Appearance:

Big and plump-bodied diving duck with long neck, rounded head and long bill. Male unmistakable with it's red head, long deep-red bill, distinct white flank-patches and black belly. The contrasting light grey cheeks of the female recalls female Common Scooter, but note round head, pale body and much longer neck and bill. Both sexes with very broad and striking white wingbar clearly visible in flight.

Sound:

Female: Indistinct "ahrrrr -ahrrrr -ahrrrr" similar to other female diving ducks. Male: a nasal dry "qweeeek" similar in timbre to Goldeneye male, but mostly monosyllabic and with an almost barking quality.

Appearance:

Differs from Common Tern in shorter head, and blood-red bill. Legs shorter, but tail streamers longer (extends well past wings in sitting birds). Underparts of primaries with sharply bordered dark trailing edge (diffusely bordered in Common Tern). Both primaries and secondaries transparent to sunlight. Crest less apparent than in Common Tern and underside greyer. Cheeks white just below the black cap, often in contrast to grey lower cheeks. Juveniles lacks buff coloured back.

Sound:

Similar to Common Tern but higher pitched. Typical call a series of high pitched "tip-tip-tip", and longer, ringing, high-pitched "kriiiiii" calls. The drawn out "kree-aaahh" call falls less distinctly in pitch than Common Tern.
