Mediterranean Short-toed Lark (Alaudala rufescens)
Arctic Tern (Sterna paradisaea)
Small lark with short, blunt bill and markedly streaked breast. The long primary projection is not covered by the tertials, as in (Greater) Short-toed Lark. Upperparts browner, and the dark shoulder patch og GSL is missing. Supercilium reaches all the way to bill-base. Wing-markings diffuse. Flight and behaviour similar to GSL. Sometimes performs song flight in characteristic "slow motion".
Sound:Contact call most diagnostic. A drawn, rattling "prrrrrrrt". Longer than in GSL, and less defined. Last syllable (t) accented and with a lower pitch. Song more continuous than in GSL, with a jerky rhythm and lots of mimicry. Listen for the interweaved contact calls.

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.
