Appearance:

Adults easily recognized by rufous cap, black back, white scapular patches and white rump. Appears more compact and bigger headed than Red-backed and Lesser Grey Shrike. White spot at base of bill larger in female than in male. Immatures told from Red-backed Shrike by whitish scapulars, greyer upperparts, diffuse patch at base of primaries, pale rump and dark brown tail. Young birds may also be confused with Masked shrike, but note less contrasting primary patch, darker forehead, browner upperparts and wings, pale rump, shorter tail and deeper bill. Subspecies L. s. badius lacks primary patch. More skulking than many shrikes. Likes high viewpoints.

Sound:

Alarm call a dry, magpie-like "che-che-che-che-che", or a nasal, ascending oriole-like "weea". Territorial song loud and varied. Often repeats phrases and includes mimicry. Alternativ song a more continuous chattering with impressive mimicry similar to Red-backed and Lesser Grey Shrike, and difficult to separate from those.

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".
