When it comes to positioning a nest box for bluebirds, it is important to consider the direction and orientation. One of the key recommendations is to have the entrance hole facing east. This is because bluebirds prefer their nest boxes to receive morning sunlight, which helps to warm up the box and provide a comfortable environment for the birds.
By facing east, the nest box will receive the warm rays of the rising sun, which can be beneficial for the eggs and nestlings inside. This orientation also helps to protect the box from the hottest afternoon sun, which can sometimes be too intense and cause overheating.
In addition to the east-facing direction, it is also important to position the nest box towards open habitat. Bluebirds prefer open areas with scattered trees or low vegetation, as it provides them with suitable foraging opportunities and reduces the risk of predators sneaking up on the nest. By positioning the box towards open habitat, you are creating a more suitable environment for the bluebirds.
To further enhance the chances of bluebird occupancy and reduce competition from other cavity-nesting birds, such as Tree Swallows, it is recommended to pair nest boxes about 15-20 feet apart. This spacing helps to create a sense of territoriality for the bluebirds, as they are less likely to tolerate neighboring nests too close to their own. Additionally, by spacing the pairs of nest boxes about 300 feet apart, you are providing enough distance for separate bluebird families to establish and thrive without interference.
I have personally experienced the benefits of these positioning recommendations. In my backyard, I installed a bluebird nest box facing east towards an open meadow. The box receives the beautiful morning sunlight, and I have been fortunate enough to witness several successful bluebird broods over the years. By pairing the nest boxes with appropriate spacing, I have noticed a decrease in competition from other cavity-nesting birds, allowing the bluebirds to have their own territories and raise their young without disturbance.
When positioning a nest box for bluebirds, it is best to face the entrance hole towards the east to receive the morning sunlight. Additionally, positioning the box towards open habitat and spacing them appropriately can further increase the chances of bluebird occupancy and reduce competition from other cavity-nesting birds. These recommendations have been proven effective in creating a suitable environment for bluebirds and maximizing their chances of successful breeding.
