Long-tailed Jaeger (Stercorarius longicaudus)
Reed Warbler (Acrocephalus scirpaceus)
Breeding plumaged adults with streamers unmistakable (streamers comprising two thirds of total tail length). Adult plumage shows less variation than in other skuas. No hint of breast band, and transition between pale belly and darker vent very diffuse. No white patches at base of primaries of underwing in adults. Juveniles easily confused with juvenile Arctic Skua, but are more slender. Wings narrower and primaries and tail longer. Juvenile Arctic Skua shows white patches at base of primaries on both sides of wings, juvenile Long-tailed only on underwing, and on first few primaries of upper. Barred rump and tail coverts in juveniles. Flight elegant and buoyant.
Sound:Calls sharp and less full-bodied than Arctic Skua, and not so mewing. Short, double-accented "kew-wev" or short "kerk" in agitation. Also a long drawn-out "keeeeaah", resembling both Arctic Skua and Common Gull.

Plain and characterless warbler with secretive behaviour. Larger than Sedge Warbler, with larger wings, broader tail and tail-base. Very similar to Marsh Warbler, and very hard to distinguish by plumage alone. Rump of Reed warbler warm rufous brown, warm buff flanks (yellowish tinge in Marsh Warbler), and slightly longer and more pointed bill. Differs from Blyth's Reed Warbler by longer primary projection, yellowish lower mandible and paler legs. Juveniles especially hard to identify, because of even fainter plumage field marks. Attached to reed beds.
Sound:By far easiest to identify by song: Characteristic, almost metric and even rhythm, very different from Sedge Warbler. Squeaky timbre with many, almost bizarre, harmonics. Phrases generally repeated 2-3 times. Alarm call a harsh, dry and rolling "kraaaat".
