Dorcas gazelle

Gazella dorcas

The dorcas gazelle , also known as the ariel gazelle, is a small and common gazelle. The dorcas gazelle stands about 55–65 cm at the shoulder, with a head and body length of 90–110 cm and a weight of 15–20 kg. The numerous subspecies survive on vegetation in grassland, steppe, wadis, mountain desert and in semidesert climates of Africa and Arabia. About 35,000 - 40,000 exist in the wild. The extinct Saudi gazelle from the Arabian Peninsula has been previously considered as a subspecies of the dorcas gazelle.

The dorcas gazelle is similar in appearance to, yet smaller than, the closely related mountain gazelle . Dorcas gazelles have longer ears and more strongly curved horns, which bow outwards then turn inwards and forwards at the tips. Individuals belonging to the Saharan subspecies have very pale, fawn-colored coats. The white underside is bordered with a brown stripe, above which is a sandy stripe. The forehead and face are darker than the body. Subspecies from north of the Sahara tend to be more ochre in color, and have dark flanks and facial stripes. Populations in Israel and around the Red Sea are darker and more reddish.
In the last century, the populations of dorcas gazelle were partially destroyed in all the countries where it was found.

Currently, large populations of dorcas gazelles are found in the Negev and the Arava, with other large populations in Sudan, Iraq, and the southern part of the eastern desert of Egypt. In Israel, only 1000-1500 gazelles remain.


Dorcas gazelles are highly adapted to the desert; they can go their entire lives without drinking, as they can get all of the moisture they need from the plants in their diets, though they do drink when water is available. They are able to withstand high temperatures, but when it is very hot, they are active mainly from dusk to dawn. In areas where they face human predation, they tend to be active only at night to minimise the risk of falling prey to hunters. These gazelles feed on leaves, flowers, and pods of many species of acacia trees, as well as the leaves, twigs and fruits of various bushes. They occasionally stand on their hind legs to browse from trees, and after rain, they have been observed digging out bulbs from the ground. Dorcas gazelles are able to run at speeds up to 80 km/hr to 96 km per hour when threatened, they tail-twitch and make bouncing leaps with their heads held high , possibly to announce they have seen a predator.


When conditions are harsh, dorcas gazelles live in pairs, but when conditions are more favorable, they join together in family herds with one adult male, several females, and young. During the breeding season, adult males tend to be territorial, and mark their range with dung middens. In most parts of their range, mating takes place from September to November. Gestation takes six months; a single fawn is typical, although twins have been reported in Algeria. The newborn is well developed at birth, with fur and open eyes. Within the first hour, the fawn attempts to stand, and it will suckle on this first day of life. In the first two weeks, the young gazelle lies curled up in a scrape on the ground or beneath bushes while the mother grazes close by. The young then starts to follow its mother around and begins to take solid food. After around three months, the fawn stops suckling and is fully weaned. Some dorcas gazelles are also known for their dangerous behaviors when surrounded. There have been many reports of deaths involving them.


The population of this gazelle has declined throughout its range. Their natural predators include humans, cheetahs, leopards, Arabian wolves, and lions. Due to human hunting, few large cats remain to prey on dorcas gazelles. Mostly unhealthy gazelles are caught successfully by predators, since the healthy gazelles tend to escape them. To escape the cheetah, the fastest of carnivores, they run extremely fast and make zigs-zags, as does the Thomson's gazelle.
The serval and caracal also prey on this species. The biggest modern threat to this gazelle is ever-expanding human civilization, which shrinks the gazelle's habitat by converting it to farmland, and by introducing new flocks of domestic sheep and goats which compete with gazelles for grassland.


The scientific name of the dorcas gazelle is ''Gazella dorcas''. It is a member of the genus ''Gazella'' and the family Bovidae. The species was first described by Swedish zoologist Carl Linnaeus in the 10th edition of ''Systema Naturae'' in 1758.

Although zoologist Theodor Haltenorth considered ''G. d. pelzelnii'' to be an independent species, the following six subspecies are identified:

⤷ ''G. d.'' subsp. ''beccarii'' De Beaux, 1931 – Eritrean dorcas gazelle
⤷ ''G. d.'' subsp. ''dorcas'' – Egyptian dorcas gazelle
⤷ ''G. d.'' subsp. ''isabella'' Gray, 1846 – Isabelle dorcas gazelle
⤷ ''G. d.'' subsp. ''massaesyla'' Cabrera, 1928 – Moroccan dorcas gazelle
⤷ ''G. d.'' subsp. ''osiris'' Blaine, 1913 – Saharan dorcas gazelle
⤷ ''G. d.'' subsp. ''pelzelnii'' Kohl, 1886 – Pelzeln's gazelle
