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.

Quite vocal. Most common call a short, far reaching and extremely harsh, rasping sound. At breeding ground a varied repertoire of harsh and clattering sounds.
