The book covers with competence the most traditional topics of avian intelligence, including nest building, mimicry, tool use, imitation, play, social and vocal learning but also more neglected topics, such as brain and behavioural asymmetries. [...] Overall, the book provides a scholarly but also very enjoyable reading on the intelligence of birds, and should thus be a recommended reading even to non-specialists. - Giorgio Vallortigara, Centre for Mind and Brain Sciences, University of Trento, Italy
