Wild cockatoo parrots remain the only non-primates who make their own tools.
Many animals use strange objects for their own purposes. Although, until very recently, it was believed that it was only primates who purposefully created tools. Recent studies from Indonesia have now proven this belief to be completely wrong.
During the studies, the cockatoo's skills were revealed. They started to feed on "sea mangos". The nutritious seeds of the fruit are hidden inside the pit that is too tough to be crushed by their beaks. Nevertheless, the clever parrots discovered how to get to the tasty treat utilising any resources at hand.
They used several branches, one which was pointed and used to make a hole in the pit. The second was employed as a wedge, and the third was to scoop up the seeds. However, of course, not all parrots were able to come up with such a complex strategy. Still, the intellectual potential of the cockatoos proves to be much greater than was previously thought.
