Now, please don’t give me grief about the old wolves and mice thing. There are wolves that live on rodents. However, they aren’t in North America. They are African. Ethiopian wolves live in large packs (for some reason), and live on nothing but rodents and other small prey.
If you read the book on which this is based, the wolves do hunt caribou.
For those who quibble with the veracity of the work– it’s not entirely nonfiction. It’s partially ethnography and folklore. Most of the wolf “observations” are actually how the viewed Ihalmiut them. And they knew the wolves before we began to select them for reactive and nervous behavior through our persecution. So who knows what the truth was?
It’s basically a good read. And the film is good, too.
