The Impala or Rooibok (Aepyceros melampus) is a medium-sized antelope found in eastern and southern Africa. The Impala evolved from an Alcelaphine ancestor. She noted that while this ancestor has diverged at least 18 times into various morphologically different forms, the Impala has continued in its basic form for at least five million years.
The Impala is a medium-sized, slender-bodied antelope, comparable to the Kob, Puku and Grant’s Gazelle in size and build. The head and body length is around 130 centimetres (51 in). Males reach approximately 75–92 cm (30–36 in) at the shoulder, while females are 70–85 cm (28–33 in) tall. Males typically weigh 53–76 kilograms (117–168 lb) and females 40–53 kg (88–117 lb). Sexually dimorphic, females are hornless and smaller than males. Males grow slender, lyre-shaped horns 45–92 cm (18–36 in) long. The horns, strongly ridged and divergent, are circular in section and hollow at the base. Their arch-like structure allows interlocking of horns, which helps a male throw off his opponent during fights; horns also protect the skull from damage.
The glossy coat of the Impala shows two-tone colouration – the reddish brown back and the tan flanks; these are in sharp contrast to the white underbelly. Facial features include white rings around the eyes and a light chin and snout. The ears, 17 cm (6.7 in) long, are tipped with black. Black streaks run from the buttocks to the upper hindlegs. The bushy white tail, 30 cm (12 in) long, features a solid black stripe along the midline. The Impala colouration bears a strong resemblance to the Gerenuk, which has shorter horns and lacks the black thigh stripes of the Impala. The Impala has scent glands covered by a black tuft of hair on the hindlegs. Sebaceous glands concentrated on the forehead and dispersed on the torso of dominant males are most active during the mating season, while those of females are only partially developed and do not undergo seasonal changes. There are four nipples.
The Impala has a special dental arrangement on the front lower jaw similar to the toothcomb seen in strepsirrhine primates, which is used during allogrooming to comb the fur on the head and the neck and remove ectoparasites.
The Impala is diurnal (active mainly during the day), though activity tends to cease during the hot midday hours; they feed and rest at night. Three distinct social groups can be observed – the territorial males, bachelor herds and female herds. The territorial males hold territories where they may form harems of females; territories are demarcated with urine and faeces and defended against juvenile or male intruders. Bachelor herds tend to be small, with less than 30 members. Individuals maintain distances of 2.5–3 m (8.2–9.8 ft) from one another; while young and old males may interact, middle-aged males generally avoid one another except to spar. Female herds vary in size from 6 to 100; herds occupy home ranges of 80–180 ha (200–440 acres; 0.31–0.69 sq mi). The mother–calf bond is weak, and breaks soon after weaning; juveniles leave the herds of their mothers to join other herds. Female herds tend to be loose and have no obvious leadership. Allogrooming is an important means of social interaction in bachelor and female herds; in fact, the Impala appears to be the only ungulate to display self-grooming as well as allogrooming. In allogrooming, females typically groom related Impala, while males associate with unrelated ones. Each partner grooms the other six to twelve times.
Social behaviour is influenced by the climate and geography; as such, the Impala are territorial at certain times of the year and gregarious at other times, and the length of these periods can vary broadly among populations. For instance, populations in southern Africa display territorial behaviour only during the few months of the rut, whereas in eastern African populations, territoriality is relatively minimal despite a protracted mating season. Moreover, territorial males often tolerate bachelors, and may even alternate between bachelorhood and territoriality at different times of the year.
The Impala is an important prey species for Africa’s large carnivore, such as Cheetah, Leopard, Wild Dog, Lion, Hyena, Crocodile and Python. The antelope displays two characteristic leaps – it can jump up to 3 m (9.8 ft), over vegetation and even other Impala, covering distances of up to 10 m (33 ft); the other type of leap involves a series of jumps in which the animal lands on its forelegs, moves its hindlegs mid-air in a kicking fashion, lands on all fours (stotting) and then rebounds. It leaps in either manner in different directions, probably to confuse predators. At times, the Impala may also conceal itself in vegetation to escape the eye of the predator. The most prominent vocalisation is the loud roar, delivered through one to three loud snorts with the mouth closed, followed by two to ten deep grunts with the mouth open and the chin and tail raised; a typical roar can be heard up to 2 km (1.2 mi) away.
