The Peekaboo Cockatoo

Some birds are just smart and this cockatoo proves the point.

Parrots are arguably one of the smartest birds you can find. These beautiful birds can even learn to solve problems when there is an incentive to do so.

These birds have an average lifespan of between 40 to 60 years.
The natural habitat of cockatoos ranges from dry bush land in Australia to humid forests in Indonesia.

Therefore their diets can vary considerably, consisting of fruit and fruit seeds, nuts, flowers, corn where they can find it.

Teams from from Oxford University, the University of Vienna and the Max Planck Institute collaborated on a study, which involved challenging cockatoos to pick a series of interlocking devices, each of which jammed the next lock along.

To retrieve the nut from behind the glass, the birds had to remove a pin, then a screw, then a bolt, before turning a wheel 90 degrees and shifting a latch sideways.

The birds worked determinedly and consistently, employing a “cognitive ratchet” approach, meaning that once they had discovered how to crack a lock, they then didn’t struggle with the same device again in future.

This, according to the researchers, is consistent with the birds having an understanding of the goal they were pursuing.
