Rüppell's vultures, named after a German explorer, are large African vultures. Much of their day is spent soaring in the air on thermal currents, at some surprisingly high altitudes, and using their keen eyesight to spot long forgotten carcasses. They home in on the carcass in flocks and with all the tasty flesh gone, these scavengers will eat what's left over, using their powerful hooked beaks to tear skin and break bones with ease. A decline in the range of these very social birds is partly a result of their being used in black magic.
