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".

Appearance:

Small and very elegant falcon, with white throat and rufous thighs (adults). Long, narrow wings and medium long tail. Dark grey above and heavily streaked below. Head dark, with marked facial pattern resembling Peregrine. Tail often looks slightly wedge-shaped. Impressive speed of flight, with acrobatic skills when hunting. Often hunts flying birds high in the air. Slower flight action when hunting insects. Will glide, but seldom hovers (as opposed to Red-footed Falcon). Perched birds shows wing-tips reaching end of tail.

Sound:

Varied, but not very vocal. Calls when courting and at breeding ground. Most common sound a high-pitched "tew-tew-tew". Similar to Wryneck, but less pleading. Also a sneezing "ktcho".
