觀察細節

A new high score for me too. By ones. Five adult, monster sized gull with black back. One looks like first winter, more like a checkerboard instead of solid back. The attached composite image shows most of the beach; only five GBBG's are visible. Reflecting on this 18 hours later, the one on far right is new, suggesting there were at least seven individuals around (i.e. down two from original six, then up a new one at the time the images were collected).
