Not the best image of an Eastern Bluebird, this photograph does capture the intensity of the bird’s wings, rump, and tail. We found several bluebirds along a Northfield pond on 15 October 2018. The blue of bluebirds depends on light refraction, not on pigmentation. Air pockets and melanin in the feathers scatter blue light and absorb other wavelengths (Birdnote.com).
