The Blue Wildebeest (sometimes called a Brindled Gnu) is actually a large antelope. They are native to the open plains and dry woodlands of East Africa and have a lifespan of more than 20 years. The largest population of Wildebeest is in Tanzania with over one million animals in the Serengeti. Probably the most conspicuous feature of the Blue Wildebeest are the large horns shaped like parentheses, extending outward to the side and then curving up and inward. In the male the horns can attain a total span of almost 3 ft. while the female’s horn width is about half the size of the male. There are currently only two Blue Wildebeests on the 10xXx Ranch but they are easily seen because they enjoy a personal pasture.
