How do crows use tools?

Crows are among the few animals known to use tools. They have been observed fashioning sticks, leaves, or other materials to extract insects from crevices. Some species, like New Caledonian crows, shape hooks from twigs to access food. Crows also use their problem-solving skills to manipulate objects, such as dropping nuts on roads for cars to crack them open. This advanced behaviour demonstrates their remarkable intelligence and adaptability.
