Appearance:

Fairly small shearwater with jet black upperparts, and pure white underparts. Armpits often with dark markings. White notch behind wing base. Distinguished from Yelkouan and Balearic Shearwater by the always pure white vent. Faint, white wedge behind ear coverts. Legs do not protrude behind the tail. Flight typical of family: Rapid, shallow and stiff wing-beats, with alternating glides. Sometimes with only the primaries moving.

Sound:

Vocal at breeding ground. The call is sharp and wailing, and consist of two parts. A drawn, "inhalation", is immediately followed by a trisyllabic "ka-ya-ya".

Appearance:

Small and compact, brown warbler with strong supercilium and streaked back. Crown dark with faint streaking, contrasting with broad supercilium. Rump unstreaked and warmer brown than back and tail. Juveniles with faintly streaked chest. Long primary projection. Body shorter and more compact than Reed Warbler. Easiest Achrocephalus to see in the region. Often sings from exposed branch or reed, is inquisitive and not very shy.

Sound:

Alarm call a hard "check". Anxiety call a dry and rolling "rrrrr". Song vigorous and varied. A mixture of musical sounds, expert mimicry and characteristic harsh and strident calls. Not as rhythmic and evenly paced as Reed Warbler, but varies tempo a lot.
