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.

In all plumages recognized by its long tail, call, and choice of habitat (reeds). Male unmistakable, with bluish grey head, yellow bill and black drooping moustache. Females and juveniles mostly plain, yellow-brown with whitish underparts and no moustache. Young females with dark bill, young males with yellow bill and black lore. Juveniles with black patch on back and black outer tail feathers. Flight whirring and undulated. Sometimes fans tail in flight with twisting motions.

Sound:

More often heard than seen. Usually identified by contact call; a ringing, explosive "tschin" with a characteristic "dirty" timbre. Also a hard and very short "pit", often mixed with the previous. Song a primitive, 3-syllable phrase, consisting of contact call-like sounds.
