Stinking Goosefoot on the Butts.
6 Eider heading north was a bit of a surprise with the only other species on the move being a small handful of Sandwich Terns. On site the first Reed Warbler of the autumn, a moulting adult Blackcap plus the 2 loitering Nightingale heard duetting.
This well marked Metzneria metzneriella is not a species featured on the blog before. It's one of those that the books say is 'common' but it is no where near as common these days here as in the past although paler examples may be being confused with one of its commoner congeners.
Ringing: 6 Linnet, 2 Wood Pigeon, 2 Wren, 1 Blackcap, 1 Dunnock, 1 Great Tit, 1 House Sparrow, 1 Lesser Whitethroat, 1 Magpie, 1 Reed Warbler.
