The Addax is a critically endangered antelope native to the Western Sahara. With only an estimated 200-300 Addax left in the wild, every birth in captivity helps ensure the survival, and potential re-population, of this species. This little boy was born June 17th at Chicago's Brookfield Zoo. Lots of happy antelope tail-wagging in this video.
