Thanks for your comments, Gin. I got a very good look at the Carolina wren at the feeder this morning. So glad it’s not a house wren. I’m afraid to put up another box. So far the one I put up is good for bluebirds. I don’t have any birds here disturbing them in any way. Right now all the birds are compatible. They move when the blue jay arrives and return when it leaves.
