It's been a while since I've heard anything about Dr Irene Pepperberg and her African Grey Parrot, Alex. So I was happy to find this very recent article about the famous bird on the web.

Dr Pepperberg states that her research has shown that African Greys have cognitive abilities similar to small children. The article also goes into what led her to begin her research with parrots, the importance of Alex's concept of "zero" and more.

If you are a fan of this particular African Grey Parrot, you can check out the full article titled "Gawk! Alex is smarter than the average bird."
