Sabine's Gull- what a morning!

The four Black Terns flew off out of the estuary calling and were joined by a small gull with a dark hood. As it banked it had a lovely 'W' pattern on it's back - a superb adult Sabine's Gull. Wow! Other birds included 2 Arctic Skua, Knot and 2 Black tailed Godwit. What a morning!
