I have only seen House Wrens on Compton Mt during the spring a couple of times. A few years ago a pair showed up here in the spring. A short time later the male was still singing, but he was alone. He built a nest in a bluebird box, but after singing near it for a couple of weeks without attracting a mate he left. This morning I stepped outside and heard a House Wren singing in the shrubs along the driveway. I didn't hear him later in the day so he may have been passing through. Roger Mayhorn Compton Mt
