“The Eastern Bluebird: Once Nearly Gone”

Eastern Bluebird

 

“The Eastern Bluebird: Once Nearly Gone” by Lesley the Bird Nerd.

It’s true we don’t see bluebirds nearly as often as robins, and I used to note well the rare instances I saw them in the yard growing up.

The film explains the blue color of the feathers in terms of selective light refraction, not pigment.
