You may notice a lot of properties in our area sporting bird boxes on poles. That's because we are on a North American bluebird trail: a series of bluebird boxes placed along a prescribed route meant to help with their population.
In areas where nest boxes have been put up, bluebird populations are increasing. Bluebirds build their nests in the shape of the box: square. When you get a sweet bluebird couple take up residence, you'll soon see their beautiful blue eggs, carefully tended by both male and female through hatching of their little ones.
