Appearance:

A large and long-tailed thrush. Slate grey lower back, rump and head. Brown upper back and yellow buff breast with dark spots. The all dark tail contrasts with the grey rump. Tail colour combined with white underwing distinguishes it from all other thrushes when flying. Flight undulated in long waves, with alternating glides and bursts of wing-beats.

Sound:

Very vocal. Scolding call a hard "check", often given in decelerating series. Contact call in migration a soft, pleasant but, buzzy "weet". Song a mix of dry contact calls; "trrrt trrrrt", and high pitched, drawn out, chattering improvisations. Typically bursts into continuos, squeaky chattering at takeoff.

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.
