Best watch the video at full screen to see the pattern on the primaries although it is no where near as obvious as in the field. The bleaching is obvious when compared with the adult Herring Gull.
I had deliberately took a couple of hours off work this morning knowing there was most likely to be ice on the A5 Lagoons near Shawell. I have had a good track recorded of turning up good gulls when the ice comes.
Not surprisingly the lagoons were frozen. There was lots of gulls on the larger lagoon and the highlight was a Herring Gull ringed near Troms, Norway. J3613 was also at in 2013 and 2105. Its life-history also shows a visit to Vardo near the very top of Norway.
Three Caspian Gull were on the ice as well: 2 adults and a second-winter.
