I've been plugging away at Acaster Airfield flash as often as I can, but the hoped-for scarce wader hasn't rocked up yet. This morning there were c50 Lapwings and a single Golden Plover in the field and absolutely zilch waders on the flash. A few gulls were loafing, including about 20 Lesser Black-backs, a couple of Herrings and, to my surprise, a stonking adult Caspian Gull! This really was a nice surprise. I have been checking for Yellow-legged Gulls which are a late summer feature in the area, but I wasn't expecting this.
