After reading an interesting article in National Geographic magazine about animal cognition, I listened to this piece from NPR. It's about Alex the African Gray parrot who died last year. In Alex's 30 years, he was able to learn sizes, colors, shapes, could count and could grasp the concept of zero (I'm paraphrasing from the NG article).
Among the other animals featured in this article we sheep who can recognize individual faces long term, the giant pacific octopus that has a distinct personality, uses tools and can recognize individuals, the western scrub jay that can recall the past and plan for the future...the other start of the article were border collies (it does seem to be limited to this breed- the high word recognition) who have the word recognition of toddlers.
