Clean the house seasonally or whenever a family of birds vacates the premises: Remove all nesting debris and rinse the house with a sanitizing solution of one part bleach and nine parts water. Rinse the house again with clear water, and allow it to air dry thoroughly before storing it for the winter or repositioning it for new tenants. Nesting birds face many different hazards, but there are easy ways to make any bird house design safer and more attractive to bird families. Building a bird house may seem like an easy project, but there is much more to an attractive, bird_friendly house than a wooden box with an entrance hole. Before you build a bird house, you need to understand what nesting birds need and how best to meet those needs with the house you construct.
Position the bird house far enough away from brush so predators cannot stage an ambush, but close enough to plants so parent birds can easily scout the area. Five to eight feet of distance is sufficient for most bird houses. Similarly, keep bird houses away from popular feeding areas to prevent territorial conflicts between feeding birds and nesting parents. Choose natural colors so the bird house will blend into the surroundings: Browns and dark shades of green are the most suitable choices and will be the most attractive to birds. If desired, decorate the house with natural materials to keep it concealed but still an ornamental focal point in the yard.
