A Japanese university professor has discovered that kea – New Zealand alpine parrots – are even smarter than previously thought.

“The most challenging set-up involved two bolts blocking each other such that one needed to be slid open before the second would release.
“Mr Miyata, a psychology researcher, found that keas cracked this problem faster if they were allowed to study the set-up for a while before attempting to break it.
“When they had a chance to think over the set-up before tackling it, the birds corrected inappropriate responses more quickly.”
