Who Uses Those Fancy Copper Roof Birdhouses?

Bluebirds or tree swallows are likely to use a single entry home, with good chances of titmice, nuthatches or chickadees taking up residency in these, or even a triple-entry style. You’ll never find goldfinches, cardinals, robins or jays setting up house in one of these beauties though. Their preferences are hedges, shrubs and trees.
On a more stately scale, martins are likely to nest in a larger house with 8 or 12 entries, often referred to as 
Nobody will use any of these stunning birdhouses if you:
- never tend to it
- block the entries
- keep it indoors for decor… but over the years we’ve heard this and seen this, and it’s kind of sad because we’re bird freaks-but to each his own. Chocolate and vanilla, right?
One important thing to note if you’re planning to provide these houses specifically for birds to nest and raise their young: house sparrows! Once heard of as sparrow slums, the multi-entry houses are always inviting to killer house sparrows. And killer in its true meaning, (not like killer-awesome) house sparrows are very aggressive towards native songbirds. Due to a shortage of natural nest cavities, competition for nesting space is brutal… just ask any bluebird or martin landlord 🙁 If house sparrows are prevalent in your area, diligence is required to keep them at bay… regardless of any birdhouse you may offer.
