Common Raven

One of the most intelligent birds known, common ravens demonstrate problem-solving abilities rivaling great apes, including tool use, planning, and deceptive behavior.

They form complex social hierarchies, engage in cooperative foraging, and have been observed engaging in play. Their intelligence and black plumage have made them figures of mythology across many cultures.
