Nowa home?

This bird house is directly above and to the side of my back door. Supposed to be for decoration. I never thought I'd have a fine feathered guest, but this little one has been in and out of it for a few wks now. I have never seen any nest building materials going in and I don't want to scare her away by looking so I'll have to wait. There is so much activity at this door with my dogs going out and in all day. So we'll see!
