Appearance:

Differs from Common and Arctic Tern by; noticably shorter wings, longer streamers, much paler grey upperparts, pure white underparts (faint rosy wash not very conspicuous), black bill (red base in breeding birds), dark outer primaries and no dark edge to inner primaries. Amount of red in bill increases as breeding season progresses, but also varies geographically. Wingbeats shallower and much quicker than in Common and Arctic Tern. Fishes with characteristic diagonal dives. Despite the long streamers, the birds appear short-tailed in flight, but head and bill are long and slender. The pale plumage, dark bill and giss recalls a small Sandwich Tern. Adult winter plumage with all dark bill and white forehead. Juveniles resembles juvenile Sandwich Terns, with more complete dark cap than Arctic and Common, and much more contrasting markings on back (especially to wings).

Sound:

Extremely harsh calls. Like mix of Caspian and Arctic Tern. Very hard and raspy "kreeeet", harder and higher pitched than Caspian Tern, but equally harsh. Other calls include more Arctic/Common tern-like short "kek", and similar.

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.
