Its gregarious nature, variety in diet, positive population trend, defence against ticks and symbiotic relationship with the tick-feeding oxpeckers could have played a role in preventing major changes in morphology and behaviour. They are adapted to graze on the lower shorter shoots which are left by other larger antelopes. Huge. Males grow slender, lyre-shaped horns 45–92 centimetres (18–36 in) long. One widely familiar gazelle is the African species Thomson's gazelle (Eudorcas thomsoni), which is around 60 to 80 cm (24 to 31 in) in height at the shoulder and is coloured brown and white with a distinguishing black stripe. That’s why an impala is an antelope, but not a gazelle. However, the Pronghorn antelope … [43] 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. [17], The impala is an important prey species for several carnivores, such as cheetahs, leopards and lions. 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. [17], The impala inhabits woodlands due to its preference for shade; it can also occur on the interface (ecotone) between woodlands and savannahs. During an African safari, often walking in the savannah... or better (and safer), drive through the savannah, we see beautiful animals but sometimes we can’t differentiate them. Gazelles can often be seen on the open plains of southern Serengeti. [42], Impala feed on soft and nutritious grasses such as Digitaria macroblephara; tough, tall grasses, such as Heteropogon contortus and Themeda triandra, are typically avoided. This antelope species is primarily active during the day when it grazes on fruits and other vegetation with one of three types of herds: bachelor, female, or territorial male. Browsers as well as grazers, impala feed on monocots, dicots, forbs, fruits and acacia pods (whenever available). [17] The horns, strongly ridged and divergent, are circular in section and hollow at the base. [13] The impala has scent glands covered by a black tuft of hair on the hindlegs. To confuse you more, the basic answer is: Not all Antelopes are Gazelles, but all Gazelles are Antelopes. [31], Impala are symbiotically related to oxpeckers,[34] which feed on ticks from those parts of the antelope's body which the animal cannot access by itself (such as the ears, neck, eyelids, forehead and underbelly). 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. Their facial glands in front of the eyes produce pheromones those are useful as landmarks. thank you for your question. The weight ranges from 30 to 250 kilograms depending on the species. Rutting males fight over dominance, and the victorious male courts female in oestrus. Unlike Antelopes, most types & both genders of Gazelles have horns. [17] The head-and-body length is around 130 centimetres (51 in). [17] The bulbourethral glands are heavier, testosterone levels are nearly twice as high in territorial males as in bachelors,[46] and the neck of a territorial male tends to be thicker than that of a bachelor during the rut. All rights reserved. Antelopes comprise a wastebasket taxon (miscellaneous group) within the family Bovidae, encompassing those Old World species that are not cattle, sheep, buffalo, bison, or goats; even so, antelope are generally more deer-like than other bovids. [13][24], 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. Four further species are extinct: the red gazelle, the Arabian gazelle, the Queen of Sheba's gazelle, and the Saudi gazelle. Deer are ruminants belong to the Family: Cervidae with about extant 62 species. [4] Its Afrikaans name, rooibok 'red buck', is also sometimes used in English. Sebaceous glands concentrated on the forehead and dispersed on the torso of dominant males[17][20] are most active during the mating season, while those of females are only partially developed and do not undergo seasonal changes. Yes.. with regards to the stotting and the full throttle: it also rhymes! Terms of Use and Privacy Policy: Legal. Active mainly during the day, the impala may be gregarious or territorial depending upon the climate and geography. Since gazelle is a member of the antelope species, their speciality should be understood well. • Diversification is higher among antelopes with the number of species, whereas there are more differences among deer in their size and colour. [13][41] Another study showed that the dicot proportion in the diet is much higher in bachelors and females than in territorial males. Reminds me of my behavior on the road with a nondescript sleeper on the road….slow and lazy until taunted by a playful noisy user. On a Northern Tanzania Safari ( Serengeti, Ngorongoro & Lake Manyara), you are likely to encounter both Antelopes and Gazelles in abundance; it may become clear, however, that they are hard to tell apart. There are many species in Africa and Asia. This is exemplified no better than between the Thompson Gazelle (30kgs) and the huge Eland (950kg).
