                                    Egyptian Vulture is famed for its ability 
                                    to open ostrich eggs using stones as missiles. 
                                    Birds pick up stones in their bills and 
                                    throw them forcefully towards the ground. 
                                    Normally they miss, but this bird is nothing 
                                    if not persistent. It is the only bird confirmed 
                                    to possess this ability and much debate 
                                    exists over whether the techniques is learned
