I may need to tread lightly here. I expect this could be a touchy subject, but I believe something needs to be said. Maybe there will be counterpoints, or maybe there will be a general agreement. Maybe I will change your mind, or maybe you will change mine. Who knows? There’s really only one way to find out, and that is to just put it out there for discussion. In this article I am going to make the case against building and hanging nesting boxes in public nature areas. Let’s see where this goes.
The nesting boxes were hung by the river with care. In hopes that Bluebirds and Wood Ducks soon would be there…
Bird Boxes, as their name implies, are boxes constructed by people for use by cavity nesting birds. They are typically built of wood, and come in a variety of sizes depending upon the species of bird being accommodated. A hole is made in one side to allow access the the interior. The idea is to model a natural cavity such as a crevice, knothole, or woodpecker hole.
Nesting boxes can be hung on trees or mounted on poles. In some situations bird boxes can be vulnerable to predators. To guard against this, boxes are often fitted with additional protection in the form of baffles meant to exclude climbing animals.
Nesting boxes are certainly always hung with the best intentions in mind. Building and mounting these kinds of boxes is a common project for those who are outdoor and nature oriented. Beginning naturalists often get their introduction to the natural world with projects involving nesting boxes.
The benefits of bird boxes are thought to be many. The idea is to provide safe and relatively predator proof places for birds (and sometimes other animals) to nest and raise their young. What could be better than creating a little haven for wild animals to raise their offspring? Surely this is a noble pursuit.
In places where natural features are lacking, nesting boxes may actually enhance the environment by providing refuge and promoting wildlife diversity. In other places, however, they are likely superfluous and unnecessary. But just being unnecessary is not the real issue here.
So, what IS the real problem with nesting boxes? Well, simply stated, bird boxes are intrusive and unnatural in appearance and therefore they visually distract and detract from any natural environment they are set in. Further, when fitted with a predator deterring baffles nesting boxes can create auditory problems as well. The baffles clank against the mounting posts like clappers on a bell. This adds an unnatural metallic sound to the environment in places already intruded on by far too many man-made noises.
The worse case—and unfortunately very common case—is when installed nesting boxes are allowed to fall into disrepair. Bird boxes, once mounted, are often forgotten about. The ravages of time take their toll and the boxes become dilapidated. When allowed to fall into disrepair nesting boxes no longer benefit wildlife. In this condition they are little more than eyesores at best. At worst, nesting boxes that fall to the ground become litter and refuse that must be cleaned up and removed from our wild areas. I’ve spent the last couple of years collecting photographs to help make my point.
So, how do you salvage the benefits of nesting boxes while eliminating the problems? There may be a couple of things that can be done. Here are two suggestions that might help improve the situation.
The first option would be to simply design, build, and hang less intrusive nesting boxes. Boxes could be built in organic shapes with materials textured and colored to help them blend in with the surroundings. Locating nesting boxes in places not easily seen from well traveled paths would benefit both the human sightseers and nest box occupants alike.
The second part of the solution would be taking long term responsibility for bird boxes placed in the wild. My contention is that when someone sponsors the creation or mounting of these boxes, they should also be prepared to take ownership of their lifetime care and maintenance. Boxes that are allowed to become ramshackled do not benefit wildlife and they do not benefit the public. They are, in a very real way, pollution and eyesores. Let’s consider carefully before installing more.
