Woodlark (Lullula arborea)
Black Tern (Chlidonias niger)
Bill finer than Skylark. Strong white supercilium reaching the neck. Distinctly streaked nape. Wings rounded, and with white edged primary coverts, but no white trailing edge as opposed to Skylark. Tail short and square with white trailing edge. Differs from skylark in posture and behaviour, and appears more erect when perched. Undecisive, bat-like flight.
Sound:Song: Distinct and quite slow for a lark. Consists mainly of varied, disyllabic elements, or single syllables repeated in descending, accelerated phrases. Starting soft and hesitantly, then gaining in strength and speed.

CCUnmistakable in breeding plumage, but otherwise easily confused with other marsh terns. Breeding plumage with black head and belly, but pale underwing and grey rump. When in immature and winter plumage it differs from Common and Arctic tern by smaller size and short, moderately forked tail, and from other marsh terns by slimmer body and wings (compared to White-winged tern), and relatively long, thin bill. Both immature and adult winter show dark front edge of wing, and characteristic dark shoulder patch at wing base. Back is dark in immature birds. Grey rump in all plumages. Flight usually different from Sterna-terns, with erratic dives for no apparent reason, and "aimless" change of direction. Note that when foraging over saltwater, flight becomes more Sterna-like.
Sound:Moderately vocal. Flight call a more or less clear "kleck, or a disyllabic "klee-ake" with accented first syllable. Sometimes slightly rolling "klirr-eke", but never as much as in White-winged Tern. Also a slightly harsher "kreek", but not as raspy as in Whiskered Tern.
