Appearance:

Shows no red patches in any plumages. Only woodpecker in WP with barred flanks. White stripes extends from behind eye to back and from base of bill to scapulars, but head is generally much darker than in other pied woodpeckers. Crown in male yellow, in female speckled white.

Sound:

Drumming powerful and slow, with each beat clearly distinguishable. Most similar to Black Woodpecker but not as long (1 - 1.4 seconds). Accelerated ending (just the last few beats). Contact call similar to Great Spotted, but deeper and softer. Not very vocal.

Appearance:

Forked and fairly long tail. Clearly bigger than Storm Petrel, with more slender appearance and longer wings. Generally not as black, and shows brownish tone to plumage. The white rump patch is oval, has a weak grey center stripe, and does not reach as far down on the sides as in Storm Petrel. Light grey upper greater coverts form a wing-band. Underside of wings all dark. Flight pattern variable, with frequent changes in direction and speed. Sometimes glides like a shearwater but at other times shows surprisingly deep wing-beats. Does not patter surface, but will rest on water. Visits breeding ground only at night, and is usually only seen after storms.

Sound:

Only calls at breeding ground. A series of accentuated cooing, interrupted by a squeaky "inbreath" and a loud, absurd, fanfare-like "kaaa-ka-ka-kaaa-ka".
