We all know the story about dinosaurs dying out because wicked little furry things ate their eggs, right? Well that got played out in miniature in New Zealand when Europeans arrived bringing rats.

Thankfully some survived on remote islands, and now it seems they are beginning to re-colonize the mainland.
