Sunday 20th February 2011
	The highlight of the day was the reappearance of the Slaty-backed Gull in London at Rainham Marshes, where it commuted between Wennington Marshes and the adjacent landfill site until mid afternoon when it again departed to the east. Elsewhere around Britain lingering rarities comprised the Rufous Turtle Dove still in Oxfordshire, Pacific Diver in Cornwall, Northern Harriers in both Norfolk and the Western Isles, Long-billed Dowitcher in Dorset, Lesser Scaup in Gloucestershire, two Coues's Arctic Redpolls together in County Durham, and a Ross's Goose between Cumbria and Dumfries and Galloway. In Ireland the Thayer's Gull showed again in County Galway, the American Coot remained in County Mayo, as did the Bonaparte's Gull in County Cork, Blue-winged Teal in County Dublin and Small Canada Goose in County Sligo, where a new Bonaparte's Gull was seen briefly.
