Who are the masterminds of the bird world? What different types of behaviour can be interpreted as ‘intelligence’, as we would recognise it? This book provides a intriguing and beautifully illustrated investigation into some extraordinary bird behaviours and abilities, from problem-solving and tool use to self-recognition and empathy. As research explodes the myth of our feathered friends’ ‘bird brains’, the fascinating studies outlined may even help us re-evaluate how we identify and classify intelligence in other animals. Dr Nathan Emery is Senior Lecturer in Cognitive Biology at Queen Mary, University of London. Author of two previous books and over 80 other publications, he sits on the editorial board of the journals Animal Cognition and the Journal of Comparative Psychology.
