Appearance:

Summer: Black throat framed in fine white stripes at the sides, and a chequered black back. Winter: More contrast between dark and white parts than in Red-Throated Diver. Marked transition between dark neck and white front, and the dark grey crown extends below the eye. In all plumages: Heavier neck and bill than Red-Throated, and bill usually held straight. Visibly protruding chest when swimming. Head shape sometimes squarish. Usually shows big white flank patch.

Sound:

Song: a strong, very resonant, full bodied, low whistling with most syllables rising in pitch: "co clooo-eee, co clooo-eee, co clooo-eee". Also a short grunting "karr".

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.
