Appearance:

Adults easily recognized by red frontal shield and red base of yellow bill. Both adults and juveniles show bold white/pale lateral stripe. Appears totally black at distance, but can be told apart from Coot by more slender build. Tail usually flirted, showing diagnostic white under tail-coverts. This also shows in juveniles, which are further distinguished by darker bill and neck than Coot.

Sound:

Rich repertoire of loud calls and softer sounds. Most typical is the territorial call (song); a sharp, loud and resonant "krrrr-ook" or "krrrk". Other calls; a sharp, three or four-syllable "kekeke", and a soft "wep" sometimes drawn-out in a more mewing version.
