Nothing is more discouraging to bird lovers, especially bluebird lovers, than repeatedly having to remove non-native House Sparrows’ nests from their bluebird nesting boxes. Now Duncraft introduces the new Sparrow Resistant Bird House that helps deter House Sparrows due to the shape of the nest box opening.

Non-native House Sparrows are a serious threat to native, cavity-dwelling birds. They not only take precious nesting spots, but are also aggressive and will attack native birds and destroy eggs and nestlings in order to take over a nesting box. For those maintaining nesting boxes for native birds, many methods have been used to deter House Sparrows. The Duncraft Sparrow Resistant House incorporates three advantages that may discourage these birds from occupying the house.

Researchers at the University of Kentucky have found that slot-shaped entry holes that span the front of a nesting box are very appealing to bluebirds, while House Sparrows tend to avoid them. It’s possible that sparrows dislike them because they let in too much light.

Besides the benefit of a slotted entry opening, Duncraft’s house is constructed of a high-impact plastic. According to the North American Bluebird Society, nest boxes made of similar material also appear to deter House Sparrows. These birds seem to prefer wooden houses. High impact and recycled plastics have the added bonus of lasting for years with virtually no sign of wear and tear.

Another advantage to the Duncraft house is that when House Sparrows raid a nest, they often trap and kill a parent bird inside as well as the nestlings. A larger entrance such as the slotted entrance on the Sparrow Resistant House may prevent House Sparrows from completely blocking the entry hole, allowing the victim to escape.

The Sparrow Resistant Bird House includes two landing perches and a hanger on the back for rear mounting. It also has a pre-drilled hole on the back and includes additional screws for a secure installation. The dimensions are 6 x 5 ½ x 9 ½ inches tall with an entry opening of 1 ¼ x 4 inches wide.

Founded in 1952 and located in Concord, New Hampshire, Duncraft’s objective is to bring the joy of backyard birding to wild bird lovers all across the country. Mike Dunn, owner and CEO is constantly inventing and searching for innovative ideas in bird feeding—giving bird lovers years of bird feeding enjoyment, success and satisfaction.
