Spotted Redshank (Tringa erythropus)
Thekla's Lark (Galerida theklae)
Unmistakable in breeding plumage, with all dark/blackish body unique among Tringas. Most birds seen in Europe will probably be in winter- or juvenile plumage, and can then be mistaken for Redshanks. Spotted Redshanks are slimmer, longer legged and more elegant than Redshanks. The supercilium is much more prominent, the bill is slimmer and longer. Most diagnostic is the lack of white wing-bars, and the white sigar-shaped patch on the back. The barring in juveniles reaches from the belly and all the way back to the vent. Often feeds in deeper water than Redshanks, even by swimming and upending.
Sound:Flight call loud and diagnostic, and is often the first sign of the species' presence; a sharp and short, disyllabic "koo-eett", with the first syllable falling in pitch and the second rising sharply. Display call a squeaky, but melodic "krroo-lee-ooo" repeated in cycles. Alarm call a falcon-like "ke-ke-ke-ke".

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.
