Ravens are smart. Common ravens have among the largest brains of any bird species and they have been shown to fashion tools of leaves to use them to extract grubs as well as solve complex puzzles. Young ravens are exceedingly playful and have been observed sliding down snowbanks, feet akimbo, squawking in delight. They even play games and seemingly tease other species, such as boldly playing catch-me-if-you-can with wolves and dogs…and then there’s the talking.So smart, in fact, is the Covus Corax, that a single bird, a raven named Grip, is responsible for two, count them two, contributions to the cannon of classic literature. Not even Lassie can compete with that.
