Keas are remarkable birds: playful, belligerent and smart. So smart in fact that some scientists believe they have the intelligence of a 4-year old human.
The kea is a species of large parrot in the family Nestoridae found in the forested and alpine regions of the South Island of New Zealand. About 48 cm long, it is mostly olive-green with a brilliant orange under its wings and has a large, narrow, curved, grey-brown upper beak.
