‘There is the mammal way and there is the bird way.’ This is one scientist’s pithy distinction between mammal brains and bird brains: two ways to make a highly intelligent mind. But lately, scientists have taken a new look at bird behaviours they’ve previously dismissed as anomalies. What they’re finding is upending the traditional view of how birds live, how they communicate, forage, court, survive. They’re also revealing the remarkable intelligence underlying these activities, abilities we once considered uniquely our own – deception, manipulation, kidnapping, infanticide, but also, ingenious communication between species, collaboration, altruism and play. Drawing on personal observations, the latest science, and her bird-related travel around the world, Ackerman shows there is clearly no single bird way of being. In every respect, in plumage, form, song, flight, lifestyle, niche, and behaviour, birds vary.
