Those who love the bluebird have begun a massive effort to save it through the erection of thousands of nesting boxes appropriate for this species and predator- and competitor-proof. And the bluebird is beginning to reappear in areas where these bluebird houses are established.
Providing bluebird houses has long been a favorite pastime in North America. Bluebirds are loved for their beautiful blue coloring, as well as, their gentle disposition and pleasing voice. The bluebird is the symbol of love and happiness in many of our songs.
Once a common bird, the bluebird was numerous even in urban residential areas, but it has seen a decline in numbers, with the Eastern Bluebird losing up to 90 percent of its population. A number of factors, such as insecticides, the destruction of their habitats, predators, and competition from other birds have contributed to this decline. The destruction of some of their food supply, such as the wild holly berries used in Christmas decorations, has also been a factor.
We can assist in the return of this lovely bird by providing suitable habitats, winter shelter, and food supplies. Plants that bear berries throughout the winter (bittersweet, hackberry, dogwood, American holly, privet, bayberry, sumac, and others) will provide food for not only bluebirds but many other species. Winter roost boxes provide shelter in the coldest season for many birds. In areas where bluebirds find sufficient food, they may stay all year, but a roost box will allow them warmth on cold nights. And specially designed bluebird houses, with predator guards on the entrance to keep out squirrels, raccoons, and competing birds, will give the bluebird a safe place to live and rear its young. Nests of sparrows and other competitors must be cleaned out of the bluebird house on a regular basis.
