Bluebird Birdhouses

It is not unusual for an avian enthusiast to have one or two favorite bird species. One of the most beloved species here in North America is the Bluebird; a species that has in recent decades seen significant decreases in their numbers. As a result, many bird lovers have taken it upon themselves to place Bluebird birdhouses throughout their property, in the hopes that these enclosures will help to rekindle their numbers. And while these particular enclosures might seem like any other birdhouse at first glance, the truth is they do have their own unique features.

Bluebird numbers have dwindled largely due to the introduction of two non-native bird species, the House Sparrow, and the European Starling. All three of these birds make their homes in similar locations, preferring cavities in trees and fence posts that are accessible only through a small opening. However, the fact that humans have cleared away a great deal of the trees that have been the traditional homes of all three species, the competition for the remaining spaces has had a considerable impact on the Bluebird. Sparrows and Starlings are by nature much more aggressive than is the Bluebird, and as such they are usually the victors in the fight for living quarters.

In order to level the playing field, Bluebird birdhouses are usually designed to swing the advantage to the Bluebird. The inside of these enclosures are generally kept between four and five square inches, depending on the type of Bluebird one is looking to attract. The access hole should be approximately one and a half inches in diameter, as anything larger can be used by the bigger, more aggressive Starling as well. Finally, perches should never be incorporated into those houses designed for Bluebirds. Number one, these birds do not require the perch in order to gain access to the enclosure. However, the more important issue is that a perch allows competing species and other predators to harass the occupying Bluebirds.

In most cases, these birdhouses are made from wood, with cedar and redwood being the preferred materials. Of course, these are not the only materials that can be used, as they can be found in plastic, clay, and even plywood varieties. However, whatever material is used, it is important that it contain no toxic substances that can adversely affect the birds living within. The outside of these birdhouses can be painted to match any other structures that might exist on a given property, but the insides are generally left in their natural state.

Finally, Bluebird birdhouses should be placed in a location that will ensure they are not disturbed by predators. Many people find that placing them atop a metal pole, away from any tree branches, is the ideal way to keep them safe from harm. The metal pole is often coated in grease to discourage any raccoons, badgers, cats, or other similar predators from climbing up to the level of the birdhouse. And if one chooses to set up more than one box on their property, they should be spaced at least 100 yards apart.
