Appearance:

Rarely seen, small petrel. Compact with shorter wings and tail, and blacker plumage than Leach's Storm-Petrel. Squared, unforked tail. White patch on upper tail coverts that reaches down on each side, with more square-cut edges than in Leach's. Also lacks the grey upper wing-band of latter, but shows white stripe on underside of wing. Flight-pattern bat-like with quick fluttering wing-beats and less powerful, and only short, gliding sequences. Sometimes patters with feet on the surface or rests on water. Visits breeding ground at night.

Sound:

Heard at breeding ground. Dry, cyclic, rattling and cooing, interrupted by deeper nasal moaning or a higher pitched "kee-ee-kee", with emphasis on second syllable.

Appearance:

White with black wing tips and yellow-buff at back of head. Juveniles brown with small pale speckles, white u-shaped rump patch and pale underparts. Fully coloured only after 5 years, and patchy, intermediate plumages often seen. Unmistakable bird at close range or with favorable light, but can be confused with shearwaters at a distance and/or in strong wind. Differs from those by long tail and much longer neck and head. Alternates between powerful, even and shallow wing-beats and glides. Flight becomes more shearwater-like in strong winds.

Sound:

Heard mostly at breeding ground. Even, rhythmical series of harsh "harrr, harrr, harrr,".
