Quale uccello è noto per rompere le noci sulle rocce?

Crow. Many crow species are famous for using “anvils”—flat rocks—where they place hard nuts and hammer them with their beaks or even with stones to crack them open. Some, like Japanese carrion crows, drop walnuts onto roads and wait for cars (and traffic lights) to do the cracking, a striking example of avian problem-solving. This sets crows apart from similar birds: woodpeckers peck wood for insects (acorn woodpeckers store acorns in trees, not on rocks), blue jays mainly crack and cache nuts, and magpies are less known for nut-smashing. Memory tip: think “crow as a blacksmith”—using an anvil (rock) to break tough shells—highlighting the crow’s exceptional intelligence and tool use among birds.
