Tundra Swan (Cygnus columbianus)
Egyptian Goose (Alopochen aegyptiaca)
Easily confused with Whooper Swan, but yellow on bill restricted to a rounded patch. May sometimes extend towards the bill-tip, but never beyond nostrils. Angle of mouth bold black. Gives a more compact impression than Whooper, due to shorter neck. Head shape noticeably more rounded, and seemingly larger. Juveniles paler grey than Whooper, with the same bill pattern as in adults, but in faint, pale yellow and pink. Flight easy and goose-like.
Sound:More vocal than other swans. Both higher pitched and deeper sounds. Birds on the water often gives crooning, crane-like notes with less defined pitch. Tone is less full-bodied in these calls. Flight call a deep, yelping, soft barking sound. Each call short, with a "helpless" quality.

CCMay be confused with Ruddy Shelduck, but differs in long, pinkish legs, pink bill, long neck, greyish underparts and striking, brown mask. Conspicuous black and white wing pattern similar to Ruddy Shelduck, but crossed with a thin, black stripe. Sexes similar. Immature duller and without facial mask, and thus closer to RS in appearance. Spends much time foraging while walking, but may also dive. Flight heavy and goose-like.
Sound:Quite vocal when interacting. Female calls may resemble RS, but are coarser, harder and trills are more rolling. Single calls are longer, and falls markedly in pitch. Male calls quite different, with husky, wheezing or hissing "kaahhh", or with the same timbre in series lika a steam engine.
