The Eastern Bluebird (Sialia sialis) is a charming and iconic bird species that inhabits a substantial portion of North America. Renowned for its vibrant plumage, it gifts an unmistakable cheerfulness to those fortunate enough to observe it.
Bluebirds are relatively small, measuring just 6 to 8 inches in length. They are characterized by brilliant blue plumage on the upper parts, a rusty-orange breast, and a white belly. These colors, which are more vivid in males, make them easily distinguishable in the wild. Their appearance is a testament to nature’s artistry, and their presence is a source of joy for many, professional birdwatchers and casual observers alike.
Beyond their attractive looks, Eastern Bluebirds are also known for their sweet, melodious songs. Their musical trills and warbles grace the air, filling it with their enchanting tunes. This musical prowess, combined with their striking appearance, makes them a favorite among birdwatchers all across America.
When it comes time to raise a family, Eastern Bluebirds are cavity nesters. They typically build their nests in natural or artificial cavities, like old woodpecker holes or specially designed birdhouses. These nests serve as safe havens for their delicate blue eggs and young chicks. The birds are known to be quite adaptable when it comes to their nesting preferences, and this adaptability has allowed them to thrive in various environments, from open fields to woodland edges. Bluebirds generally mate for life, raising two and sometimes three broods per year.
While they primarily feed on insects, Bluebirds have a varied diet. They also enjoy fruits, particularly during the winter months when insects are scarce. This dietary flexibility helps them survive the changing seasons and adapt to the unique challenges posed by their particular habitat.
If you live in the city and bluebirds are on your watch list, you might have some luck glimpsing them in suburban parks, larger yards and golf courses. For the most part though, they inhabit rural countryside. Grassy fields and meadows, nature reserves, fence lines, forest edges and country roads are all prime bluebird-watching features.
Want to attract bluebirds to your yard? Provide them with food, shelter and water.
Shelter: Bluebirds are cavity nesters and readily use nesting boxes. Place well-constructed bluebird houses with the correct dimensions (1.5-inch entrance hole) and proper ventilation in open areas with some nearby trees or shrubs. Ensure the boxes are mounted at the correct height (around six feet above the ground) and face them away from prevailing winds.
Food: Because bluebirds eat mostly insects, plant native flowering plants to attract their preferred bugs. Avoid the use of pesticides, and supplement their insect diet with suet and mealworms once the weather turns chilly.
Water: Provide a bird bath or a shallow water source for bluebirds to drink and bathe. Clean, fresh water is essential for their health, so be sure to thoroughly clean and sanitize at least every three days.
Eastern Bluebird populations have faced challenges over the years due to habitat loss and competition from invasive species. This has prompted conservation efforts by organizations and individuals all across the US. The creation of bluebird trails, monitoring and maintaining birdhouses, and raising awareness about these birds’ needs have all played pivotal roles in ensuring Bluebirds’ survival.
The Eastern Bluebird’s story is a testament to the profound impact that individuals, communities, and conservation organizations can have in preserving the natural world. It is a reminder of the importance of cherishing and protecting the diverse wildlife that graces our planet.
