Rock Dove (Columba livia)
Brünnich's Guillemot (Uria lomvia)
Clearly smaller than Wood Pigeon. Plumage highly variable, and some morphs quite similar to Stock Dove. Differs from latter in complete dark wingbars on secondary coverts (not only inner coverts). Back light grey, contrasting with darker grey neck and head. Often with white patch at lower back, but not always. Underside of wings very pale, and dark trailing edge of tail fairly narrow. Lacks Wood Pigeon's white wing-patches. Feral Pigeon is the same species as Rock Dove. The existance of a population of pure wild Rock Doves without any mixed genes from feral populations anywhere in the world is debateable. There are many traits that can determine a bird as feral (like asymmetrical pigmentation), but birds with "classic" wild Rock Dove plumage also exists in the feral populations.
Sound:Not loud. Song a two-syllable, but continuous cooing. First a rolling ascending "orrrrrr" immediately followed by a short descending "oohh". Wings produce a quite audible whistling sound.

CCHard 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.
