Farmoor Med Gulls in late afternoon

Arrived 16:40, so far too late for any hope of raptor watching. 1 Rockit, 2 Mipit and perhaps 20 Pied Wags plus 1 Ringed Plover in the SE of F1. Enormous gull roost this evening and gusting gale force WSW, so concentrated on F1 only. Common Gull totalled at least 16 birds, with 1 1stW, a few adult and the remaining being 2ndW plumage. Yellow-legged Gulls of all ages but not really counted as concentrating on searching through Black-headed for Med Gulls and better(?) Med success with 1 1stW (no real mask as yet) on water before leaving F1 for F2 at 17:25 and then another 1stW did similar at 18:15 - seen only in more distant flight. Must assume two birds as no return of gulls from F2 to f1 noted during watch. Who knows what could be seen here if there was a wind proof shelter to observe from.....
