally rather scarce but is commoner in some areas such as Zanzibar and Pemba Islands. Loss of palm trees is a potential threat to the species.
%2022.jpg)
It usually hunts from a perch and only occasionally hovers. Large insects such as grasshoppers form the bulk of the diet. It also feeds on lizards and amphibians and sometimes birds, bats, rodents and snakes. It is often attracted to grass fires where it preys on fleeing insects and other prey.
The breeding season lasts from July to October in Tanzania and September to December further south. The nest is a simple scrape with no material used. It is sited 2 to 18 m (6.6 to 59.1 ft) above the ground in the crown of a dead palm or in a hole in a baobab. Sometimes the old nest of a Hamerkop is used. One to four eggs are laid. They are cream-coloured with reddish-brown markings and are incubated by the female for at least 30 days. The young birds fledge after approximately 33 to 35 days.
3-6-2019 LINYANTI CAMP, BOTSWANA - BRADFIELD'S HORNBILL (Lophoceros bradfieldi)
%2020.jpg)
Bradfield's hornbills are African birds found in southern Africa's woodlands, characterized by a black back, white belly, and an orange beak. They are medium-sized, live solitarily or in pairs, and primarily eat fruits, insects, and small reptiles. A key identification feature is the small white corners on the tail, which are visible in flight.
Identification Appearance: Black back and wings with a white belly and a red-orange beak. The tail has small white corners that are conspicuous in flight. They have a black eye mask.Size: Medium-sized, about \(50-57\) cm (\(20-22\) in) long.Females: Smaller than males and have turquoise facial skin.Call: A long, insistent series of piping notes.
%2021.jpg)
Habitat and diet Habitat: Woodland areas, especially those with mopane and Zambezi teak trees, in northeastern Namibia, northern Botswana, southern Angola, and eastern Zimbabwe.
Diet: Primarily feed on fruits, large insects like locusts and beetles, nuts, and small reptiles. They also hunt for flying insects.
Reproduction Nesting: Typically nest in natural tree cavities.Clutch size: Usually lay 3 eggs.Incubation: The female incubates the eggs alone for about 4 weeks.Parental care: After the chicks hatch, the female leaves the nest to help the male with hunting. The chicks stay in the nest for about 2 months.
Conservation status Status: Classified as "Least Concern" by the IUCN. However, the population is likely declining due to habitat loss from logging.
3-6-2019 LINYANTI CAMP, BOTSWANA - BATELEUR EAGLE (JUVENILE)(Terathopius ecaudatus
The bateleur eagle is a medium-sized eagle native to Sub-Saharan Africa with a distinctive appearance, including a red face and legs, a short tail, and a colorful black and chestnut plumage. Known for its unique, wobbly flight style, this raptor hunts a varied diet of small mammals, birds, reptiles, and carrion, often soaring for long distances to find prey. They pair for life, nest in trees, and are currently listed as endangered due to population decline.
Appearance
Plumage: Adults have a black body, chestnut mantle, rump, and tail, with gray shoulders and wing patches.
Facial features: They have a bright red face and bright red legs.
Size: They measure 55–70 cm (22–28 inches) in length with a wingspan of 168–190 cm (5.5–6.3 feet).
Juveniles: Young eagles are mostly brown with some white dappling.
Behavior and lifestyle
Flight: Their flight is characterized by a rocking or wobbly motion, giving them the name "Bateleur," which means "tightrope walker" or "street performer" in French. They are highly aerial and spend many hours soaring.
Social structure: They are monogamous and typically live and hunt in pairs, although they are territorial.
Mood indicators: The red skin on their face and feet can change color; it flushes bright red when they are excited.
Sunbathing: After bathing, they often stand upright with their wings spread to sunbathe in a classic "phoenix" pose.
Communication: They are generally silent but can produce barks and screams.
Diet
Varied diet: Their diet is not limited to snakes and includes small mammals, birds, reptiles, and carrion.
Hunting: They hunt by soaring over a large territory, sometimes covering up to 250 square miles.
Reproduction
Nesting: They build sturdy stick nests in large trees.
Eggs: They lay only one egg at a time.
