New Zealand is a kingdom of birds. Evolution provided the land with no big predators–in fact, no mammals at all except for a few tiny bats. Birds ruled. They didn't even need to fly to live safely and well in New Zealand; flightless birds–penguins, kiwis, and nine species of giant moa, among many others–found food and nesting sites right on the ground all over the place.

Humans arrived with guns and quickly shot all the moas. Also, people began harassing the other birds with imported varmints that ate eggs and/or birdmeat. We are a pretty pathetic excuse for a species.

But some of the birdlife seems to have evolved to seek a certain revenge. Case in point is the kea, the world's only alpine parrot, endemic to New Zealand's high country. Wherever roads lead to mountain passes or overlooks, keas are hanging out in the parking lots, waiting for cars to chew.

Keas gnaw on and can completely destroy the rubber fittings on automobiles, such as gaskets around windows and antennas. They also eat ice cream a scoop at a time off a handheld cone, and they can figure out how to open backpacks and devour all the food inside.
