People like to use the term 'Bird Brain'. I bet none of them has ever met a grey parrot before! These guys are very smart, and may have a better vocabulary than some teens we hear from today! In any case, researchers have put these parrots through all kinds of intelligence tests, so if you want to show us you're smarter than a grey parrot, you'll have to answer at least 10 of these 12 questions correctly!
Hint: Pay close attention to the photos and try to memorize everything you see!
