Appearance:

Small and slender Sylvia about the size of Lesser Whitethroat. The short wings, steep forehead and striking long tail alone is often enough for positive id. Upperparts dark slate grey, and underparts of male vinous red with finely white spotted throat. Female less brightly coloured with more brownish tones and less red underparts. Immature duller still, with brownish underparts rather than red. Yellow base of lower mandible in all ages and sex. Lacks the white moustache-stripe of Subalpine Warbler. Tail frequently held raised. Skulking behaviour. Prefers scrubs/Gorse and is usually only glimpsed when moving low from bush to bush, or when singing from more exposed perch.

Sound:

Contact call a diagnostic, very nasal "chirr", quite different from other Sylvia, and used freely. Warning call a har "tuc". Song similar to Sardinian Warbler, but usually identifiable by frequently interspersed contact calls. Phrases are quite short, and pauses are as long or longer than the actual phrases. Each phrase typicall starts and ends with a more tonal segment than the regular chattering.

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".
