Adult Glaucous Gull, Shawell, December 29th 2018 |
Amongst thousands of Herring Gulls I located 14 Caspian Gulls including some handsome adults.
Whilst packing away to leave, I spotted a 'white-winger' amongst a flock of gulls that had come from the tipping area. It was the second-winter Glaucous Gull that I saw yesterday. The uneven primaries help to age it as a second-winter - a juvenile would have uniform primaries. Yesterday I saw that its eyes were becoming pale.
