Blue Jay
One of our favorite birds that come to our feeder is the Blue Jay. The blue colors are magnificent! Today we learned a little something special about those magnificent blue feathers...
"Eastern Bluebirds, Blue Jays and some other local birds have what appear to be blue feathers. However, there are no blue pigments in bird feathers. The appearance of blue is brought about by the particular structure of the feathers. That structure allows all the different colors of visible light (all the colors of the rainbow) to enter the feather but only blue colors are reflected back out. All the other colors are absorbed by the feather and can't be seen. So, a Blue Jay appears to be blue not because of blue pigments but by selective reflection of light" -Web.Colby.Edu
