Arctic Tern (Sterna paradisaea)
Great Snipe (Gallinago media)
Differs 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.

CCUnderparts almost completely barred. Prominent white edges to primary and secondary coverts. Shorter bill than Common Snipe, with stockier body, but slightly longer wings and legs. Less obvious trailing white edge to secondaries in flight. Corners of tail white (obvious when landing). Usually flies only a short distance and in a straight line after being flushed. Bill held in straighter angle than Snipe in flight.
Sound:Sometimes utters a faint grunt when flushed, but is generally silent when not lekking. Display call unique: A bubbling, clappering and whistling sequence that accelerates into a crescendo followed by a decrescendo.
