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:

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.
