Eastern Bluebird (Sialia sialis) - Baby Bluebirds

The vibrant blue color in bluebirds is not due to pigment but is a result of light scattering by the structure of their feathers, similar to the way the sky appears blue. This structural coloration gives bluebirds their brilliant hues.

Bluebirds prefer open woodlands, meadows, and areas with scattered trees, which provide nesting sites and perches for hunting insects. They've also adapted well to human-altered environments like orchards and suburban areas where nest boxes are provided.
