	The highlight of the day was a Brünnich's Guillemot briefly off Hoy, Orkney Isles. The represents just the fourth summer record of this species in Britain, following singles on the Farne Islands, Northumberland in July 1977, Sumburgh Head, Shetland Isles in June-July 1989 and St Kilda, Western Isles during May-June 1992. Elsewhere, two Gull-billed Terns showed well during the evening at Bowling Green Marsh, Devon and in Lincolnshire a Bonaparte's Gull was discovered at Chowder Ness. Lingering rarities confirmed as still present comprised the House Finch in Devon at East Prawle, the territorial male Little Bittern in Somerset and the metal-ringed Blue-winged Teal in Cambridgeshire. Scarcities included Rose-coloured Starling (Cornwall), Purple Heron (Essex), Red-necked Phalarope (Orkney Isles), Great White Egret (Somerset), Green-winged Teal (Fife), Glaucous Gull (County Clare) and Caspian Gull (London).
