This old favorite bluebird birdhouse is popular because it discourages cats and other predators. Since the bottom tapers, less nesting material is needed. The front opens easily for observation and cleaning. Mount this box high on a post so that potential occupants can be easily observed from a distance. The new oval entrance hole makes it easy for the mother to lean inside to feed her babies. See our Eastern Bluebird house and Western Bluebird house.
