|Caspian Gull, First-Winter, Cotesbach LF site, September 2015|
these are much less distinct than those of the first-winter Yellow-egged Gulls that are present at the moment. Its coverts are plain brown with fine pale edges and the inner greater coverts are solid brown with faint buff edges. Its tertials had white thumb nail like tips, which again is different to YLG's of a similar age. Its head was white with no sign of a dark mask.
Below is a similar looking gull from December 2014.
|Polish Ringed Caspian Gull (16P4) Shawell A5 Lagoons, December 2014|
Another juvenile gull was causing quite a stir, as its white primaries seemed to scare the other gulls. Its a good job its not a young Herring Gull, as it might be mistaken for a 'white-winger' as an adult.
