A diving duck with a high latitude, circumpolar breeding distribution, restricted in Europe to the Nordic countries and Siberian Russia. Winters mainly at sea or on coastal eutrophic lagoons in W and N Europe, with very small numbers on inland lakes in C Europe and along Mediterranean coasts. The European wintering population of Greater Scaup has declined significantly over the last 20 years, apparently because of short stopping and changes in food resources on the wintering grounds  (Cervencl & Fernandez 2012, Marchowski et al. 2020).
