The saiga antelope, or saiga, is a critically endangered antelope which during antiquity inhabited a vast area of the Eurasian steppe spanning the foothills of the Carpathian Mountains in the northwest and Caucasus in the southwest into Mongolia in the northeast and Dzungaria in the southeast. During the Pleistocene, they also occurred in Beringian North America and the British Isles. Today, the dominant subspecies is only found in one region in Russia and three areas in Kazakhstan. A portion of the Ustiurt population migrates south to Uzbekistan and occasionally Turkmenistan in winter. It is extirpated from China and southwestern Mongolia. The Mongolian subspecies is found only in western Mongolia.
