Yes, nothing more accurate in describing Egyptian Vulture, Neophron percnopterus, of obtaining his meal of the day. Egyptian Vulture is one of the few birds in the world to figure out the intrinsic value behind a stone. The Egpytian Vultures are known to use stone to break open Ostrich’s egg by throwing the stone towards it. You can see from youtube using the link below:

We can see how the Egyptian Vulture and the Eagle choose to move away and surrender their bounty to the much large (and presumable scarier) Lappet-faced Vulture, Torgos tracheliotos. Well, you certainly don’t want to mess with the wrong guy
