Based on a personal experience. An American friend was very impressed by the pigeons she saw on our trip. When we asked why she pointed at a very dirty and scruffy looking pigeon with one foot and said “That’s what they look like in American cities”
Or you could just go to the rural areas of America. I used to visit a dairy farm regularly, and plenty of pigeons there were as fit as the Norwegian example.
Over here in New York City we have a bunch of dumb looking pigeons but they're OUR dumb looking pigeons, same with our obese rats, they're quite poetic if you think about it; shows how us new yorkers are no different from the rats and pigeons, we're all just surviving here lol
