Appearance:

Differs from Herring Gull in smaller size, lighter bill and light flight. Head profile rounded, and the small bill lacks the red spot of the larger gulls. Told apart from Kittwake by greenish legs and large white spot on wing tips. Juveniles quite similar to young Ring-billed Gulls, but latter have paler grey back, heavier, pinkish bill with dark tip, pale mid-wing panel and less contrasting terminal band of tail.

Sound:

Various mewing sounds. Similar in form to Herring Gull, but much higher pitched.

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.
