Single Great-northern Divers south plus another in off then up river plus an adult Yellow-legged Gull are this mornings highlights. Also worth a mention 23 Red-throated Diver north plus 8 Brent & a Red-throat south. Been loitering around car parks trying to note rings on seagull legs recently and it is extremely noticeable that there is a dearth of first-winter Black-headed Gulls again this winter.
