Here‘s a delightful article about ravens and their intelligence. My favourite two tidbits:
1) Ravens apparently think wolves stupid. Ravens take elaborate measures to deceive fellow ravens about what they’re up to when they’re spying, hiding food, and so forth. But when they’re spying on a wolf that is burying food, they watch him openly — and dig up the food as soon as he leaves. Those dumb wolves that just can’t keep track of their food …
2) Especially courageous ravens wanting some excitement will grab boars by their tails and let themselves be towed along through the snow on their backs.
What’s not to love about playful elitists like that?
