This is another of my sightings from December, certainly the best view I had all year of a Mediterranean gull (Larus melanocephalus).

As is usually the case, it was with a large flock of Black-headed gulls, searching the grassy playing fields of a Cardiff park for worms and other invertebrates. These gull flocks can be quite skittish but, as there were no dogs being walked off lead on my side of the park, this lot were content to continue their search while I sat on a park bench watching and taking lots of photographs.
