Can an old rook learn new tricks? 🐦‍⬛ Meet Leo, the rook who follows human voice commands – just like a dog. Cambridge researchers found that Leo could learn 3 commands by sound alone, without relying on gestures or lip movements. And he wasn't the only one – two other rooks picked it up too. This suggests that animals don't need domestication to follow our voices – some species may simply use their natural communication skills. #CambridgeUniversity #Cambridge #UniversityOfCambridge #Birds #Orn
