Appearance:

Biggest woodpecker in WP (crow size). All black with red crown (male) or nape (female). Unmistakable. Flight Nutcracker-like, "inefficient" and fluttering, almost without undulations.

Sound:

Most sounds diagnostic and very far reaching. Drumming very powerful and long (1.8 - 3 sec.) with slightly falling intensity and accelerated ending. Each beat clearly distinguishable as in Tree-toed Woodpecker, but duration much longer. Drumming:

Flight call a characteristic resonant trill "krrreekrrreekrrreekrrree". A characteristic short, sharp and plaintive "keeaaa" with descending pitch often uttered when excited. Song a quick series of "klee" calls resembling Green Woodpecker, but with a purer tone and upward infliction at end of each syllable. A few slower drawn-out introductory calls before the phrase gets going is diagnostic.

Small size diagnostic. Small head in relation to body size, and distinct short white supercilia. Slightly protruding bill. Rather dark face, with only fine white markings and stern look. Juvenile lacks finely spotted crown. Bounding, woodpecker-like flight.

Sound:

Calls in a clear voice, like a straight note blown on a recorder. Each note often followed by a rhythmic, trisyllabic accent a whole tone deeper than the first note.
