Appearance:

Adult male easily recognized by black throat and strong white moustache stripes. Female often also with black spotted throat which, together with the moustache stripe and pale chest/belly, makes it easy to distinguish from other Sylvia. Females and immatures with pure white throat may be confused with female Sardinian Warbler, but show darker front half of head, paler and purer coloured belly and flanks (lacking brownish tinge) and white fringes to greater coverts and tertials (less obvious in worn plumage). For all plumages look for curved culmen, pointed bill and longer and squarer tail than Sardinian Warbler. Build more similar to Whitethroat than Sardinian Warbler, and also less agile than smaller Sylvia.

Sound:

Alarm call a rolling "trrrrrrrrt", similar to Spectacled Warbler, but less confluent (fewer pulses pr. sec.). Not as hard as corresponding call of Sardinian Warbler. Song a rapid mix of rolling alarm call type syllables, with interwoven single whistling notes. Rolling clearly softer than in Sardinian Warbler and often dominates the song with sequences of up to one second, giving it a very hectic feel. Each phrase rarely more than 2 seconds long. Some geographical variation exist and individuals with less rolling song easier to confuse with Sardinian and Cyprus Warbler.

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.
