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 small, almost sparrow-sized, woodpecker. Most likely to be confused with Great Spotted Woodpecker, but vent never red (always in Great Spotted). Back heavily barred, and underparts streaked. No large patches of white on upperparts. Male with red crown, female purely black and white. Bill small and slender. More likely to be seen foraging in branches than most other woodpeckers. Fluttering flight.

Sound:

Frequently drums in quite long series. Much longer than Great Spotted, and without ritardando. Most common call a series of merlin-like "ke-ke-ke-ke-ke-ke" given at fairly stable pitch, and less hoarse than Merlin. Differs from Wryneck in lacking marked rise and fall in pitch, and being less plaintive.
