Be sure young birds will be able to leave the nest. Roughen the inside of the nest box below the entrance hole or attach a sheet of 1ǚ_inch galvanized wire mesh, so fledging young can climb out easily. Provide woodpeckers, waterfowl, and owls with nest material. Many cavity_nesting birds will add their own nest material, but the woodpeckers, waterfowl and owls prefer nest boxes with 2ι inches of dry sawdust or woodchips in the bottom.
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.
