Some previous owner was obviously into bird watching. These are some of the bird houses that came tumbling down when we took out the old trees earlier this year. There are also bird feeders scattered throughout the yard that I never fill. I think there's plenty to eat out here without me feeding them - except for the hummingbirds. I do put a feeder out for them just because I love watching them. Although, since I've got real flowers out back now, they seem to prefer the flowers over the feeder.
