There are only between 1,000 and 5,000 kea in the world. The only place (outside of a few zoos) that you can see them is in the mountains of New Zealand. Yes, where Sauron lives. Not only did they have to contend with widespread eradication by the New Zelanders (who have since changed their ways) and suffer from lead poisoning, they also must be constantly on guard against orcs and giant spiders.
