And I'm pretty sure that elephants, whales etc. have bigger brains than humans. I guess when it comes to intelligence, size doesn't matter.There's a yellow-naped Amazon that my Mom bought. He showed not only intelligence but also feeling and wit. He used to sneak up on my dog when she was sleeping and bite her tail, then fly away shrieking in delight.
He also had a very good memory. He'd remember visiting relatives from a couple years earlier.
He also showed strong emotional reactions-- depression, joy, etc. He might not be good at calculus, but I don't see how any person could know him and not see value in his life.
