"THIS IS NOT ONLY AN IMPORTANT BOOK, IT IS MARVELOUS! IF ANIMALS COULD READ THEY WOULD BE FILLED WITH JOY AND GRATITUDE TO THE AUTHORS -- AS I AM. IT IS SCHOLARLY, VIVID, AND COMPELLING. PLEASE' READ IT." -- JANE GOODALL No one who has lived with animals would deny their capacity to feel. But scientists continue to do just that. This groundbreaking book, the first since Darwin's time to explore emotions in the animal kingdom, proves what laypeople have always believed: that animals love and suffer, they are lonely, jealous, disappointed, or curious; they mourn, they worry, they hate, they anticipate happiness... they feel. Meet: - Buffalo who ice-skate -- for the joy of it - Flint, a chimpanzee who mourned the loss of his mother until he died from grief - Koko, a bashful gorilla proficient in sign language who loves to play house with dolls -- but only when nobody is looking - Crows who damaged the gold onion domes of the Kremlin - by using it for a slide - Alex, an African grey parrot with an astonishing vocabulary who, when left at the veterinarian's office, shrieked, "Come here! I love you. I'm sorry. I want to go back." Based on scientific studies and anecdote-filled field notes of scores of biologists, ethnologists, animal trainers, and animal behaviorists, this extraordinary book -- at once heartrending, impeccably researched, and compulsively readable -- shows just how deeply animals, in the wild or in captivity, experience emotions ... including elephants who weep with tears that wrench our hearts. FASCINATING... COMPASSIONATE... A BOOK TO BE READ MORE THAN ONCE." -- The Philadelphia Inquirer COMPELLING EVIDENCE... CAREFUL DOCUMENTATION... ANYONE WHO READS THIS BOOK WILL BE FOREVER CHANGED." -- Detroit Free Press
