Domestic foxes would probably argue that in fact, they get free lunches all the time, but their cousins in the wild don’t have it so easy. Foxes in the wild not only have to find their own food, but catch it… or in the case of arctic foxes, occasionally steal it from larger predators without getting becoming lunch themselves.
For more info on arctic foxes, check out this clip from National Geographic:
Or this one, of tundra swans defending their nests against a hungry fox:
There’s also a lot of cool info about feeding behaviour of foxes at the website for the Karrak Lake Arctic Fox project, which was run by my science friend, Gustaf Samelius. Gustaf, by the way, is now studying snow leopards, which are SO CUTE.
