Appearance:

Largely unmistakable, even at a distance when bald head is not apparent. Note short legs and short, thick neck without bulbous head. In flight note that the legs are not protruding behind tail, and that the wings usually show 3-4 "fingers". Frequent soaring flight, as opposed to Glossy Ibis.

Sound:

Mostly silent. Vocal at breeding ground, where a range of guttural calls can be heard, "yarrp, yarrp" etc.

Appearance:

Occurs in dark and pale morph. Plumage recalling gulls more than shearwaters (especially pale morph). Differs from shearwaters in white or pale head, compact body, short and heavy bill and broad wings. Flight pattern distinguishes it from gulls, and is similar to other tubenoses. Glides on stiff wings with occasional bursts of shallow and stiff wing-beats. Pale base of primaries visible at considerable distance in both dark and pale morph. Dark morph most common in high-arctic areas, pale morph most common in southern breeding range.

Sound:

Mostly heard on breeding ground. Coarse, harsh, staccato calls when courting or quarrelling.
