Appearance:

Gives a bulkier impression than Skylark, with longer bill, heavier head and body, and broader tail. In flight broad wings and short tail prominent. Lacks white edges on wings. Orange buff underwings. Crest on rear crown spiky and uneven. Outer tail feathers rufous, not white. Occasional song-flight. Slower wing-beats than skylark. Very similar to Thekla 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. Then habitat, behaviour and voice becomes important to identification, and a combination of structural and plumage character should be used. Bill appears curved (because of straight lower mandible), crest spikier than Thekla, belly deeper, back less heavily streaked , tail coverts less rusty-brown, upper breast usually with less defined streaking. Eye-stripe buffish, rather than white behind eye. Less prone to perch on top of scrubs or bushes than Thekla, and prefers lower altitude .

Sound:

Song: a mix of long whistling, fluting sounds, trills and mimicry. Full song quite similar to Thekla Lark. Rudiments of song are often heard and includes more melancholic whistling than Thekla. Contact call/alarm-call: May be the best characteristic to separate it from Thekla Lark where both species occur. Crested Lark call with 2-4 syllables, of which one is extended and fairly flat. The phrase has a less "bouncing" feel to it than Thekla Lark, lacking the accented rapid rise and fall in pitch of the extended note of Thekla Lark.

Appearance:

Adults in summer at close range unmistakable. Bill in juveniles almost black, and much less deep than in adults. Adults in winter plumage also show much darker bill and cheeks than in summer. At a distance head gives an all dark impression, with characteristic dark "shadow " in front of the eye. Head and bill less elongated than in other auks. Wings rounded with dark undersides. "Thighs" dark. Flight fluttering and energic, with shifting weight and angle.

Sound:

Deep, but not so coarse as Razorbill. Smoother and more gliding changes in pitch, like a "slow-motion" laugh or distant chainsaw; "aaaahrrr, aahr, ahr arh".
