Wren Bird Houses

Whether or not you choose a decorate birdhouse or a hanging wren bird house really doesn't matter. I don't think the birds really care. They're more concerned about getting in out of the weather. The bird houses offer them a place to rest, build a nest, or shelter them from the wind, rain, heat or cold.
Having bird houses also offer you the opportunity to learn more about the bird. Their habits, nesting routines and rituals, mating practices, their singing etc. This is a good pastime/hobby for you, your children and/or grandchildren.
