Thekla's Lark (Galerida theklae)
Short-eared Owl (Asio flammeus)
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.

CCA medium sized owl, which can give a very pale impression in flight. Quite similar to a Long-eared Owl with folded tufts, but differs in bright yellow eyes, darker wing-tips and heavily streaked breast in contrast to pale belly.
Sound:Song: a series of 6-10 deep "ho"s evenly spaced. Much faster than long eared owl, and rising in pitch until the final "ho". Calls: a raspy, drawn, mewing "eeeeeeeeeah" (about 2 seconds), rising in pitch with accented ending.
