When not migrating they can be found singly or in small herds, up to 10-15 head. Young of gazelles are usually born from April to June and in a few days after birth they have sufficient strength to follow the mother. Within a week they are able to run almost as rapidly as their mothers. The life span is 10-12 years. They can resist long periods of drought without drinking, but their water requirements are much higher than those of the Dorcas gazelles.
Gazelles are medium-sized antelopes especially adapted to dry conditions.
The name gazelle has come to suggest grace and beauty, for all the species are dainty, alert, and graceful. Dama Gazelle has five subspecies. Two of the five have already been exterminated. The Antilopini are an ancient group that branched off from neotragine ancestors in the Miocene. The Behavior Guide to African Mammals.
