Thus, natural cavities are sparsely distributed, particularly in young forests, in areas with low woodpecker populations, and in areas where dead trees have been cut down. In these types of areas, cavity_nesting birds often have difficulty finding nesting and roosting sites and will readily use suitable birdhouses. Properly constructed birdhouses provide nesting and roosting birds the same protection as natural cavities in trees. This includes protection from wind, rain, cold, and nest predators (red squirrels, weasels, ravens, crows, jays, etc.).
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.
