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:

Resembles a big, black Curlew, but can only be confused with Bald Ibis. Differs from this by longer, slender neck, rounded and feathered head, long legs (trailing in flight) and heavier bill. Bare parts greyish, not red. Adults with glossy green wings. Immatures and birds in winter plumage with white-speckled head and neck. Head and legs droops slightly below horizontal plane in flight, leaving a "hunched" impression. Wing beats faster than herons of same size. May glide longer distances, but does not soar like Bald Ibis. Flight formation loose, diagonal or in single file with undulating movements.

Sound:

Generally silent away from breeding ground. Dry, crow-like "garr garr", may be heard occasionally in flight. At breeding ground various guttural grunts, and piping, hissing sounds.
