Blue Bird Houses
Blue birds can not make their own house. During the time of brooding they pick up the holes as nest that are generally drilled by wood peckers or any natural cavity inside the tree trunk or the branches. But while selecting their nest they are very finicky about the plan or design of the holes. They are often the victims of predators or birds like house sparrow or starlings that either kill or drive them out to occupy the blue bird houses.
Within the past 60 years there has been 90% decrease in the population of the birds. Since the bird mainly resides in the open farm lands, the extensive usage of pesticides has lowered down the population of the bird to a great extent. The incidence of severe winters has increased the mortality rate of the birds. The two other significant causes for the decrease in the number of birds is that the low availability of cavity trees. The growth of well trimmed orchards has lowered the possibility of finding a good cavity nest for the birds. The bird also experiences a steep competition with other birds like sparrows and starlings in the search of protective nests.
While finding a nest the blue birds make sure of safety and the comfort. So, to attract blue birds your blue bird houses must be placed in some definite locations that would ensure security to the birds. The following are some probable locations where you can place the houses for blue birds.
Locations for Blue Bird Houses:
- The natural habitat of the bird consists of open woodlands, farm lands and places that have ample old trees. So, place the blue bird house in some rural or suburban locations.
- The birds mainly feed upon insects. They swoop down into the ground and pick up insects. In order to facilitate them with good hunting spaces the house must be hung to a tree that is surrounded by low branched bushes and the soil to be scattered with leaves. The presence of a post would be easier for the bird to hunt.
- Find a place that has sparse vegetation. Dense vegetation may not be convenient for the bird to scan the ground for insects.
- Hang the houses of the blue birds to a post or a tree of a height of about 100 meters above the ground. The nest must also be one fourth mile far from the regions that are generally dominated by the sparrows.
- Be careful of the space between one blue bird house and the other. During the breeding season the blue birds get territorial in nature.Research tells that blue birds generally do not build nest with hundred yards of another.
- To protect the blue bird from the sparrows you may hang up pair boxes with 5 to 15 feet apart. The sparrow would build nest in one while the other can be taken over by the blue birds.
To help them to build their nest you may provide the birds with nesting materials like soft grass and fragrant pine needles as they are preferred by the nesting blue birds.
