Another lunchtime at Shawell once again produced the goods. Lots of gulls were loafing on the steep banks and so I began harvesting colour-rings. Twenty in the notebook in the first half an hour was a great result, but then something created panic and the birds left the banks and huddled together in a noisy mass on the water. I scanned the flock and struck lucky when I spotted the long staying third-winter Kumlien's Gull. It is looking a fair bit paler than when I first saw it on December 28th 2019.
There was no sign of the third-winter Glaucous Gull whilst I was there, but a couple of Caspian Gulls were amongst the gulls, which were mainly Herring Gulls.
