. Today the nominate subspecies (Saiga tatarica tatarica) is only found in one location in Russia (steppes of the North-West Precaspian region) and three areas in Kazakhstan (the Ural, Ustiurt and Betpak-dala populations). A proportion of the Ustiurt population migrates south to Uzbekistan and occasionally Turkmenistan in winter. It is extinct in China and southwestern Mongolia. The Mongolian subspecies (Saiga tatarica mongolica) is found only in western Mongolia.

Physical characteristics

The saiga typically stands 0.6-0.8 meters at the shoulder and weighs between 36 and 63 kg. Their lifespan ranges from 6 to 10 years. Males are bigger than females and are the only sex to carry horns. The horn

s eating several species of plants, including some that are poisonous to other animals. They can cover considerable distances and swim across rivers, but they avoid steep or rugged areas. The mating season starts in November, when stags fight for the possession of females. The winner leads a herd of 5-50 females. In springtime the mother gives birth to, in two thirds of all cases two, or in one third, one single foal.
