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.

Appearance:

Anonymous, indistinct plumage and secretive behaviour makes it an easily overlooked bird (except when singing). Upperparts brown-grey, tail rufous brown. Underparts dull white. Throat with faint streaking on each side. Very similar in appearance to Nightingale, but tail is not as rufous, and contrasts more with the grayer/brownish back. Overall more drab appearance. Thrush-like behaviour despite the small size, with jumping gait, raised tail and drooping wings.

Sound:

Alarm call alternates between a thin, high pitched, "piuu", and a characteristic dry, rattling, frog-like "rrrrr". Song a highly distinct mix of extremely resonant, full-bodied notes and species specific, dry, rolling, rattling sounds. Can only be confused with Nightingale, but lacks this species' interwoven series of slightly ascending, plaintive notes.
