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:

A large shearwater with pale upperparts and heavy, yellowish bill. Large grey head. The grey neck forms a diagnostic, contrasting line from wing base to base of bill (most other shearwaters have white neck-sides). Armpits usually pure white. Underside of wings white, framed by black flight feathers. Flight action calm and distinct. Long glides alternates with 3-4 slow wingbeats. Wingtips always bent downwards, and wings slightly angled back. Often soars. Differs from Fulmar in dark tail, grey head, long, narrow wings and longer bill. The two subspecies C. diomedea and C. borealis, are somtimes treated as different species. Field identification of these usually impossible, and requires ideal conditions. Hand of borealis is darker due to no white fringes to primaries. In diomedea the white in the coverts extends in a white wedge into the hand, through the base of the primaries.

Sound:

Very vocal at breeding ground. Calls with a very nasal, comical, mewing "ke-kooeee", ending with falling pitch, like a releasing sigh or moan. Sometimes reltively pure, other times very hoarse and raucous.
