Eastern Orphean Warbler (Curruca crassirostris)
Alpine Chough (Pyrrhocorax graculus)
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!).

All black plumage, red legs and relatively short and straight, yellow bill. Note that immature Red-billed Chough has yellowish-brown bill, but never as pure yellow as in Alpine Chough, and the whole bill is curved. Easily confused with Red-billed Chough at a distance where both species occur, but note more narrow, less fingered wings, and longer, more rounded tail. Resembles Jackdaw in size, but flying Alpine Choughs differs by two-toned underparts of wings (darker coverts). Flight acrobatic, but a little more stilted than Red-billed Chough.
Sound:Diagnostic and very different from Red-billed Chough. A sharp, quite high-pitched, whistling trill "chreeeee". Usually alternated with pure-toned high-pitched whistles, falling abruptly in pitch with a "clipping" ending.
