Grants Gazelle (Gazella granti) resemble Thomsons gazelles and the two species are often seen together. They are similarly colored and marked but Grants Gazelle (Gazella granti) are noticeably larger than Thomsons and easily distinguished by the broad white patch on the rump that extend upward, beyond the tail and onto the back. The white patch on the Thomsons stops at the tail. Some varieties of Grants Gazelle (Gazella granti) have black stripe on each side of the body like the Thomsons gazelle.
In other Grants Gazelle (Gazella granti) the stripe is very light or absent. A black stripe runs down the thigh. The Grants Gazelle (Nanger granti) is a species of gazelle. Their populations are distributed from northern Tanzania to southern Sudan and Ethiopia and from the Kenyan coast to Lake Victoria.
The various types of Grants Gazelle (Gazella granti) differ mainly in color and in the size and shape of the horns. Grants Gazelle (Gazella granti) are large, pale, fawn colored gazelles with long legs. The males are larger and heavier and their horns longer than the females. Grants Gazelle (Gazella granti) may remain in areas where food is plentiful. Mature males establish territories they may hold as long as eight months. A male tries to detain the female herds of 10 to 25 individuals as they pass through these territories while they move about to feed. At the same time males chase off rival males and try to mate with females in estrus.
Grants Gazelle (Gazella granti) have developed several ritualized postures. For example, the territorial male stretches and squats in an exaggerated manner while urinating and dropping dung. This apparently warns other males to stay away and reduces the number of confrontations. Younger males will fight, but as they grow older the ritualized displays often take the place of fights. When fighting does occur, it also is ritualized. Grants Gazelle (Gazella granti) starts with pretend grooming, repeated scratching of the neck and forehead with a hind foot and presenting side views of the body. If neither combatant is intimidated, they may confront one another and clash horns, trying to throw the other off balance.
