Grevy’s zebras are an endangered species that live only in northern Kenya and a few small pockets of Ethiopia. They are the largest wild member of the horse family and can weigh up to 990 pounds. Stallions that are unable to establish a territory become free ranging and are called bachelors — which appeared to be the case here, as this guy was wandering solo across the short grasses of Lewa Wildlife Conservancy in Kenya.
