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.
