Appearance:

Slender and elegant harrier, with narrow wings and four "fingers". Adult male easily recognized by very pale grey and white plumage, with diagnostic wedge-shaped, black wing-tips (outermost primary grey). Female and immature birds often difficult to tell from Montagu's Harrier and Hen Harrier. Adult female differs from Montagu's by lack of dark band on upper wing, and by diffuse, sooty inner underwing. Pale bands do not reach wingpit, and under coverts are darker. Differs from female Hen Harrier by noticeably slimmer wings (both hand and arm) and only 4 fingers (but beware moulting Hen Harriers). Immature similar to Montagu's with unstreaked, rufous underparts. Differs in pale tips of inner primaries, and dark half-collar and pale "boa".

Sound:

Some calls similar to Montagu's and Hen Harrier, but display call quite diagnostic. A thin, vibrating trill "peerrrrrrrr".

Appearance:

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.
