Appearance:

Slightly smaller than Eider. Male at close range unmistakable. At a distance the black back is diagnostic. Female similar to female Eider, but feathering on bill is not reaching nostrils, giving the bird a peculiar "smile". Head shape is less triangular with a steeper forehead, and nail of bill is black. V-shaped barring on flanks.

Sound:

Male: Calls similar to Eider but easily distinguished by the vibrating quality. A "aaaooooooh" (shorter in duration than Eider) Starting on a low note, slowly ascending and ending on a descending note with a distinct vibrato/pulse. Often in the form of three calls: "oohh, a-ohhh hahahaoohohohoh". Usually accompanied by the female "ga ga ga ga".

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".
