Appearance:

Big and white waterfowl with orange bill and black knob at base of bill. Juveniles more greyish and differs from juvenile Whoopers by all grey bill and black lores. Neck usually held more S-shaped than other swans when swimming. Long tail prominent when upending.

Sound:

Silent compared to other swans. A repertoire of snorting, grunting and hissing sound when interacting. No far carrying sounds. Wings produce prominent singing sound which may function as a flight contact-call.

Appearance:

Fairly large rail with secretive behaviour. Distinguished by long red bill, brownish upperparts, slate grey underparts, and coarsely barred flanks. White and unmarked vent often visible due to frequently used posture with flirted tail. Long legs and toes visible in flight.

Sound:

Varied but distinct. Most heard is the territorial song consisting of short, nasal, sharp grunts "tuck- tuck-tuck", ending with a drawn-out trill rising and falling in pitch "kiiiieeerrrr". Another diagnostic call is heard from excited birds; a longer pig-like shrilling squeal, with waning repetitions. A bit like someone squeezing a rubber toy. Also short and sharp calls "kvii".
