Sedge Warbler (Acrocephalus schoenobaenus)
Cory's Shearwater (Calonectris diomedea)
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.

CCA 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.
