The American continent is home to a multitude of blue bird species. From seed dispersal to insect population control, these little passerines play a huge role in the ecosystem. Despite their small size, these birds are incredibly strong and capable of long journeys. Some of these birds even migrate to and from the northern hemisphere in order to avoid harsh winter temperatures. Luckily, these bluebirds aren’t endangered and are thriving in their habitats.
Generally, the color blue in birds is due to the scattering of light, much like the way a prism works. When a cardinal’s feather is ground up, it will show a variety of colors. But, when it comes to bluebirds, their feathers are iridescent and appear to be pure sky-blue.
Eastern Bluebirds are skilled fliers with incredible vision; they can see an insect on the ground from up to 60 feet away! They build small cup-like nests inside old woodpecker holes. They communicate with their flocks using vocalizations and use calls to warn predators of their presence. They are also frequent visitors to backyard bird feeders and prefer sunflower seeds, white proso millet, and nyjer thistle.
If you are looking to attract Eastern Bluebirds to your backyard, try placing your feeders near some shrubbery to provide foraging and nesting locations. Listen for their liquid-sounding warbling song which consists of several notes that are repeated in a row.
The male Lazuli Bunting is deep bluish on head and neck, with chestnut wing bars. The female is a duller cinnamon-brown. This exotic-looking bird forages in low areas of bushes and trees for insects, especially spiders and caterpillars. You’ll most likely see them in the Western United States. If you are able to lure them to your backyard bird feeders, they will most likely enjoy nyjer thistle seed.
