Whichever method you choose to erect your boxes, be sure your box is secure enough to withstand high winds and severe weather. The best way to erect small nest boxes is on free-standing metal poles or PVC pipes. Many predators find poles difficult to climb. Poles can also be easily equipped with a predator guard.

In a pinch, small nest boxes can be mounted on fence posts or trees. If you wish to attach a box to a living tree, do not use nails. Rather, slip a strand of galvanized wire through the vent holes and attach a bungee cord to both ends. Stretch the bungee cord around the tree, preferably over a limb. Remember however, that hanging boxes from trees provides an easy route for predators to reach the box.
