Crows and ravens
Ravens and crows are living proof that it’s not the size of your brain that counts but how you use it. These animals learn quickly, with research suggesting four-month-old ravens could be as intelligent as some adult apes. Experiments have also shown that ravens can plan for the future with tools they’re taught to use by humans. Crows on the other hand have an excellent memory and remember human faces, identifying certain people as friend and others as foe.
