Snipe (Gallinago gallinago)
Roseate Tern (Sterna dougallii)
By far the most common snipe in most areas. Bill longer than congeners. Belly white, in contrast to barred flanks. Upperparts of wings with white trailing edge, underparts with white wingbars. Diagnostic escape flight when flushed, with zig-zag change of direction, characteristic call and long period of circling the area before landing (or leaving altogether).
Sound:Quite vocal, especially at breeding ground. Almost always give diagnostic hoarse and nasal "kaaat" call when flushed. Song an unmistakable bleating, drumming sound produced by vibrating tail feathers in sky-dives. Another territorial call is a rhythmic, mechanical and sharp "tika-tika-tka", or "ika-ka-ka".

CCDiffers 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.
