Snipe (Gallinago gallinago)
Arctic Tern (Sterna paradisaea)
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 Tern in shorter head, and blood-red bill. Legs shorter, but tail streamers longer (extends well past wings in sitting birds). Underparts of primaries with sharply bordered dark trailing edge (diffusely bordered in Common Tern). Both primaries and secondaries transparent to sunlight. Crest less apparent than in Common Tern and underside greyer. Cheeks white just below the black cap, often in contrast to grey lower cheeks. Juveniles lacks buff coloured back.
Sound:Similar to Common Tern but higher pitched. Typical call a series of high pitched "tip-tip-tip", and longer, ringing, high-pitched "kriiiiii" calls. The drawn out "kree-aaahh" call falls less distinctly in pitch than Common Tern.
