Appearance:

Shape resembles both diving and dabbling ducks. Characteristic head profile with long bill, long sloping forehead and rather high rear crown (not unlike Pochard). White undertail usually visible also when on the water. Broad, white wing-bars and white underwing conspicous in flight. White undertail separated from white belly by brown band. Male with shining white eyes. Female with brown eye and less bright rufous tones to plumage. Immature similar to female, but with even less rufous. Immatures told from immature Pochard by by darker back, no facial markings and white (not grey) wing-bars. Note that Tufted Duck sometimes have white (but more diffuse) undertail. Beware also of hybrids with Pochard (note bill-pattern).

Sound:

Female call similar to female Tufted Duck's "kerr kerr", but thinner and with a strong, peculiar bi-tone. Male display call mostly consists of various short "chk" sounds.

Female:

Appearance:

Most likely to be confused with Black-tailed Godwit, but easily recognized in flight by plain dark wings, white wedge on back and barred tail. More difficult to identify when not flying. Generally more compact, heavier built and less upright than Black-tailed, and with clearly upcurved bill and shorter legs. Belly always unmarked. Base of bill dark in summer and pinkish in winter and in juveniles. Back with arrow-shaped streaking. Adult winter also streaked, and the pale supercilium reaches behind the eye.

Sound:

Quite vocal at breeding ground but mostly silent elsewhere. Varied repertoire of mewing and sharp sounds, some resembling Black-tailed, some almost Snipe-like. Contact call a sharp "kwee-kee-wee-kee", with alternating high and low pitch, and decreasing intensity. Display call a hard and sharp "kuwek-kuwek-kuwek-kuwek", with emphasis on second syllable.
