Appearance:

Adult male unmistakable if seen well. Body and head bright yellow, lores, wings and tail black. Females and young males less distinct, with lime-green back, pale, streaked underparts and black wings and tail. Bill quite strong with reddish colour in adults, and grey in young birds. Despite the bright plumage the bird is difficult to see due to skulking behaviour in foliage. Usually spotted when moving from tree to tree in undulating flight. Then resembles a large thrush or woodpecker, quickly darting upwards into the next tree-top.

Sound:

Varied repertoire, but song and common contact call very distinct. Song a series of 1-2 seconds long phrases of 3-5 yodeling, clear, fluting notes, interspersed with 2-3 second pauses. Tone very full-bodied, melodic and pleasing. Contact call surprisingly different: A forced, drawn "weeackt", slightly resembling Jay, but less harsh, and much more nasal. Other sounds include a Wryneck-like warning call.

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".
