Ravens are self-aware and perfectly recognize their reflection in the mirror. They know how to make and use tools. For example, crows use sticks to knock apples off a tree. They can also perfectly distinguish volume, weight and material from which the object is made. That is why these birds will never put a piece of wood in a container to raise the water level in it.

And this is not just a mechanical work of muscles, but a real emotional response to an external stimulus.
