Appearance:

Summer: Red throat (seemingly black at a distance!). Lacks white vertical framing of throat patch and white spotted back of Black-throated Diver. Winter: Quite pale. White face and eye-ring. Just a narrow stripe of dark grey along the back of the neck. In all plumages best identified by posture and silhouette, especially when seen at a distance. Slender neck, head and bill. Flat chest. Usually shows no white flank patch. Bill usually held uptilted.

Sound:

In flight; nasal, dry, gooselike series of rhythmic cackling "ko-ko-ko". Most vocal when courting and breeding. A meowing drawn-out sound starting with a register break, then falling in pitch. Display call a far reaching rolling cyclic cooing, given in long sequences.

Appearance:

Very similar to Thrush Nightingale. Anonymous, indistinct plumage and secretive behaviour makes it an easily overlooked bird (except when singing). Tail rufous brown, upperparts warm brown. Underparts buff and white. Throat without streaking. Tail more rufous, and contrasts less with the warm brown back, than in Thrush Nightingale. Overall a more smooth and clean appearance. Thrush-like behaviour despite the small size, with jumping gait, erect posture, raised tail and drooping wings.

Sound:

Alarm call either a thin, flycatcher-like "weeet", or a Chiff-chaff-like "piuu". Also a characteristic (but similar to Thrush Nighitingale) dry, rattling, frog-like "rrrrr". The song is the best characteristic to separate it from T. Nightingale. It consists of extremely resonant, full-bodied notes and lacks the, dry, rolling, rattling sounds of T.N. Most distinct species specific sound is the interwoven series of slightly ascending, plaintive notes (0.04 - 0.10 in recording). May mimic Thrush Nightningale!
