Appearance:

A beautiful, very pale owl with a diagnostic, heart-shaped face and black eyes. Underparts white to buff. Buff-bellied individuals most likely to be confused with other owls, but note lack of barring and streaking. Instead the underparts may be covered in small spots. Underwing almost white. The white bellied birds may recall the much larger Snowy Owl, but has much slender wings, slender body, longer legs and protruding head. Posture upright, both on ground and when perched. Flight-pattern variable, but often hunts from low above ground in slow and buoyant flight.

Sound:

Large repertoire of mainly hissing and screeching sounds. Song consists of a single, drawn screech, lasting about a second and is often performed in flight. Starting in a very hoarse tone, then progressing with a rising pitch into a more burbling sound, before suddenly ending.

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".
