Monday is a time to focus on readers' questions for better birding, and this week, Gwen from Indiana asks...
"I want my husband to build me a new bird house for our backyard wrens, but he needs to know how to build it. What size should the house be?"
Birds aren't always particular about the size of the houses they will nest in, but wrens - both the house wrens and Carolina wrens you may have in Indiana - will enjoy a house with an interior base of 4x4 inches, an interior height of 6-8 inches and an entrance positioned 4-6 inches above the floor. The entrance hole should be 1 1/4 to 1 1/2 inches wide. So long as you are close to these dimensions, the new real estate should be very interesting to your wrens!
