This book explores the frontiers of research on animal cognition and emotion, offering a surprising examination into the hearts and minds of wild and domesticated animals. Have you ever wondered what it is like to be a fish? Or a parrot, dolphin, or an elephant? Do they experience thoughts that are similar to ours, or have feelings of grief and love? These are tough questions, but scientists are answering them. They know that ants teach and rats love to be tickled. They have discovered that dogs have thousand-word vocabularies and that birds practice their songs in their sleep. But how do scientists know these things? This book takes us on a dazzling odyssey into the inner world of animals and among the pioneering researchers who are leading the way into once-forbidden territory: the animal mind. Here the author transports us to field sites and laboratories around the world, introducing us to animal-cognition scientists and their surprisingly intelligent and sensitive subjects. She explores how this rapidly evolving, controversial field has only recently overturned old notions about why animals behave as they do. In this she brings the world of nature brilliantly alive in a nuanced, deeply felt appreciation of the human-animal bond.--From book jacket.
