A Review Psychology Today, May/June 2006, p 34 Why does a raven bathe? To escape parasites — or simply because it feels good? Pleasure is just as crucial as are pain and fear to understanding animal behavior, argues Balcombe, who is affiliated with the pro-vegetarian Physicians Committee for Responsible Medicine. He attacks the idea that animals are mere automatons enacting preprogrammed behaviors, and the entertaining examples of animal bliss he provides — from drunken parrots to the gentle caresses of fiddler crabs — bring a pleasure all their own.
