Wild Bird Feeders

My bird feeder and calm front yard have attracted a pair of ducks who have been coming around for about a week now. This is highly irregular for my area as there are no ponds or such nearby, just concrete in every direction. I am feeding them seed mix, bread and water. They really seem to like the water. They can both fly and just must be living around the neighborhood for now. Nibbler makes a cameo as he shows interest in the ducks.
