There is a park in San Juan, PR that has been build for pigeons. The homes were cut into the stone walls and hundreds live there. Of course, the kids come to get their photos made with the pigeons all over them...and probably some other stuff on them, also. I used an 80-200mm Nikkor zoom on my D-600 so I could stand far enough back to dodge the "falling material" and got this photo of the cozy couple on a sunny Sunday afternoon.
