Steller's Eider (Polysticta stelleri)
Ferruginous Duck (Aythya nyroca)
Diagnostic, squarish head profile with flat crown, high bill base, steep forehead in all plumages. Male unmistakable with white and orange-buff underparts, white head with dark eye-patch, black collar and black back. Female mottled brown, but distinguished by head profile and blue wingbar with white edges. Identifiable at a distance by its habit of holding the tail raised clear of the water like a dabbling duck.
Sound:Male seldom heard. Display sound probably a clear whistle rising slightly and then falling in pitch, a bit like Golden Plover. Female more noisy with indistinct guttural sounds.

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.
