Smew (Mergus albellus)

Content Image

The smew (Mergellus albellus) is a species of duck, and is the only living member of the genus Mergellus. This genus is closely related to Mergus and is sometimes included in it, though it might be closer to the goldeneyes (Bucephala). The smew has interbred with the common goldeneye (B. clangula).

The drake smew, with its ‘cracked ice’ and ‘panda’ appearance, is unmistakable, and looks very black-and-white in flight. The females and immature males are grey birds with chestnut foreheads and crowns, and can be confused at a distance with the ruddy duck; they are often known as “redhead” smew. It has oval white wing-patches in flight. The smew’s bill has a hooked tip and serrated edges, which help it catch fish when it dives for them.
