Green Sandpiper (Tringa ochropus)

I spotted this one on my way to Slimbridge, it is a Green Sandpiper, I am not 100% sure of that, but I think it is. I have a good clean image, I am pleased.

Red-breasted Merganser (Mergus serrator)

These handsome diving ducks belong to the sawbill family, so called because of their long, serrated bills, used for catching fish. Their diet of fish such as salmon and trout has brought them into conflict with game fishermen. At home on both fresh- and saltwater, red-breasted mergansers are most commonly seen around the UK's coastline in winter. They are gregarious, forming flocks of several hundred in the autumn. (RSPB)

It was a dull day on Shetland.

Puffin (Fratercula arctica)

Late tonight. Back at the Isles of Shetland.

Dunlin (Calidris alpina)

The commonest small wader found along the coast. It has a slightly down-curved bill and a distinctive black belly patch in breeding plumage. It feeds in flocks in winter, sometimes numbering thousands, roosting on nearby fields, saltmarshes and shore when the tide is high. (RSPB)

Black Guillimot (Cepphus grylle)

Back to the Isles of Shetland.
Its striking black and white plumage and bright red feet make it easy to identify in summer. Unlike most other European auks the black guillemot is typically found in ones and twos, scattered around rocky islets. It is typical of the larger sea lochs of western Scotland, and the northern and western isles, but is also found in Ireland, the Isle of Man and in a handful of spots in England and Wales.
