The saiga antelope (/ˈsaɪɡə/, Saiga tatarica) is a critically endangered antelope that originally inhabited a vast area of the Eurasian steppe zone from the foothills of the Carpathian Mountains and Caucasusinto Dzungaria and Mongolia.
They also lived in Beringian North America during the Pleistocene. Today, the dominant subspecies (S. t. tatarica) is only found in one location in Russia (in The Republic of Kalmykia) and three areas inKazakhstan (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 People’s Republic of China and southwestern Mongolia. It was hunted extensively in Romania and Moldova until it became extinct in those regions in the end of the 18th century. The Mongolian subspecies (S. t. mongolica) is found only in western Mongolia. source
