Vultures Use Tools to Roll Wool and Open Eggs
The Egyptian vultures use a few tools to make their lives easier. One of the mainstays of the bird’s diet is the giant ostrich egg. The egg has an extremely thick shell that usually requires a hammer or drill for humans to crack. Egyptian vultures solve this problem by making their own hammer using flat, rounded rocks held tightly in its beak to pound the eggshell until it cracks. The birds have also been observed engaged in the unusual activity of rolling wool with sticks. The wool is used in the construction of the vulture’s nest.
