Skomer Harrier

Hi Dave, I'm no expert (never seen a Pallid, & my Montagu's experience may as well count for nothing), but it certainly looks like one or the other purely because of the 4 primary tips showing, rather than 5 (assuming that is a concrete feature). I suspect you need to see it again to take it any further....but top marks for having the foresight to rattle off some images on such a brief sighting!
