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.

Appearance:

An almost featureless, large warbler with greyish brown upperparts and buff underparts. Lack of distinct characters is a character! Most distinct character is probably the faint, slate grey half-collar. Vent has no markings, eye is dark and bill is relatively short. Body quite plump, and facial expression gentle and mild. Usually stays hidden in foliage. Lacks nervous behaviour of other Sylvia, and does not normally flick its tail and wings.

Sound:

Song: a full bodied, flowing, melodious stream of notes, distinguished by its almost constant, warbled quality and lack of clear whistling notes (see Blackcap). Tempo is fairly even. Beware confusion possibility with occasional subsong of Blackcap that never reaches the whistling part! Call a nasal "che". Alarm call a hard "check", and a hoarse "tcherr".
