Birds such as Tree Swallows and bluebirds will nest closely to one another, although conspecifics will be driven away. Pairing boxes has the advantage of allowing more birds of both species to coexist peacefully within the same habitat. This will prevent the fledglings from flying into the road when leaving the nest. 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. View construction plans for predator guards. View plans on how to hang nest boxes. 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.
