We have four birdhouses, also known as nestboxes, in our backyard. Two of them are occupied this spring.

One nest box that has been the home of an Oak Titmouse family in past years is occupied by Chestnut-backed Chickadees this year. The other nestbox appears to provide a home for Wrens. The Chickadees are very active flying in and out of the nest box several times a day. I’ve seen the Wrens occasionally.