Life cycle: Incubation lasts about 50-60 days, and the young fledge after about 100 days.
Conservation status
Status: The bateleur eagle is listed as endangered.
Threats: Their population is declining, partly due to the use of poison baits, and they are increasingly confined to protected areas.
3-6-2019 LINYANTI CAMP, BOTSWANA - AFRICAN SAVANNA ELEPHANT (Loxodonta Africana)
The African bush elephant (Loxodonta africana), also known as the African savanna elephant, is a species of elephant native to sub-Saharan Africa. It is one of three extant elephant species and, along with the African forest elephant, one of two extant species of African elephant. It is the largest living terrestrial animal, with fully grown bulls reaching an average shoulder height of 3.04–3.36 metres (10.0–11.0 ft) and a body mass of 5.2–6.9 tonnes (5.7–7.6 short tons); the largest recorded specimen had a shoulder height of 3.96 metres (13.0 ft) and an estimated body mass of 10.4 tonnes (11.5 short tons). The African bush elephant is characterised by its long prehensile trunk with two finger-like processes; a convex back; large ears which help reduce body heat; and sturdy tusks that are noticeably curved. The skin is grey with scanty hairs, and bending cracks which support thermoregulation by retaining water.
The African bush elephant inhabits a variety of habitats such as forests, grasslands, woodlands, wetlands and agricultural land. It is a mixed herbivore feeding mostly on grasses, creepers, herbs, leaves, and bark. The average adult consumes about 150 kg (330 lb) of vegetation and 230 L (51 imp gal; 61 US gal) of water each day. A social animal, the African bush elephant often travels in herds composed of cows and their offspring. Adult bulls usually live alone or in small bachelor groups. During the mating season, males go through a process called musth, a period of high testosterone levels and heightened aggression. For females, the menstrual cycle lasts three to four months, and gestation around 22 months, the longest of any mammal.
Since 2021, the African bush elephant has been listed as Endangered on the IUCN Red List. It is threatened foremost by habitat destruction, and in parts of its range also by poaching for meat and ivory. Between 2003 and 2015, the illegal killing of 14,606 African bush elephants was reported by rangers across 29 range countries. Chad is a major transit country for smuggling of ivory in West Africa. This trend was curtailed by raising penalties for poaching and improving law enforcement. Poaching of the elephant has dated back to the 1970s and 80s, which were considered the largest killings in history. In human culture, elephants have been extensively featured in literature, folklore and media, and are most valued for their large tusks in many places.

2-6-2019 LINYANTI CAMP, BOTSWANA - VERREAUX'S EAGLE OWL (Bubo lacteus)
Verreaux's eagle-owl (Ketupa lactea), also commonly known as the milky eagle owl or giant eagle owl, is a member of the family Strigidae. This species is widespread in sub-Saharan Africa. A member of the genus Ketupa, it is the largest African owl, measuring up to 66 cm (26 in) in total length. This eagle-owl is a resident primarily of dry, wooded savanna. Verreaux's eagle-owl is mainly grey in color and is distinguishable from other large owls by its bright pink eyelids, a feature shared with no other owl species in the world.
Verreaux's eagle-owl is a highly opportunistic predator equipped with powerful talons. Just over half of its known diet is composed of mammals but equal or even greater numbers of birds and even insects may be hunted locally, along with any other appropriately sized prey that is encountered. This species is considered of Least Concern by IUCN as it occurs over a wide range and has shown some adaptability to human-based alterations and destruction of habitat and adaptability to diverse prey when a primary prey species declines in a region. As a large, highly territorial species of owl, it does, however, occur at fairly low densities and some regional declines have been reported.
The common name commemorates the French naturalist Jules Verreaux. The type specimen that was later described by Temminck at the Rijksmuseum van Natuurlijke Historie was collected by Verreaux while he was still in his teens.
Verreaux's eagle-owl is found through most of sub-Saharan Africa, though it is absent from most of the deep rainforests. The species is found at the highest densities in eastern and southern Africa. As this species avoids primary forests, it is found very spottily in west Africa. Their western distribution includes The Gambia, Senegal, Guinea and Sierra Leone.
