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:

A large, and often shy, thrush. Most similar to Song Thrush. Other than size, it is distinguished by a long tail with white corners, white under wing-coverts and a pale, vertical cheek patch. Underparts are boldly covered in round (not arrow-shaped) spots that forms a dark patch on each side of upper chest. Rump slightly paler than the olive back. Noticeably bulkier than Fieldfare, with a heavier bill. Posture upright when foraging on ground, and head seems paler than the back. Flight non-undulating, but with alternating bursts of wing-beats and glides with folded wings. Often flies high.

Sound:

Song loud, far reaching and melodic. Most similar to Blackbird, but pitch is higher, phrases shorter (3-6 notes) and most notably, pauses between phrases are much shorter. All which gives the song a much more hurried feel than that of the Blackbird. Timbre is thinner and slightly shivering, and tonal range more limited. May have recurring favourite motifs, but does not repeat phrases like Song Thrush. Sometimes adds higher pitched parts and imitations. Other calls; a dry rattle, likened to the sound of a piece of wood drawn over a coarse comb, and a Fieldfare-like "chuck".
