Dear all, To add to Harvey Mudd's extensive discussion of iris color: Others may have already noted the video on larger gulls describing the individual variation in iris color of western hemisphere kelp gull. One kelp gull is shown having a pale iris on one side of its head, and a dark iris on the other!
