Appearance:

Small thrush with rufous flanks, strong white supercilium and whitish moustache stripe. Upperparts evenly brown, underparts white with dark spots on chest and sides. Underwing coverts rufous. Fairly compact build, with slightly more pointed wings and shorter tail than Song Thrush. Juveniles less brightly coloured, with buff spots on upperparts. Behaviour less secretive than Song Thrush.

Sound:

Song delivered in two parts. First a simple, melodic phrase of 3 - 6 notes, usually followed by a more silent, indistinct, fast and less melodic, chattering sequence. First part highly variable from place to place, but constant in individuals. Often causes confusion when a new dialect is heard at a distance, since only the first part is far-reaching, and the diagnostic two-part structure gets lost. Contact call a thin, drawn and sharp "sreee". Often heard at night during migration. Alarm call harder, dryer and more raucous than other thrushes.

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.
