The YlG from 24/10 on resv 1 at dusk. Closed wing appears to be fully adult, but Rob and Sonia Adderley saw the bird tonight with me and Rob reckons it is the same bird that he had in early October and that in flight it does show some brown on tertials, strangley absent at rest. Bill base is a strange peachy/pinky/orangey, but not quite yellow, with black subterminal band and only a tiny bit of pale at tip.
