Animal Fun Facts
Ravens use stones as tools and can even solve multi-step problems. Ravens are birds belonging to the Corvidae family. Scientists have discovered that they can use tools to obtain food in certain experiments. For example, they might first use one tool to get another, more suitable tool, and then use the latter to get food they couldn't reach otherwise. They don't just peck at anything they see; they can select tools based on the situation, demonstrating complex problem-solving abilities.
