Shag (Gulosus aristotelis)
Large diving duck with elongated, triangular head profile and short neck. Male: white upperparts and black belly, black cap and two light green patches at back of head. Females are mostly barred in brown. Differs from King Eider by extended feathering on light tipped bill, triangular head profile with less steep forehead and lack of v-barred flanks. Flying birds gives a more elongated impression than King Eiders.

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.
