Jack Snipe (Lymnocryptes minimus)
Roseate Tern (Sterna dougallii)
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.

Differs from Common and Arctic Tern by; noticably shorter wings, longer streamers, much paler grey upperparts, pure white underparts (faint rosy wash not very conspicuous), black bill (red base in breeding birds), dark outer primaries and no dark edge to inner primaries. Amount of red in bill increases as breeding season progresses, but also varies geographically. Wingbeats shallower and much quicker than in Common and Arctic Tern. Fishes with characteristic diagonal dives. Despite the long streamers, the birds appear short-tailed in flight, but head and bill are long and slender. The pale plumage, dark bill and giss recalls a small Sandwich Tern. Adult winter plumage with all dark bill and white forehead. Juveniles resembles juvenile Sandwich Terns, with more complete dark cap than Arctic and Common, and much more contrasting markings on back (especially to wings).
Sound:Extremely harsh calls. Like mix of Caspian and Arctic Tern. Very hard and raspy "kreeeet", harder and higher pitched than Caspian Tern, but equally harsh. Other calls include more Arctic/Common tern-like short "kek", and similar.
