Western bluebirds are known to go house shopping. The male shows his mate several nest sites, but the female is the one who makes the choice. She then places a small twig in the cavity or nestbox to stake her claim.
Birds also use the boxes as a roosting site in cold weather. So if you have a nestbox, make sure it's cleaned out and ready for spring.
