Do that many birds take up residence in so many bird houses? I believe that females use these to house their young until they can be able to fly away from the nest and find food. A bird seems to come back to her nest each year and rebuilds her nest and lays her eggs under our roof. She, and her mate will fight off any intruders during the young one.s raising.

I know! We have "regulars" that return to our bird houses very year. It's like greeting old beloved friends. Blessings!
