Appearance:

Rufous red face, throat and chest, framed in slate grey in adults of both sexes. Olive brown to grey upperparts and dull white underparts. Head rather large, and body rather stocky when plumage puffed, despite thin bill and slender legs. Juveniles lack the red front and are heavily spotted in buff on a dark brown body with barred chest. Adults pretty unmistakable when seen well. Flight usually low and darting, with quick changes of directions before disappearing in thick bushes. Posture usually erect with frequent flicking of tail and wings.

Sound:

Alarm call a thin, electric "tick", often in series with decelerating tempo. Song medium to very high pitched, with mostly clear tones with a liquid quality. Timbre reminiscent of Wren or Dunnock, but with a much more varied structure and tempo. Pitch ranges from very high to low, almost thrush-like, notes. No recognizable motifs. Often ends on a rising or falling pitch, giving it a "Chinese" accent.

Appearance:

Differs from Arctic Tern in longer head, and more orangy red, rather than deep red, bill. Tip of bill usually black. Legs longer, but tail streamers shorter than AT. Underparts of primaries with diffusely bordered dark trailing edge (sharply bordered in Arctic Tern). Upper side of primaries with dark wedge (less apparent in winter). Secondaries opaque. Crest more apparent than in Arctic Tern and underside whiter. Juveniles with buff back.

Sound:

Similar to Arctic Tern but deeper. Lacks latter's high pitched "tip-tip-tip" call, and the drawn out "kree-aaahh" call falls more distinctly in pitch.
