Cormorant (Phalacrocorax carbo)
Stock Dove (Columba oenas)
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.

Clearly smaller than Wood Pigeon, and lacks white wing-patches. Most susceptible to confusion with Feral Pigeon. Differs from latter in incomplete dark wing-bars, covering only inner secondary coverts. Colour of back same grey tone as neck and head. Never with white patch at lower back. Underside of wings grey, with clearly defined dark frame. Black trailing edge of tail fairly broad.
Sound:Song a two-syllable, cooing. Much louder and more accentuated first syllable than in Feral Pigeon. First a short ascending "oooh", immediately followed by a short descending "oohh". Tone quite pure, mostly lacking the rolling quality of Feral Pigeon.
