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:

Rufous tail with dark brown center in all plumages. Most noticeable in flight when tail is spread. Male unmistakable with black face and throat, white band across forehead, orange-red breast and grey back. Female relatively featureless, except for the characteristic rufous tail. Other characters are brown-grey upperparts, pale eye-ring, and orange tinge to breast. Erect posture with frequent tail flicking.

Sound:

Alarm call a slightly drawn, Willow Warbler-like "huit" with a rising pitch, followed by a short, soft "tuc". Song distinct, with three parts: First an ascending single note, immediately followed by a trill, then concluding with a squeaky, rattling improvisation that usually contains some mimicry.
