Appearance:

Hard to distinguish from Guillemot, especially at a distance. Bill heavier, shorter, less pointed and with lateral white stripe at base (not obvious at a distance). Flanks lacks Guillemot's streaking, and armpits are white. Upperparts blacker, without brownish tones. Tail shorter than razorbill, with protruding feet in flight. Only lower cheeks white in winter, with the area behind the eye being black (white in both Guillemot and Razorbill). Pointed (not rounded) white wedge protruding from front of chest to lower throat. Neck, head and bill, heavier than in Guillemot, but more slender than Razorbill. Bill often tilted downwards in flight.

Sound:

Coarse and deep voice, like a cross between Guillemot and Razorbill. Coarser than Guillemot but with the same laughing ending, but slower.

Appearance:

Easily confused with Shag when not in breeding plumage. Cormorant is larger, heavier built, has a thicker neck and less rounded profile. Head diagnostically wedge-shape, with the back of the head as the highest point. Bill never yellow (but yellow naked area at base of bill). Juveniles usually with whiter belly than Shag, and with less brown tinge. Behavioural differences from shag; often dives without jumping, more common in brackish water, often flies high, and often chooses higher ground or objects when perching. Slower wing-beats than Shag, with more separated primaries. Subspecies sinensis with larger gular poach angle (se fig.).

Sound:

Mostly heard at breeding ground. Coarse, vibrating calls "hahahahaharo". Also deep, rattling and creaking sounds.
