Using Sparrow Spookers

Sparrow spookers refer to anything meant to scare away sparrows from perching on or entering a bluebird house. Using sparrow spookers on birdhouses is especially useful when a bluebird has already laid claim to a nesting box and has already laid an egg in the house.

It is possible to make a spooker using mono-filament fishing lines tied onto a ring and hang on top of the bird house. Ideally, the strings should swing around the entrance of the bluebird house. According to experts, sparrows hate flying through the lines and will therefore avoid houses that have them.

An alternative option is to hang several strips of a reflective material such as mylar film or even aluminum foil over the top of the bluebird house. When using this strategy, the strips ought to be long enough to brush against the roof of the house. Sparrows fear the strips and the sound they make while brushing over the box roof discourages them from taking up residence. However, since the strips may also scare away bluebirds, it is advisable to use this method only after a bluebird has claimed a box and laid its first eggs.

Why bluebirds need a sparrow resistant house

While all birds deserve protection, there are three primary reasons why bluebirds need extra protection from house sparrows:

• First, both groups of birds have a preference for nesting in natural as well as man-made cavities. However, sparrows fiercely out-compete bluebirds for nest boxes and will often evict them from their birdhouses. In short, when you put up a bird box in your yard, you are more than likely to attract house sparrows.

• House sparrows have a reputation for aggressiveness. In addition to forcefully evicting bluebirds from their houses, house sparrows also break their eggs and may even kill young and adult bluebirds.

• While bluebirds are North American natives, house sparrows are invasive and alien to the continent. In fact, house sparrows have only been in North American for about 169 years. Since bluebirds are native, they are protected under American law. Therefore, it is completely legal to remove sparrows or discriminate against sparrows from backyard nests with the intention of protecting Sialia.

The aggressive and over-competitive nature of house sparrows also means that bluebirds cannot comfortably nest close to a sparrow nest. Apart from dominating the competition for shelter, sparrows would also dominate the competition for food.

Parting Shot

According to conservationists, the population of bluebirds reduced drastically in the 20th century. So much that there were fears the bird would go extinct. Although the population of these North American native birds is on the rise again, more efforts are required to ensure that bluebirds thrive again.

Making bluebird house sparrow resistant is one way of contributing to the protection and conservation of these lovable and gentle birds.
