    This isn’t that pedantic paint shit. The tweet did a bad job of explaining

    Blue Jays are blue because of structural coloration rather than pigmentation, like how peacock tails or butterfly wings work. While the actual pigmentation on a Blue Jay’s wings is brown, the light bending caused by the tiny structures within their feathers makes them blue. Pretty neat!
