Wild cockatoos excel in intelligence tests, countering theory living with humans makes birds smarter

Daily Mail - Science & tech

A longheld theory that animals raised in captivity perform better in cognitive testing may need to be rethought. A new study organized by the University of Veterinary Medicine in Vienna found evidence that wild animals perform just as well at intelligence tests as their lab-raised counterparts. To test the theory, researchers compared two groups of Goffin's cockatoos, a species often found in the tropical jungles of Singapore, Indonesia, and Puerto Rico. The team compared a lab-raised'colony' of 11 cockatoos at their lab in Vienna to eight wild cockatoos recently taken into captivity at a field laboratory in Indonesia. The researchers compared the performance of both groups in a series of simple problem solving tests and found the wild cockatoos were just as clever as the lab-raised ones.
