Bangkok, Thailand is a city of around 15 million people.  A thriving bird population also lives there.  People are encouraged to feed the birds and vendors selling small bags of bird food abound.  These city birds also eat food which might otherwise go to rodents.  Thus the Pigeons serve as food for raptors, human entertainment and as pest controllers.  Such feeding activities are illegal in San Francisco, a city of 800 thousand people.  People who would feed them must do so with one eye on the birds and one eye watching for the police.
