A possible second winter American herring gull was seen briefly today. It was vigourously bathing for about 5 minutes before flying off around midday. First seen by PK and seen by me and TC also. The Strikingly all dark tail and the remnants of a heavily barred rump was seen well. A large gull, longish bill, smoky underwing ,and the grey mantle colour being as pale or a shade paler than the close by argenteus herring gulls. I and some very expierienced gullers including gullers from America think this is a very good candidate for Smithsonianus.
Also today 3 adult med gulls and an adult yellow legged gull.
