CONCORD, N.H. — Like many nesting birds, bluebirds are susceptible to losing their nesting box to larger, invasive cavity nesters, including House Sparrows and starlings. However, there are natural ways to discourage these unwelcome cavity nesters. According to Sialis.org, “Boxes should be properly designed (with correct hole size) for small cavity nesters you want to attract, with a door or roof that opens for monitoring and cleaning, and be solidly constructed so they will keep rain and predators out, and last for years.”

Bluebird house specialist and creator of the Gilwood house Steve Gilbertson, spent years on his bluebird trail testing bluebird houses to see which one they prefer. He observed bluebirds paid, “a lot of attention to these four elements [entry hole, nesting depth, cavity size and ambient light level] when selecting a nestbox.” Originally designed by Gilbertson, the Gilwood Bluebird House uses several of these features to deter larger birds. The 3/8 inch metal wire rod stretches across the entrance to reduce the entry hole to 1-1/2 inches to keep out larger birds, while letting in the desirable amount of ambient light and ventilation to attract nesting bluebirds. Since starlings and other invasive nesters prefer larger nesting cavities, the Gilwood’s proven 4-1/4 x 3-1/2 inch flooring provides bluebirds with additional, and necessary, protection.

After years of trail research, “[Dick Peterson and myself] discovered that the birds, when given the choice, were more inclined to choose a nest box with a floor size of between fourteen and sixteen square inches. A floor size in this range would serve another purpose: it deters the European Starling, a competitor species that prefers a much larger cavity.”

Gilbertson continued, “The Peterson nestbox has a nesting area of around fourteen square inches [at nest level], and starlings almost never attempt to nest in that box! even though they can squeeze through the Peterson oval entry.” Although Steve Gilbertson is now retired, his legacy of proven bluebird house designs continues to live on at Duncraft, where the durable Bird-Safe® Peterson Eco Bluebird House is now available in new colors: classic Duncraft green and brown.

“It is our responsibility to keep the birds safe by designing and building a nestbox that is tight and dry, won’t overheat and is easy to monitor,” noted Steve Gilbertson, who is recognized for his vital contributions to bluebird recovery. Two new Duncraft bluebird houses pay heed to Gilbertson’s insight with a double layer roof on the Bluebird Trail House & Pole and Gilwood Bluebird Slotbox & Pole to better reflect the hot sun and prevent nestlings from overheating.
