Appearance:

Unmistakable in summer with almost all black plumage. White oval wing-patches in all plumages. Only auk with white wing-panels. Bill quite slender and pointed, body and wings rounded. Winter plumage blotched in grey and white, with dark wings (with white coverts). Typically scans for food by frequently dipping forehead in the water.

Sound:

Call surprisingly high pitched. Quite pure, drawn out, plaintive whistling notes in same pitch range as Hazel Grouse.

Appearance:

Medium sized, green woodpecker with black mask. Crown red in all plumages. Females with black moustache stripe, males with red framed in black. Juveniles heavily marked with small black and white spots all over, and less prominent black mask. Bigger and more heavily built than Grey-headed Woodpecker, with longer and stouter bill. Often foraging on the ground. Flight undulated.

Sound:

Song similar to Grey-headed Woodpecker, but not as soft and fluty. Each phrase consist of a series of short "klee", with a laughing quality. Pitch drops slightly throughout the phrase, but not as markedly as in Grey-headed, and tempo is fairly constant (no ritardando). Short "kek" calls when excited and in flight. Drumming of 1.5 seconds duration with decelerating tempo, but not often heard. Another call is similar to Black Woodpecker; a series of resonant "klit-klit-klit-klit-klit-klit", but is less clear, has a more determined start and has less obvious rising pitch at the end of each syllable.
