I found some really nice bird houses on E-bay and purchased one for the Carolina wren that I wrote about earlier. I hope he will stay. I had purchased some bluebird houses earlier from the same person (in Oregon) and was very pleased with the quality. So I went back and bought 4 wren houses. After a bit of research, I read that wrens prefer a sheltered site for their nests, preferably among shrubs where they will have protection. I put this house in the secret garden area on the fence which is partially hidden behind evergreen plants.
