Sable antelope

Both sexes carry long, ridged horns that arc back in a near semicircle, up to about 5 feet in a big bull, so the coat is what tells them apart: mature bulls are chestnut to jet black, while cows and young are bright chestnut to dark brown. Against that dark body the white face with a broad black stripe down the nose stands out at a distance. Calves start out reddish-brown and almost unmarked, gaining the white markings and darker coat as they age. Sable keep to light wooded savanna and miombo woodland in southeastern Africa and usually avoid open grassy plains, so they are a woodland-edge sighting rather than a plains one.
