Position the house so its opening does not face into direct sunlight or prevailing winds. Full or partial shade will help keep the house cooler, and a more protected location will be safer. If necessary, a longer overhang above the entrance can also help provide shade and shelter. Angle the house so rain cannot easily run into the opening or through ventilation holes. Some bird house models include an angled face to ease water runoff, and a larger roof overhang can also help keep the interior of the house dry. The house could also be positioned in a more sheltered area, such as underneath the eaves of a roof or against the trunk of a large, full tree that will help protect the bird house.
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.
