Appearance:

Unmistakable due to the extremely long, red legs. High contrast plumage with pointed, black wings (both upper and under-side) and white underparts. Tail white, with white wedge extending up back. Back of adult male sooty black, while brownish black in female and immature. Head all white or with black markings independent of sex (males more often have black markings than females though). Immature with faint, pale fringes to coverts, and white trailing edge to secondaries visible in flight.

Sound:

Most vocal at breeding ground. Various short,sharp "kyp" may resemble both Avocet, Coot and Spur-winged Lapwing (Vanellus spinosus). While a tern-like "kee-arr" is more distinct. Note that immature birds have a different contact call closely resembling Wood Sandpiper, but do not utter it in series.

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.
