Arctic Tern in Winter Plumage???

Observation - Arctic Tern in Winter Plumage??? - Global. Description: Small tern which at first I thought might be a Little (Least) Tern, but have now gone for a winter plumaged Arctic, although I am still not convinced. It did seem a bit too small. Any positive ID would be gratefully received.
