Hi, i hope this isnt a silly question but..I live across the road from an old empty building which is now home to pigeons. One window is open so they can get in and out. Over the past couple of weeks ive noticed that one pigeon sits out all night on the ledge next to the open window. Can anyone plz tell me if he(?) would probably be either a tame old boy lost (too high n dark to see if he has ring), orphaned, widowed, out casted or on gaurd on nightshift? its just one of those pondering thoughts that keeps me awake. folks think im mad that i get upset at the thought of him being lost and lonely not being with the other pigeons
