Cormorants!

As I cleared the heavy frost off the car early this morning, I heard the familiar call of Bewick Swans flying out of the ARC over me to feed at Horses Bones Farm.  
Early morning at Cooks Pool, the Whoopers Swans roosting with the Mutes

 As I arrived at the sea watching hide wave after wave of Cormorants were flying past out of Rye Bay round The point into Lade Bay. The image above does not begin to show the numbers that swept past. I was trying to count them in blocks of 10 and believe a minimum of 9,000 birds were involved.
After that spectacle I wandered down to The Patch which was very quiet, probably because the boil was virtually non existent. Offshore plenty of Auks were tooing and froing, with a few Red-throated Divers and Gannets also 23 Brent Geese flew East.

Razorbills and a Guillemot off the fishing boats this afternoon
MH joined me at the fishing boats this afternoon for a bitterly cold and fairly brief sea watch, which once again saw 100s of Razorbills and Guillemots tooing and froing and littering the sea while chasing Sprats, c50 Great-crested Grebes were feeding along with the omnipresent hordes of Cormorants, also 5 Turnstone on the beach and Grey Seal off shore.
Next stop the RSPB visitor centre for a warm up, where a Norwegian ringed Great Black-backed Gull JU850 was roosting. Details below.

1w Caspian Gull
While I was in the visitor centre I saw a 1w Caspian Gull drop in front of Firth Hide, I quickly made my way to the hide, where fortunately the bird was still present and showing well.
