Rare Gulls

Over the past month we have seen a number of rarer gulls. At Arbroath a full adult Mediterranean Gull has been consorting with the similar, but much more common, Black-headed Gulls. The Mediterranean Gull is a fairly recent colonist to Britain; another with an expanding range. 
Close to home we found an adult Little Gull. These are found regularly on the east coast, as passage migrants in all sorts of plumage. However ours was decidedly inland.
Rare, however, was the Ring-billed Gull. This is a North American species. Occasionally they find themselves stranded on the wrong side of the Atlantic. Although the one pictured left is a first sighting of this bird for us it has been know to spend the summer in the same area where Common Gulls nest. I do not believe it was partnered with a Common Gull but it was certain looking good.
