It is no different to building a scale model in its appreciation of the art.
Bluebirds and Tree Swallows may compete for nest boxes. For many years it has been suggested to the North American public that bluebirds are in deep trouble, their very survival in danger unless humans come to their rescue.
However, this simply isn't true. You may be surprised to learn that in fact: No bluebird species is or has ever been classified endangered or threatened. Eastern Bluebirds have the third highest numbers of the more than 60 species of native North American cavity-nesting land birds, even higher than Tree Swallows.
Statements that bluebirds used to be as common as robins are utter nonsense. However, continued public belief that bluebirds need preferential treatment has caused serious problems for Tree Swallows and those who enjoy them.
This is unfortunate because there are proven methods for reducing competition between bluebirds and Tree Swallows for nest boxes. You can enjoy both! There are three species of bluebirds, the Eastern, Western and Mountain. Like Tree Swallows, bluebirds depend on cavities for nesting but are unable to make their own.
And although Tree Swallows are significantly smaller than bluebirds in every major external body dimension but wing length, and are outweighed by bluebirds 30 grams to 20, where their ranges overlap swallows will actively compete with bluebirds for the scarce nesting cavities both species need, as Pat Grantham's photo below of Western Bluebirds and a Tree Swallow contesting a box in Montana dramatically illustrates.
For several decades now there has been a popular and highly publicized movement to erect nest boxes for bluebirds. Many people are devoted to "bringing the bluebird back" to supposed levels of former abundance, and some bluebird lovers become irritated when their boxes are occupied by any other species, especially Tree Swallows.
The complaint may be heard: They ganged up and drove my bluebirds away!
You may meet people, especially in Eastern Bluebird range, who tell you that encouraging Tree Swallows is wrong. Bluebirds and Tree Swallows are both native songbirds, equally worthy of care, consideration, and conservation, and Tree Swallows aren't preventing bluebirds from becoming abundant.
One species is not more "desirable" than the other. But unfortunately there is still resentment in some quarters when Tree Swallows compete for bluebird boxes, and a minority, hopefully very small, of bluebird hobbyists feels justified to destroy swallow nests and eggs they discover in their boxes.
This is both sad and unnecessary, to say nothing of immoral and illegal, since there are accepted management techniques that can reduce most strife between the species.
In the photo below a male Eastern Bluebird defends its box from an intruding Tree Swallow. Proper spacing of nest boxes for bluebirds: Much competition between Tree Swallows and bluebirds could be eliminated if bluebird hobbyists simply followed accepted box-spacing guidelines.
Since bluebirds defend large feeding territories around their nests they don't want to nest close to other bluebirds. Experts recommend that bluebird boxes should be spaced at least ' apart the length of a football fieldpreferably even farther. In contrast to bluebirds, Tree Swallows do not defend feeding territories, just a small area around their nest.
For this reason the recommended spacing for swallow boxes is only ' apart. This means many pairs of swallows can potentially nest within an area that just one pair of bluebirds would normally require. When bluebird boxes are spaced far apart the way they should be, a pair of bluebirds usually contends with just one pair of Tree Swallows, and in these contests the larger, stronger bluebirds normally win.
It's a myth that bluebirds are sweet, gentle and less aggressive than Tree Swallows. In fact, speaking of Eastern Bluebirds, Birds of North America states "Not only males but also females fight among themselves, and sometimes females wound and kill each other over access to nesting sites.
Swallows rely on screaming, persistent intrusions, dive-bombing, and pecks given on the fly-by. A bluebird's usual tactic is to wait at the box, making hostile displays, then dashing out to intercept the swallow, grappling with it and tumbling with it to the ground where the bluebird can peck the swallow and beat it with its wings, as the female Mountain Bluebird below is doing.

Because of development, a lot of their natural habitat is gone. You can help these birds survive and thrive by putting up a bird house, called a nestbox, that they can raise a family in.
