Appearance:

Male unmistakable with its stunning colours. Broad, white eyestripe from bill to nape, and two conspicuous wing sails. Large head, compact body and long tail. Female and juvenile also distinct, but may easily be confused with Wood Duck. Differs from this by "clear cut" base of bill without wedges, less white around eye, paler head and coarser white markings on flanks. Juveniles similar to female, but browner and duller. Often perches on branches and logs.

Sound:

Display call a thin, whistling and rapidly rising "hueessst, accompanied by deeper clappering sounds. Other sounds include a short and sharp, coot-like "ket", and a short "ack".

Appearance:

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.
