Description

This bird is very similar in general appearance to the cormorant (Phalacrocorax carbo), but is smaller and slightly slimmer (2). In breeding condition, adults develop a green gloss to the black plumage, and a black crest develops on the head (2). Outside of the breeding season, the plumage is duller and the bill is more yellow in colour (2), although there is a yellow patch at its base throughout the year (5). Juveniles have dark brown upperparts and pale underparts with a white chin (2). A variety of grunting and clicking calls are produced (2). The common name originates from the Old Norse word 'skegg' meaning beard, and refers to the crest (5).