Eastward from those countries to the Central African Republic, the species is distributed in a narrow transitional zone between the Sahara and rainforests. Seemingly isolated populations occur in central Nigeria and central Mali. In south-western Africa, they range up to as far north as the southern parts of the Republic of the Congo and the Democratic Republic of the Congo, through most of Namibia (excluding the coastal regions) and northern South Africa. In east Africa, their distribution is more or less continuous from southern Sudan, Eritrea and inland Somalia down to South Africa as far as the region of the city of Durban.
This species inhabits mainly savanna with scattered trees and thorny vegetation. Verreaux's eagle-owls mainly inhabit rather dry regions, some bordering semi-arid areas. In central Mali, for example, near the extreme northwestern limit of the species range, the habitat that hosts these owls averages less than 55 cm (22 in) of rainfall annually. They also range into riverine forest adjacent to savanna and small, semi-open woodland surrounded by open country, though they are less likely to inhabit heavily wooded habitats. South African eagle-owls are not infrequently found around floodplains and marshes, which may provide the primary nesting habitat in some areas. In Uganda, they are largely associated with riparian woodlands. Verreaux's eagle-owl may live at nearly all elevations, from sea level to near the snow-line at around 3,000 m (9,800 ft) in elevation, such as in the Eastern Rift mountains. However, in general, they only sporadically inhabit rocky areas and so are generally very scarce in mountainous regions. The bushveld of southern Africa is near ideal habitat for Verreaux's eagle-owl and the species may be found at near peak numbers here. The species was historically rare to absent from the Kalahari Desert, but the introduction by man of invasive trees like conifers, eucalyptus and acacias, irrigation areas and prey species has allowed them to spottily occupy this region.
2-6-2019 LINYANTI CAMP, BOTSWANA - BROWN SNAKE EAGLE (Circaetus cinereus)
%2020.jpg)
The brown snake-eagle is a large African bird of prey that specializes in hunting snakes, including venomous species like cobras and puff adders, which it kills by crushing their spine with its powerful feet. This solitary bird is found in sub-Saharan Africa in open woodlands and savannas. It has thick-scaled legs for protection against bites, hunts from an exposed perch, and typically lays only one egg per breeding season.
Diet and hunting
Primary prey: The brown snake-eagle's diet consists mainly of snakes, both venomous and non-venomous, such as cobras, puff adders, and mambas. It will also eat other prey like lizards, monitor lizards, and small mammals.
Hunting technique: It hunts by perching on a high, exposed spot and scanning the ground below for prey. When it spots prey, it will swoop down to strike, using its powerful feet and talons to crush the snake's spine before it can bite.
%2021.jpg)
Venom defense: It has heavily scaled legs that provide some protection against snake bites, but it is not immune and can sometimes be killed by its prey.
Physical characteristics
Appearance: It is a large bird with a uniform brown head and body, yellow eyes, and a black beak. Its tail has narrow white barring.
Size:
Length: 68-75 cm
Wingspan: 1.6-1.75 m
Weight: Around 2 kg
Habitat and distribution
Range: Found throughout sub-Saharan Africa.
%2022.jpg)
Habitat: Prefers open, dense woodlands, savannas, and areas with low hills or gulleys. It avoids lowland forests and deserts.
Status: Listed as "least concern" by the IUCN due to its large range, even though it is not very common in most areas.
Breeding and life cycle
Solitary nature: The brown snake-eagle is a solitary bird, though they may perch in pairs.
Nesting: It builds a small platform nest of sticks, sometimes reusing old nests from other birds.
Reproduction: Lays a single egg and incubates it for about 50 days. Both parents feed the chick, and the young bird fledges around 95-113 days old.
2-6-2019 LINYANTI CAMP, BOTSWANA - ZAMBESI CRESTED BARBET (Trachyphonus vaillantii ssp. nobilis)
The crested barbet, Trachyphonus vaillantii, is a small, vibrantly colored bird, easily recognized by its thick bill and speckled plumage. Its face is a mosaic of yellow and red, adorned with a modest black crest. The belly mirrors the face with yellow and red speckles, while the wings are black with white dots. A striking black band encircles its neck. The bird's overall yellow hue, peppered with black and white feathers and red at the body's end, provides excellent camouflage in its natural bush habitat. The crested barbet's call is a distinctive trill.
