We don't have too many here. I love watching the ones that land on my grandma's roof. There have been pigeons by her house since long before I was born. I always loved watching them stand on her roof. There are so many colours too. Autumn caught an injured racer last summer and we kept it until a guy from the local racing club came to get it. Beautiful bird. I had no problem letting Autumn pick it up to bring to me. I don't think they are any dirtier than other flock birds.
