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:

Differs from Baillon's Crake in long primary projection in all plumages. At least 5 tips of primaries visible behind tertials. Adult birds show red base of bill, but this is sometimes difficult to see and immature may lack this altogether. Male with lead grey underparts, female with grey face and buff underparts. Immature with barred and spotted underparts but less so than immature Baillon's. The crown is also more evenly dark together with dark ear coverts. The species appears slimmer than Baillon's Crake due to longer neck, tail and legs.

Sound:

Rich repertoire of calls used freely in breeding season. Male song diagnostic. A loud series of short, nasal ascending "quek" repeated every one and a half seconds or so, before accelerating and descending at the same time to a more guttural voice. Female song with similar short "quek" but with less pure tone and in shorter series (sometimes just one call), immediately followed by a rolling trill.
