Small and compact grebe. May be confused with Red-necked Grebe or Black-necked Grebe. In all plumages; short bill and flat crown. Thicker neck than Black-necked Grebe and lacks steep forehead. Dark bill with pale tip, often surprisingly visible. Summer; chestnut neck, black head and golden crests. Sexes alike, but male slightly brighter coloured. Winter; black upperparts and white underparts (differs from Little Grebe). Pure white cheeks in adults (grey in Red-necked Grebe). Juveniles may show faintly streaked cheeks, but still giving a white impression.

Varied. Vibrating, wailing, dry and cackling sequences. A mewing, falling and far-reaching "kiaa" and various rattling sounds.
