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:

Largest marsh tern. Liable to confusion with Sterna terns due to black cap, in addition to other marsh terns. All marsh terns (Chlidonias) differs from Sterna by lack of tail streamers, short tail with shallow fork, shorter wings and stiffer flight. Marsh terns don't plunge-dive for food but picks from surface (though Whiskered Tern may belly-plunge), mostly in fresh water. Adult Whiskered Tern easily told from other marsh terns by distinct black cap contrasting to white cheeks and throat. Underwing pale with diffuse dark trailing edge. Belly distinctly darker than Common- and Arctic Tern, but beware of variation in both species. Bill dark blood red. Adult winter: Very pale with no distinct markings except for ill-defined black mask stretching from eye to eye across nape. Forehead white and with crown white speckles. Bill black. Immature: Yellowish brown saddle with coarse dark pattern, though these are moulted in early autumn. Usually lacks dark carpal bar and cap ill-defined. Whiskered Tern generally stockier built than other marsh terns. Both immatures and adult winter show grey rump (different from Common, Arctic and White-Winged), and bill is dagger-shaped (most apparent in males).

Sound:

Contact call freely used and fairly distinct: An extremely hoarse, and rasping "krreek" in various moods. Timbre comparable to Corncrake. Sometimes uttered in stuttering series "kr-kr-kr-kr-kr".
