The smew is a species of duck and is the only living member of the genus Mergellus. The genus is closely related to Mergus and is sometimes included in it; genetic studies have shown that it is the sister taxon to Mergus and Lophodytes. The smew has hybridised with the common goldeneye.
Where and when to see it
This is a sensitive species: FinBIF hides when and where most of its sightings were made, so no places are suggested.
