Not literally, just the location in which it was found!
I found this adult Mediterranean Gull at Dogsthorpe rubbish tip this morning in amongst a group of Black-headed Gulls. A lovely bird that is practically in full summer plumage and it was present along with a 2nd winter Med Gull and a Yellow-legged Gull which looked like a 3rd winter bird to me, but I am no expert. There were no signs of any white wingers, but the majority of the larger gulls were seen to be present on the non-accessible side of the tip, so yesterdays Iceland Gull could have been there.
The above photos show the birds` position in the group and then I have cropped the pictures to show the Med Gull a bit closer. It is the bird that is continuously in the centre of frame.
