It is slightly smaller and can be distinguished from its twin mainly by its lack of a white flank patch. A Pacific Loon was observed in the Upper Engadine in December 2015, causing an absolute sensation. The species, which normally winters on the Pacific coast, was first reported in Europe in 2007 in the UK. Since then, only few reports have followed, most of them also from the British Isles.
