Bird BrainsTwo stories today suggest that birds may be man's best friend. In England, Fred, an African Grey parrot, became so depressed when his owner died that he had to be prescribed a twice-daily liquid dose of Clomicalm, the bird version of Prozac. Further south in Wales, Smokey, a grey cockatiel, went missing for two days after flying out of his owners' front door... and, after he was found, chirped his own name, convincing his rescuer that she had found his owner. "He's a one-in-a-million bird. My heart went when he flew away," said owner David Edwards after picking up Smokey. "I don't mind admitting I shed a few tears on my way to pick him up."
