Is there such thing as a blue headed crow?
== The American or common crow is black, but has iridescent plumage that can appear to be another color (like blue) if the lighting correct. It's an optical effect, but can present some remarkable variations on the theme. We've probably seen the phenomenon in insects (beetles, butterflies) or even on other birds. == We have a black crow that has been showing up at our bird feeder for a week now. When it spreads it's wings there is a rich blue color each time. We haven't seen any other color to date. We will keep watching. We are located in the country outside Seattle. Is this still an optical effect? == Certainly if an observer sees "blue" on a crow, he sees blue. No doubt. A lot of observers report this. And they are 100% correct in what they see. Even the camera catches the colors. What is still the same is that the plumage is black, but the observer is experiencing an optical effect - iridescence. Light does some funny things when it wants to. Few of us have not seen colors on a soap bubble when the light is "right" and we are looking at them. But it is a "trick of the light" to see colors there. Oh, they're there all right, but not because the bubble is any of the colors we see on it. Light is phase shifted, diffracted or undergoes interference. Or a combination of them. Believe your eyes, but believe your cortex. We see blue (or other colors) but not because the object under observation is really that color. Certainly an argument could be made to say a crow isblue if that is desired. But the color is a "temporary" one; it disappears under different viewing conditions. The black is constant. Need a link to the Wikipedia article on iridencence? You got it. The article is short and to the point. The pictures are good, too. Answer i think azure jay
