That's where we come in. Bluebirds readily nest in man-made cavities. Many conscientious folks have erected bluebird trails to help this beautiful member of the Thrush family increase its numbers. A Bluebird trail can be simply one or two nest boxes in a spacious back yard or hundreds of boxes stretching for miles. If you live in a rural or suburban area and have a large lawn, you should have no trouble attracting these birds to your yard.
Trails are also easy to set up and maintain in city parks, cemeteries, and golf courses.
Now is the time to either clean out the bluebird boxes you already have or erect a new trail for the upcoming nesting season. In my yard, Bluebirds will begin nesting in April, but in some locations they can lay eggs as early as mid-March. To attract Bluebirds, you need a nest box specifically meant for them. Not just any bird house will do. These boxes are normally available at feed stores and garden centers or you can build your own.
