Appearance:

A big accentor with rufous flanks, finely mottled throat, and blackish wing coverts with white tips. Latter often the most obvious character in poor light, and is visible both in flight, and when on ground. Bill black with yellow base. Build stocky and recalls larks or pipits. Tail dark with narrow, white tip. Flight powerful, undulating and thrush-like. Jumps and runs on the ground, with a more upright stance than Dunnock. Sociable, and small flocks can be seen even in breeding season.

Sound:

Song is a varied stream of melodious and chattering notes, more resembling skylark than the much higher pitched Dunnock. Most common call a noisy "tchrt", often repeated in short, retarding series. Also has a more pleasant, ringing Snow Bunting-like "prrrriitt".

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.
