Eastern orphean warbler (Sylvia crassirostris)

Classification: Genus Sylvia (Sylvia); Subfamily Sylviinae (Sylviinae); Family Old world warblers (Sylviidae)
Song: Song distinct, but with same quality of fluting sounds as in S. [Link]
Calls: Contact call a short "check", sometimes in series. When agitated a nasal, rattling "trrrr-trrrr-trrrr". Both calls very similar to S. hortensis. 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!). [Link]
