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.

Appearance:

Smallest falcon. Male with slate grey upperparts, and pinkish buff, speckled underparts . Female dark brown above and heavily speckled below. Due to the extensive markings, the underparts give a darker impression than in Kestrel. Tail of female with dark broad bands, tail of male with broad black terminal band. Diffuse facial markings. Short wings. Silhouette similar to Peregrine, but the much faster wing beats are diagnostic. Acrobatic flight with sharp twist and turns when chasing prey. Alternating glides and bursts of wing-beats gives undulating flight.

Sound:

Series of harsh "kwik-wik wik". Coarseness similar to Peregrine, but pace much quicker. Female call harsher than male. Lacking the clearer tones and attack of Kestrel.
