About this item

How animals communicate and learn -- sometimes better than humans do, actually. This fascinating book, written by a world authority on animal intelligence, brings together the cumulative research on the comparative intelligence levels of nonhuman "smart" species. Sally Boysen reveals how these intelligent animals communicate, learn behavior, show feelings and emotions and, for some species, how they use tools, count and sometimes pick up a foreign language. Fully illustrated with photographs and step-by-step graphics, the book draws on data from historical and current experiments and observations to examine intelligence in the great apes (gorillas, chimpanzees and orangutans) and in a surprising list of other species, including sea otters, eagles, elephants, dolphins, birds, bees, beetles, rats, raccoons and parrots.