When identifying the crested barbet, look for its unique coloration and markings. The combination of a yellow and red speckled face, a small black crest, and a broad black neck band are key features. The bird's trilling call can also serve as an auditory clue to its presence.
The crested barbet thrives in a variety of environments, including forests, savannahs, suburban gardens, woodland thickets, and areas near watercourses.
This species is widely distributed across sub-Saharan Africa, with sightings confirmed in Angola, Botswana, Burundi, the Democratic Republic of the Congo, Eswatini, Malawi, Mozambique, Namibia, Rwanda, South Africa, Tanzania, Uganda, Zambia, and Zimbabwe.
Crested barbets are typically observed alone or in pairs. They exhibit a preference for foraging on the ground but are also known to vocalize from exposed branches. Their flight is limited and typically consists of short bursts. These birds roost in tree cavities and are highly territorial, often aggressively defending their space against other birds and even larger threats like rats and snakes.
The male crested barbet is renowned for its continuous trill, a call that can persist for extended durations, serving as a vocal beacon within its habitat.
%2020.jpg)
Crested barbets are monogamous and territorial during the breeding season. They nest in tree holes or logs, with territory size varying by habitat. Their breeding season spans from September to December, during which they may lay one to five eggs at daily intervals. Incubation, primarily by the female, lasts between 13 and 17 days starting from the second or third egg. The hatchlings are altricial, being naked and blind at birth, and are fed insects by both parents. After about 31 days, the fledglings leave the nest, and up to five broods may be raised in a single season.
The crested barbet's diet is omnivorous, consisting of insects, other birds' eggs, fruits, and occasionally small mammals like mice.
The IUCN Red List classifies the crested barbet as Least Concern, indicating that the species does not currently face any significant threats to its survival.
2-6-2019 LINYANTI CAMP, BOTSWANA - COMMON IMPALA (MALE) (Aepyceros melampus ssp. melampus)
The impala (Aepyceros melampus) is a medium-sized antelope that is found in Africa. It was first described to European audiences by German zoologist Hinrich Lichtenstein in 1812. Active mainly during the day, the impala may be gregarious or territorial depending upon the climate and geography. The impala is known for two characteristic leaps that constitute an anti-predator strategy.
Impala is an elegant and magnificent species of antelope. The animal has slender body with the identifying "M"-like marking on the rear. This medium-sized antelope possesses thin, pointed horns with tips, lying far apart from each other. Males of this species are identified by the characteristic "S"-like horns. The elegant limbs of these animals have scent glands behind the ankles. The overall coloration of their fur is red-brown with paler sides. In addition, they have black and white colored areas on their body. Thus, the tail, belly, chin, lips, inside ears as well as the lines above the eyes are colored with white. Meanwhile, black bands cover their thighs, tail, forehead and ear tips.
Impalas are distributed throughout the northeastern part of South Africa, Angola, southern Rwanda, Uganda, and Kenya. Close proximity to a water source is an important life condition for these animals. Generally, they prefer woodland with little undergrowth as well as low to medium-height grassland.
Impalas have polygynous mating system, where each male mates with a number of females. The period of peak breeding activity is March-May. During this period, pregnant females live in isolation to give birth. The gestation period lasts from 194 to 200 days, yielding a single calf, which weighs about 5kgs (11 lbs). After a few days, the calf and the female rejoin the herd. Then, after a while, the calf joins a crèche of other young impalas. They are weaned at 4-5 months old. Male impalas reach reproductive maturity at 1 year of age, while females are ready to breed when they are between 1 and 2 years old. Becoming reproductively mature, they, however, do not rush to establish territories. They typically start mating only at 4 years old.
The animals presently suffer from the fragmentation of their range due to the development of human settlements. In addition, roads such as the Serengeti Highway in Tanzania have an extremely negative effect, making it difficult for scattered migrating populations to move between parks, where the antelopes feed, mate and give birth. In addition, populations in South Africa are exposed to hunting for their meat by local people.
