    This appears to be a group of mostly male Harlequin sea ducks. Males on the rocks, possibly a female in the water in the foreground. Identifying marks: A combination of the unique white patch/band in front of the eye (following contour of head), the white dot and comma shape around the ear region, and the rusty brown side body coloring.
