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".

Appearance:

Notably smaller, darker and with shorter bill than Common Snipe. Two prominent yellowish back-stripes. Dark wedge-shaped tail, and slightly rounded wings. Lacks median crown-stripe. Flanks spotted, not barred. Diagnostic behaviour: Usually flushed only at close range. Takes off silently, then quickly lands nearby. Whole body bounces rhythmically when feeding.

Sound:

May occasionally give a harsh, nasal and rolling "reearrr" when flushed, but is usually silent. Display call a peculiar, cyclic and rhythmic sound performed in flight. Recalling a galloping horse in the distance. "Galloping" interspersed with cyclic, whistling, hissing sounds. Hard to locate when displaying. Seems both close and distant at the same time.
