55. Provide nest boxes and platforms, and monitor them responsibly.

For hundreds, perhaps thousands, of years, Americans have been providing housing for wild birds. The earliest Americans provided hollowed-out gourds for Purple Martins. The Purple Martin Conservation Association notes that “documents from the 18th and 19th centuries suggest that these early Americans attracted martins to their villages because they functioned like scarecrows, chasing crows away from their corn patches, and vultures away from their meats and hides hung out to dry. The mutually-beneficial relationship established then, still exists today.”

Unfortunately, improperly designed or situated birdhouses can cause eggs or nestlings to die from excessive heat or cold or to drown. When they are not monitored and maintained properly, debilitating and even lethal parasites can flourish. And birdhouses designed by well-meaning but uninformed people can be open invitations to House Sparrows and European Starlings, both of which are threats to native American birds and do not need housing subsidies. With just a few precautions, however, providing nest boxes or platforms for birds can be a wonderful hobby.

House Sparrows

The first step is to decide what species you want to attract and then learn about its nesting requirements. The Cornell Lab’s Birdhouse Network now Nestwatch can give you a lot of helpful hints. Organizations such as the North American Bluebird Society, Project Loon Watch, or Purple Martin Conservation Association focus on particular species and can provide state-of-the-art information on monitoring techniques and precautions, hole size and shape, house design, and potential predators.

Keep in mind a few basic precautions:
