This is the second year in a row the House Wrens have nested in this plastic hat. Why? Who knows. Anyway, I could sit right out there and watch the comings and goings of the wrens. They ignored me and went about their business. I was going to have the shrubby dying plant near their nest cut down until I discovered the wrens nesting there. They sat in it all the time to guard the nest. It can go in the fall. Maybe the wrens won't like this site next year.
