Appearance:

Rather large and heavily built Sylvia with dark hood and pale iris (in adults). Lacks red orbital ring of Sardinian Warbler. Very similar to Western Orphean Warbler (S. hortensis), but usually distinguished from that geographically by different breeding and wintering range, and also by appearance in typical birds (in addition to song). The following field marks differs from S. hortensis; dark centres to under tail coverts and whiter underparts with very little buff tones (slightly buff flanks in some). Other more variable traits are; dark hood more distinctly bordered in neck, colder grey upperparts and longer, more curved bill. Vagrant immature birds outside of normal distribution may be impossible to tell from S. hortensis. Apart from size, it differs from Lesser Whitethroat by; stronger bill, lack of incomplete white eye-ring, darker upper tail and above mentioned under tail coverts.

Sound:

Contact call a short "check", sometimes in series. When agitated a nasal, rattling "trrrr-trrrr-trrrr". Both calls very similar to S. hortensis. Song distinct, but with same quality of fluting sounds as in S. hortensis, recalling that of Blue Rock Thrush in timbre. Phrases often long and much more varied and impressive, with frequent mimicry. May be mistaken for Nightingale, but incorporates more dry trills, is slower, harder and lacks the diagnostic series of plaintive notes (may mimic it!).

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".
