观察细节

Winter plumage adult on Keyhaven Lagoon, mostly at rest but occasionally feeding. Intermediate in size between nearby BHGs and Little Gull. Large black spot behind eye. Black bill. Mantle clearly a shade darker than BHG. Short pastel pink legs. Grey hindneck apparent at certain angles. Black primary tips. At ~19:17 left the lagoon with most of the BHGs, at which point the diagnostic wing pattern was apparent - discrete, thin black edge to primaries with a white 'wedge' on outerwing. On reviewing digiscoped record shots, I did happen to get a shot showing the underside of the primaries.
