Appearance:

Easily distinguished from Cormorant in breeding plumage, but at other times easily confused with congeners. Smaller than Cormorant, with a more slender neck and rounded head. Bill slender and straight. Steep forehead with peaked front crown, differs from the wedge shaped head of Cormorant. Bill often with yellow tinge (never in Cormorant). Flies with quicker wing-beats and straight neck (Cormorant with bulge). Often dives with a high jump. Juveniles with darker underparts than Cormorant, and often an obvious brownish tinge. Rare in brackish water.

Sound:

Very deep and harsh voice heard at breeding ground. Deep grunts alternated, or ended with clicking sounds.

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.
