Italy has some very strict rules, one of them being that you are not allowed to feed the pigeons in St. Marks Square. That being said, there are vendors who will happily sell you bird feed! The dance between feeder and feedee goes on all day and it's fascinating to watch. These kids didn't know each other, but they were happy to spend some time together risking poop and histoplasmosis. Consult you physician before approaching the local wild life.
