Black Tern (Chlidonias niger)
Golden Plover (Pluvialis apricaria)
Unmistakable 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.

CCUnmistakable in breeding plumage with golden, speckled upperparts and white-bordered black throat and belly. Male generally blacker than female, but due to regional differences, some females may be darker than males from other areas. Juveniles and birds in winter plumage, lacks the black underparts, and could be mistaken for Grey Plover. Differs from that species in more golden coloured back, less heavy bill and neck and by being slightly smaller. In flight easily told apart from Grey Plover, Pacific Golden Plover and American Golden Plover by white axillaries.
Sound:Most common call at breeding ground a disyllabic, melancholic and wailing whistle with the end falling in pitch. In song flight also a trilling, warbling and cyclic "preecaria-preecaria-preecaria". Contact call a straight, short "kluee".
