According to the BBC, scientists discovered that "cockatoos could complete the five-step mechanical puzzle to reach their goal - a cashew nut treat."
Researchers presented 10 birds with a box containing a cashew nut treat, which they could reach by removing five different interlocking devices.
One of the Goffin's cockatoos, called "Pipin", solved the complex mechanical puzzle unassisted within two hours.
Several other birds mastered the task after observing peers or being presented with the locks incrementally.
The study, carried out by scientists from the University of Oxford in the UK, the University of Vienna in Austria and the Max Planck Institute in Germany, is published in the journal PLoS One.
To reach the nut, the captive Goffin's cockatoos (Cacatua goffini) had to remove a pin, followed by a screw, a bolt, then turn a wheel and move a latch sideways.
