Natural enemies pose the greatest hazard to birds using man-made houses.
Iron poles used for mounts or a sheet metal guard encircling trees or wooden poles will help protect birds from cats and squirrels. Houses suspended from wires beyond the jumping range of these predators can be effective. Ubiquitous English sparrows and starlings can prove exasperating to those seeking to attract native species to bird houses. Only by persistent harassment can these pests be eliminated. Often sparrows can be trapped inside the houses during the night.
