Great Northern Diver Gavia immer - At Sea

I was delighted to see this Great Northern Diver in its smart adult summer plumage from the ferry boat crossing back to the mainland from Mull. Whilst on Mull this April most of the others I saw were still in winter plumage. Once they dive they stay under water for a minute or more covering some distance before reappearing elsewhere. Its large feet which project behind its tail are just visible here.

 

Thank you all for your kind responses.
