Its not unusual to see crows hanging on on the deck railing. They are often there by the dozens. They like to smooth down their beaks on the metal railing. We've also had kingfishers land and watch the water for a meal. We've see eagles land and hang out until they see a shadow from the front window and usually fly off before I can snap a pic.
This is a Great Blue Heron - quite large. I took this from the second story loft. I figured if I went downstairs it would see me and fly away. It must have been full because its facing away from the water.
