Jack Snipe (Lymnocryptes minimus)
Long-tailed Jaeger (Stercorarius longicaudus)
Notably smaller, darker and with shorter bill than Common Snipe. Two prominent yellowish back-stripes. Dark wedge-shaped tail, and slightly rounded wings. Lacks median crown-stripe. Flanks spotted, not barred. Diagnostic behaviour: Usually flushed only at close range. Takes off silently, then quickly lands nearby. Whole body bounces rhythmically when feeding.
Sound:May occasionally give a harsh, nasal and rolling "reearrr" when flushed, but is usually silent. Display call a peculiar, cyclic and rhythmic sound performed in flight. Recalling a galloping horse in the distance. "Galloping" interspersed with cyclic, whistling, hissing sounds. Hard to locate when displaying. Seems both close and distant at the same time.

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.
