The Afroalpine highlands of Ethiopia are home to the last remaining Ethiopian wolves.The highest known population of Ethiopian wolves live in the Bale Mountains in Southern Ethiopia, just southeast of the Rift Valley.
They are red, these wolves, with black-and-white tails, and white blazes on their chests. The fur on their throats is white too, and sweeps in a curve toward their eyes, giving them the look of laughing clowns. But it's the sassy hue of their coats that catches your eye. We're the top dogs here, their color proclaims. And they are. For these are Ethiopian wolves: the only species of wolf found in Africa.
