Black-necked Grebe (Podiceps nigricollis)
Arctic Tern (Sterna paradisaea)
Small and dark grebe, with squarish head and thin, uptilted bill. Adult breeding plumage distinct, with unique combination of black head and neck, and a spray of golden, fan-like feathers from eye to nape. Winter plumage birds are easily confused with Slavonian Grebe, but note dark, rear cheek-patch, and darker collar. Head profile distinct, with its steep forehead. In winter plumage highest point is above the eye, as opposed to nape in Slavonian. Much more contrasting plumage than Little Grebe. Avoids to take wing if possible.
Sound:Territorial song a disyllabic, flute-like "zoeeee-chk". First part drawn, ascending and plaintive, second part descending and clipping. Timbre is unpure. Other calls include chittering and trilling calls resembling Slavonian or Little Grebe.

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.
