The Kea; The worlds only snow-inhabiting parrots, they live in the alpine environments of the south island of New Zealand, and they are thought to be the Smartest parrots in the world, so smart that they are put up there with Chimpanzees and Dolphins.
Scientists have set up many puzzles which have determined that Keas are one of the best problem solvers, even when completely wild. Demonstrating group coordination, where one of them would hold open a lever while the other gets the food out, then they share!
Watch this David Attenborough documentary, “Kea - The Smartest Parrot" skip to 6 minutes in if you just want to watch them dismantle puzzles set up by researchers.
They are so smart that they actually get bored with their daily lives of gathering food and making babies, and so they play games, which residents surrounding Mt. Cook despise as it usually involves taking apart cars, TV aerials, and other things that are usually expensive to replace.
