When you're doing this, please be careful to pick up the leftover peanuts. One of our neighbors does this and our property is constantly being invaded by rats who are attracted to her discarded peanuts.
When I was a kid, old ladies would sell grain in plastic cups for people to throw to the pigeons. The moment you poured some grain on your hand, you were suddenly surrounded by a hundred birds. It was an attraction for both tourists and children. I haven't seen that practiced in a decade or more, I suppose feeding the pigeons became illegal at some point.
