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:

Small, but tall and elegant Tringa. Body the size of Wood Sandpiper, but stands as tall as Greenshank. Tibia especially long. The needle-like, straight bill adds to the elegance. Pale face, especially at base of bill. Back grey in adults, with star-shaped speckles in summer and narrow, pale fringes in winter. Immatures with broader fringes and overall darker upperparts. In flight the long legs trails far behind the tail, and the narrow white wedge on the back is conspicuous. Wings are dark with no bars, and shows as the darkest part of the bird also when on ground (especially in adults). Surprisingly quick and easy take-off. Posture generally erect and tall, particularly when nervous.

Sound:

Song a slow, melancholic whistle "tu-lee-uu", with the middle part highest in pitch (and with falling glissando). Similar to Spotted Redshank in structure, but with a clear tone (little risk of confusion). Flight call/contact call similar to singular instances of alarm call of Redshank, consisting of a single note rising abruptly in pitch in a split second and then falling; "kieew". Lingers a bit at the ending of the note, giving it a clearer glissando than in Redshank.
