MBP: Here's someone we haven't seen in awhile, the blue jay.

My field guide has the same claim: "Feathers don't have blue pigment; refracted sunlight casts blue light." I suppose that could be tested be getting a blue jay feather and putting it in some other light than sunlight and seeing whether or not the color changes. But I do notice that blue jays still look the same to me even on cloudy days when there's no direct sunlight.
