Caspian Tern (Hydroprogne caspia)
Golden Plover (Pluvialis apricaria)
Very large tern, with deep, dagger-like, blood-red bill with dark tip. Large, black cap reaching well below the eyes. Grey upperparts and white underparts. Rather short tail. Outer primaries distinctly darker than the rest of upperwing, and outer underwing almost black. Unmistakable from the size alone, and leaves a gull-like impression, lacking the elegance of smaller terns. Immatures with paler bill and white forehead (as in adult winter), and markedly speckled back. Hovers and dives. Often rests on the surface, feeding like a gull.
Sound:Easily recognized by its very harsh calls. Sometimes likened to the sound of a plate of steel being dragged across a concrete floor. Similar in harshness to Grey Heron, but more drawn, with an accented middle; "Kraaeeet", or with a double syllable start "ka-ha-kraaaeet". Immature birds begs with a penetrating, sharp whistle.

Unmistakable 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".
