Guillemot (Uria aalge)
Ferruginous Duck (Aythya nyroca)
At a distance quite similar to Razorbill. Bill more slender, pointed and without white markings. Flanks streaked in black, and armpits with conspicuous black spot. Tail shorter than Razorbill. Cheeks white in winter, with thin black groove behind eye. Some individuals show white eye-ring and eye-groove in summer plumage. Differs from Brunnich's Guillemot in rounded, white wedge protruding from chest to throat, and all dark bill. Slender neck, head and bill, in combination with the short tail, gives it a different profile than Razorbill whether perched, swimming or flying.
Sound:Very coarse and deep voice. Typically rising in pitch, then ending on a prolonged stable note with a laughing quality. Sometimes only the coarse beginning uttered like "ga-ga-ga".

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.
