Barn Owl (Tyto alba)
Thekla's Lark (Galerida theklae)
A beautiful, very pale owl with a diagnostic, heart-shaped face and black eyes. Underparts white to buff. Buff-bellied individuals most likely to be confused with other owls, but note lack of barring and streaking. Instead the underparts may be covered in small spots. Underwing almost white. The white bellied birds may recall the much larger Snowy Owl, but has much slender wings, slender body, longer legs and protruding head. Posture upright, both on ground and when perched. Flight-pattern variable, but often hunts from low above ground in slow and buoyant flight.
Sound:Large repertoire of mainly hissing and screeching sounds. Song consists of a single, drawn screech, lasting about a second and is often performed in flight. Starting in a very hoarse tone, then progressing with a rising pitch into a more burbling sound, before suddenly ending.

CCVery 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.
