When certain birds (not owls) look out at you from their left eye, they can’t see you with their right eye on the other side of its head. So what do birds with eyes on both sides of the head actually see? Two different scenes? Or some sort of panorama distillation?
Color abnormalities don’t seem to be very unusual in juncos. There is a junco who sings outside my work building who has white splotches all over him! None of the juncos we’ve caught have been that extreme, but we have found a few with unusual spots of color on them.
We band it with the uniquely numbered US Fish & Wildlife band. This is the first priority because once the bird has this on, we can identify it later even if it escapes. Then we add the three colored leg bands so that we can identify it later even from a distance.
