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:

Very similar to Crested Lark, and identification can be very difficult in areas where both species occur. The much used streaked-breast character is not always relevant because of regional variations among the many subspecies of both Crested and Thekla. Then habitat, behaviour and voice becomes important for identification. A combination of the following characters should be used to tell it from Crested: Bill appears straight (because of convex lower mandible), crest fuller and not so pointed, belly less deep, back more heavily streaked , tail coverts rusty-brown in contrast to rump, underwing coverts greyish white (not rufous), upper breast with defined streaking ("done with marker pen"). Eye-stripe white behind eye. Will often perch atop of scrubs or bushes, unlike Crested, and usually prefers higher altitude habitats.

Sound:

Song: a mix of long whistling, warbling sounds, trills and mimicry. Full song very similar to Crested Lark. Rudiments of song are often heard and is less whistling than Crested. The contact call/alarm-call may be the best characteristic to separate it from Crested Lark where both species occur. Thekla Lark calls with 3-5 syllables, of which one is often drawn out and "hangs" while falling in pitch, giving it a melancholic feeling (diagnostic). The phrase has a more "bouncing" feel to it than Crested Lark.
