Lap-wing Nubian Vultures perched in a treetop on the Masai-Mara, Kenya. This is also called the Lapid-faced vulture. Although they aren't beautiful, all vultures perform an incredibly important function--they keep Africa clean. By eating carrion, they remove decaying carcasses from the environment. All cultured have heads without feathers so they do not contaminate themselves shen eating rotting flesh.
