An early morning pottering around Uskmouth,...
... should have gone to Goldcliff.
Another troll round for Cetti's Warblers produced very little in the way of bycatch. It also meant I was at the wrong end of the reserve when the Black-winged Stilt arrived.
By the way, the bird looks like a male to me (very black and glossy on the mantle); head and neck plumage is very variable and, going on a conversation I half overheard, may have caused a Piccadilly/Bakerloo moment for some.
