These cockatoos are no less than many species and can solve several vagueness and puzzles. This fact was unveiled by the researchers as they tempted the cuckatoos to provide them with nuts if they would be able to solve the puzzle. This worked. This was a positive experiment where cuckatoos responded well. They showed a trait that humans possess.

The captive Goffin's cockatoos (Cacatua goffini) were shown a cashew nut with many interlocking devices in the way. They were shown the nut through a transparent door. Then the researchers also gave them a trial of a completely different nature. They even managed to do that. Any modifications in the previous trial are accepted with elation and the puzzles are solved by the birds.

Professor Alex Kacelnik from the University of Oxford's department of zoology studied the behavior pattern of birds. The researchers from the University of Oxford in the UK, the University of Vienna in Austria and the Max Planck Institute in Germany worked on this subject. They seemed to be excited about the findings. But the lead author of the experiment has said that the subject is not yet over. A lot needs to be done in this regard.
