Although blue jays appear to have blue feathers, they, in fact, aren’t blue; they are brown.<br /><br />If you were to take a blue jay’s feather and break it down, the pigment left would be brown.<br /><br />This is due to light scattering, which is when light passes through an object and is not reflected off of it.<br /><br />To put it simply, when light hits a blue jay feather, all the colors pass through except blue due to a special cell found in their feathers.<br /><br />This can also be seen when blue jays feathers become wet; they turn brown to their true natural color.
