    Two together on south side which I had good views of through my scope for a couple of minutes as they moved in and out of view between rocks. I moved closer for a better look but they vanished either walked around the back of the little island or flew off.

    Later I had superb views of a definitive bird (see definitive wing coverts) on the north shore but only for a couple of minutes before the bird quickly moved west along the shore and around a corner.
