My favorite kea story:
I did a hike while on vacation on the South Island back in 2007 (Avalanche Peak, IIRC) where several kea greeted us at the top. They have a reputation of being mischevious. Here is one having a go at my boot.
Ignore my finger there
There were a few people up there eating lunch and one guy dropped his camera case. It dropped a little way down the hill; not so far that he wouldn’t be able to retrieve it but far enough that he had to get up.
He started towards it but a kea quickly hopped down there and grabbed it. He put it on his head and wore it like a hat for a bit
and then as if to mock the guy he tossed it off the side of the cliff. I almost fell off myself laughing.
I’ve loved those birds ever since. They are wonderful, but hang on to your stuff if you see one.
