Study finds parrots weigh up probabilities to make decisions

Researchers say it is the first time such skill has been shown outside of humans and great apes

Some parrots weigh up probabilities to help them make choices, researchers have found, in a study that provides the first evidence of this skill outside great apes.

Among previous studies, African grey parrots have been found to selflessly help their peers complete tasks and seem able to identify colours and count. Cockatoos meanwhile can keep track of an object's location - even when it is hidden - and have been found to invent dance moves.
