Fairly small shearwater with jet black upperparts, and pure white underparts. Armpits often with dark markings. White notch behind wing base. Distinguished from Yelkouan and Balearic Shearwater by the always pure white vent. Faint, white wedge behind ear coverts. Legs do not protrude behind the tail. Flight typical of family: Rapid, shallow and stiff wing-beats, with alternating glides. Sometimes with only the primaries moving.

Sound:

Vocal at breeding ground. The call is sharp and wailing, and consist of two parts. A drawn, "inhalation", is immediately followed by a trisyllabic "ka-ya-ya".
