Herds of mustangs have become a symbol of the American West, but because of their ancestry they are not considered a separate species from the domestic horse.ANIMAL FACTS
Wild horses lived in North America around 11,000 years ago. European explorers reintroduced horses to this continent about 600 years ago. Over time some escaped, and formed independent herds. Mustangs are therefore feral horses, that have reverted from a domesticated state back to living in the wild. By 1900, there were an estimated two million mustang horses in North America, which were often caught and sold, but today there only around 33,000.VITAL STATISTICS