Impala browse as well as graze; either may predominate, depending upon the availability of resources. The diet comprises monocots, dicots, forbs, fruits and Acacia pods (whenever available). Impala prefer places close to water sources, and resort to succulent vegetation if water is scarce. An analysis showed that the diet of Impala is composed of 45% monocots, 45% dicots and 10% fruits; the proportion of grasses in the diet increases significantly (to as high as 90%) after the first rains, but declines in the dry season. Browsing predominates in the late wet and dry season, and diets are nutritionally poor in the mid-dry season, when Impala feed mostly on woody dicots.
Impala feed on soft and nutritious grasses such as Digitaria macroblephara; tough, tall grasses, such as Heteropogon contortus and Themeda triandra, are typically avoided. Impala on the periphery of the herds are generally more vigilant against predators than those feeding in the centre; a foraging individual will try to defend the patch it is feeding on by lowering its head. A study revealed that time spent in foraging reaches a maximum of 75.5% of the day in the late dry season, decreases through the rainy season, and is minimal in the early dry season (57.8%).
Males are sexually mature by the time they are a year old, though successful mating generally occurs only after four years. Mature males start establishing territories and try to gain access to females. Females can conceive after they are a year and a half old; oestrus lasts for 24 to 48 hours, and occurs every 12–29 days in non-pregnant females. The annual three-week-long rut (breeding season) begins toward the end of the wet season, typically in May. Gonadal growth and hormone production in males begin a few months before the breeding season, resulting in greater aggressiveness and territoriality. Mating tends to take place between full moons.
Rutting males fight over dominance, often giving out noisy roars and chasing one another; they walk stiffly and display their neck and horns. Males desist from feeding and allogrooming during the rut, probably to devote more time to garnering females in oestrus.; the male checks the female’s urine to ensure that she is in oestrus. On coming across such a female, the excited male begins the courtship by pursuing her, keeping a distance of 3–5 metres (9.8–16.4 ft) from her. The male loses interest in the female after the first copulation, though she is still active and can mate with other males.
Gestation lasts six to seven months. Births generally occur in the midday; the female will isolate herself from the herd when labour pain begins. The perception that females can delay giving birth for an additional month if conditions are harsh may however not be realistic. A single calf is born, and is immediately concealed in cover for the first few weeks of its birth. The fawn then joins a nursery group within its mother’s herd. Calves are suckled for four to six months; young males, forced out of the group, join bachelor herds, while females may stay back.
The Impala inhabits woodlands due to its preference for shade; it can also be found on the interface (ecotone) between woodlands and savannahs. Places near water sources are preferred. In southern Africa, populations tend to be associated with Colophospermum mopane and Acacia woodlands. Habitat choices differ seasonally – Acacia Senegal woodlands are preferred in the wet season, and A. drepanolobium savannahs in the dry season. Another factor that could influence habitat choice is vulnerability to predators; Impala tend to keep away from areas with tall grasses as predators could be concealed there.
Planning carefully is the key to a good Impala taxidermy job. When tanning and oiling the hides, the best chemicals and methods in the world are used to make sure they will last for generations. At Lifeform Taxidermy, we carefully choose our forms to make sure they fit well, and we’ll even custom make the forms according to any instruction, you may have in mind, at no extra cost. Full-mount trophies come with standard natural habitat bases that are made just for them. We use only the best materials and our 40 years of experience in the field to give your trophies new meaning. The finished trophies look life-like. When repair is needed, every effort is made to repair cuts and scrapes while keeping bullet damage to a minimum. Skin preparation and storage tips for a flawless Impala trophy.
