Earlier quoted context omitted.
And all alpine chalets and cabins in Kea habitated areas have warning signs about leaving windows open with pictures of the share devastation they cause when they get inside. Where I live we have Kaka which are related to Kea. All they do is tear trees to shreds.
This is a problem with baboons in chalet and cabin areas in the southern African bush as well. They're able to get into a window (if not locked) and devastate a cabin in their search for food, they're able to open chip and food packets, unscrew jar lids etc. In their case I think the opposable thumbs are what really come in handy.
they literally come in handy :-)
