I arrived in Cardigan very early this morning and all the visible gulls were on a nearby roof-top. I am not very familiar with this species and so it was handy to see its size in comparison with Herring and Black-headed Gulls.
In this digi-pic it is the bird on the far left.
It then flew across the river to the slip-way on the southern side.
After a while it foraged along the shore, often close to a Common Sandiper.
I had some bread with me and that soon got the bird flying around before it settled on one of the posts in the river.
