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.

Appearance:

Small dabbling duck. Males unmistakable with broad white supercilium and high contrast between the dark mottled breast and the lighter flanks (visible at considerable distance). Female mottled in light brown colours with typical supercilium and contrasting eye-stripe. White spot at base of bill. Throat much lighter than in Teal. Both sexes with dark and fairly long bill. Head gives a square impression due to the flat crown. Speculum in flight shows narrow white edges, lacking Teal's broad front edge. Agile flight, but lacks the twists of Teals.

Sound:

Male display sound a characteristic dry rattling, like the sound of running fingernails along the teeth of a comb. A bit similar to Ptarmigan. Also heard at other times than when courting. Female: like female Teal, but typically a bit deeper and shorter calls.
