There are many different styles of birdhouse kits on the market today. The kits can be found in specialty birdhouses, such as those that are decorative as well as functional. They can also be designed for a particular species of birds, such as for bluebirds, since they are more particular than others. The dimensions of a bird house will either attract or deter different species of birds. There are some birds that prefer to nest in a deep environment and others that like to nest in a very shallow environment. There are also birds that like to barely be able to squeeze through the hole to the birdhouse and others that need a more open environment. The entrance to the house may also be a slit instead of a round hole because certain birds prefer that and it will deter others from entering.
Ideal Bluebird House Dimensions
Bluebirds are a more particular species of bird as far as their nesting environment goes. If the environment is not right then they will refuse to nest at all. Bluebirds will, in their natural environment, take the holes that were made by a woodpecker or a hole in a rotten trunk of a tree and make that into a nest. In the sprawling urban growth, this environment is being destroyed so that they are left without a place to nest. These birds are not able to build nests from scratch without a ‘container’ of sorts in which to place the nest materials.
The bluebird house dimensions are important to deter other birds from entering and to attract the bluebirds. The floor of the bluebird house should have the dimensions of five inches by five inches. This is a cozy size for the bluebirds who like to just be able to barely fit into the nesting area. The depth in the bluebird house dimensions is usually between six to ten inches. However, if sparrows are a problem in the environment where the birdhouse will be placed, the depth should be decreased to make it less attractive to the sparrows. Reducing the depth to about five inches is usually adequate to deter the sparrows, but it can be reduced to about three and a half inches if needed. Bluebird house dimensions of this shallow depth will still be used by bluebirds which do not mind a shallow nesting environment.
In addition to the bluebird house dimensions, the house should also have a drainage hole or holes at the bottom and have ventilation holes near the top for proper air flow. The house should also be set on a pole or post rather than in a tree so that predators are less able to get into it.
