We’ve given up on the old nest box, which produced year after year of failure. After removing it, we decided to add a variety of nest boxes to the yard and see what works best for the birds. This little wren is testing one of the new boxes.
I believe this is a house wren. Please comment if you can correct or confirm my identification!
He started the nest Sunday evening, worked through the day on Monday, and has spent most of this morning singing.
The nest looks wonderful, to me, and I hope he finds a mate who agrees.
