This is the perfect time of year to plan and prepare for the coming of the bluebirds. If you are serious about birding, you really should consider putting in a bluebird box or two. Several years ago my husband and his father started putting in blue bird houses following the trails that we had developed throughout our rural properties. Now every Spring we anxiously wait to see the first bluebird pair fly in and routinely check the boxes to watch for nestlings. Some years we’ve been successful, others we have not, but every year has been worthwhile!
Years ago bluebirds had many natural nesting cavities. They prefer open spaces at the edge of forests and would use old woodpecker nests, open knot holes in trees and other natural cavities or even rock crevices. But the introduction of the house sparrow and European starling changed all of that. These two invasive species not only took over those natural nesting cavities, but they began to prey on the bluebirds themselves, causing the bluebird population to dwindle.
Now, these beautiful birds are on a comeback thanks to many bird lovers who have put in and maintained man-made nest boxes. But the bluebirds are not the only ones to benefit. It is a joy for any bird watcher to hear the beautiful song of the bluebird and to watch the brilliant flash of blue as it flies by. As Henry David Thoreau said, “He carries the sky on his back.”
