White-winged Snowfinch (Montifringilla nivalis)
Thekla's Lark (Galerida theklae)
Unmistakalble where there is no overlap with Snow Bunting (almost always). Anonymous brown bird with white wing patch when seen foraging on ground. Views in flight are dominated by the white on wings and tail. Fairly long-tailed and passer-like. Distinguishable from Snow Bunting in all plumages by the combination of grey head and brown back. Bill dark in breeding season, and yellowish in winter. Female similar to male but slightly duller coloured. Does not perch in trees. Erect posture and frequent tail-flicking when foraging on the ground. Flight less loose than Snow Bunting, with more frequent glides on stiff wings.
Sound:Rich repertoire. Song a staccato, variable phrase, consisting of short burst of sharp chattering in uneven tempo. The timbre is ringing, rich in harmonics and partly rolling. Among the various contact call the commonest are a high-pitched, sharp "zeet", a deeper, Brambling-like "veet, or a sparrow-like "peea". Alarm call a rolling "trr-r-r-rt", resembling Crested Tit.

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.
