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:

Dark, pale and intermediate morphs. Pale birds more common in northern parts of species range, darker morphs more common further south. Elongated middle tail feathers (projection comprising about half the total tail length), but not as long as in adult Long-tailed skua. White patches at base of primaries, both on upper and underside of wings. Dark morph chocolate brown with darker hood. Pale morph with white throat and belly and incomplete breast band. Relatively marked transition from pale belly to dark vent (as opposed to Long-tailed). Size close to Common Gull. Flight powerful, elegant and falcon-like. Juveniles with short but pointed middle tail-feathers. Confusion with other juvenile skuas very likely. Differs from Long-tailed in prominent white base of most primaries on upper side of wing (not just the first few feathers). Lacks the double white patch of Pomarine Skua's underwing, and shows less contrast between back and rump. Wings broader than Long-tailed but narrower than Pomarine. Approximately equal to distance from wing rear edge to tail-tip (projections excluded).

Sound:

Mostly heard at breeding ground. Most characteristic call is a mewing, kittiwake-like "aeeeee-ah". First syllable drawn-out and rising in pitch, and followed by a deeper conclusive second syllable "ah". Lacks the introductory double accent of Kittiwakes ("kitti-wake").
