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:

Plumage a mix of rusty, creamy brown and grey, resembling a nightjar. A rather unmistakable bird, despite the lack of striking plumage features. Behaviour both passerine- and woodpecker-like, but with less woodpecker-like tree clinging. Often feeds on the ground. May give a reptile-like impression.

Sound:

Normally silent when not breeding. Song (both sexes): an insisting, Merlin- or Lesser Spotted Woodpecker-like series of plaintive "kee kee kee kee kee ". First slightly ascending, then descending. Other sounds: a guttural "gru", and hissing sounds when threatened.