Take care of your trophy before you bring it to the taxidermist – field preparation is the most important start. As soon as you take the hit on your trophy, it starts to rot, and the heat of Africa speeds up the decaying process. The hunter must not drag the body of the animal from the site where it was shot to the waiting hunting truck. The trophy should be protected from the hot metal bed of the hunting truck with a thick layer of cut grass or leaves.
So that nothing goes wrong, the skinning needs to start right away. Remove all of the meat, fat, dirt, and blood from the skin. Clean the skin well. After that, allow the skin to drip dry for a short time, it should then be salted. It is recommended to soak the skin in a salt solution for at least five hours and ideally overnight. Use about 20 kg of salt per 100 litres of water. After taking the skin out of the solution, salt it while it is still flat and flesh side up on a clean surface. To get the full effect of the salt, it needs to be absorbed into the skin all over, into all the crevice’s, especially around the facial features. Put the skin in the shade with a layer of salt on it. After 24 hours, dry the cape. Fold with the hair and ears in when it’s dry. To stop insect damage, pesticides must be sprayed on the skin and in the storage area.
Most hunters who ventures onto African territory have Impala on their list of hunts. The Rooibok in Afrikaans, is a common and important antelope species throughout Southern Africa. The young African hunter will often use him as camp meat, Leopard bait, or as a first hunt.
You’ll need to make careful and deliberate stalks if you hunt a Rooibok, as he has excellent hearing and smell as well as vision.
While the .22 centre fire is permitted to use for hunting Impala in most Southern African countries, larger calibres such as the 6mm, 7mm, and even 30 calibres are preferable if you do not want to spend the greater part of the day following a wounded animal. High-quality, heavy-for-calibre round-nose bullets have a stellar reputation for the harsh bushveld environment.
Since this antelope, albeit only medium in size, is surprisingly robust, a high heart/lung shot is your best hope when hunting Impala. High lung shots waste less meat and are more effective for meat hunting. If you want to hit the lungs, aim straight up the front leg about a third of the way, and slightly behind. Any point along the neck is fair game for the neck shot. The brain shot is not for the average sport or meat hunter and should only be tried by the expert hunter.
How you choose an Impala taxidermy mount depends on things like your budget, wall space, and personal taste. When it comes to the creation of a full mount, we find that considerable discussion with the customer yields the best results. This is due to the fact that each form is given a distinct shape and arrangement.
Life-Form Taxidermy will make an exact copy of the skin as soon as they get all of your mounting instructions. All of the skins are tanned and oiled with high-quality products and methods to make sure they are preserved for years. Each skin is put on a manikin to make sure that it fits well. After the eyes and ears are expertly placed, the skin is sewn by a professional. Before making any last changes, the taxidermist waits until the animal is dry. They put the trophies in crates, and the shipping company hired by the client brings them to the client.
Every year, dust the mounts with a soft brush or compressed air to fluff up the hair. Trophies should be protected from common pests by spraying a light mist of normal aerosol surface pesticide around them. Think about preserving your trophy with Mount Medix Africa. This is a product that Life-Form Taxidermy offers.
Keep trophies in a cool, dry place. Daylight makes the mounts fade over time, so artificial light is better. If there’s too much humidity, open the windows or turn on a fan. Due to salt and tan residue, hair can make moisture beads when the humidity is high. Using a tissue that soaks up water will also soak up the salts.
The pricing of any trophy is subject to the costing stipulated per taxidermy order, quantity of trophies and preferred mounting options, along with additional requirements.
Should you wish to receive a quotation prior to the hunt, the taxidermist can generate such for you. Please contact [email protected]
Taxidermy is an art form that involves a complicated step-by-step process to make sure that each trophy looks just right and is of a high enough quality that it will last your whole life.
The time it takes a taxidermist to mount an animal might range from days to weeks, and possibly several months, depending on the quantity of trophies per taxidermy order, the display preferences, and volumes of client trophies to be produced, simultaneously, per production schedule.
This depends largely on the “what, how, when” factors. A taxidermy order also only becomes available for production scheduling upon receipt of the required deposit and trophy mounting instructions.
