At many zoos peafowl are allowed to roam loose on the grounds where they pretty much fend for themselves to find food and shelter. Keepers in the animal hospital were having a hard time getting an ailing peacock to eat. They offered him every sort of normal fowl food that they could think of and he refused them all.
Finally, they stopped to consider what sort of food the bird had been used to eating. They went to a nearby food stand and got some popcorn and French fries. The bird, of course, began eating immediately.
