Gull-billed Tern (Gelochelidon nilotica)
Redshank (Tringa totanus)
Easily confused with Sandwich Tern but choice of habitat usually different. Adults differs by noticeably shorter and deeper bill, lacking yellow tip. Wings are broader, tail is shorter and only slightly forked. Lacks crest. Primaries with dark trailing edge, especially underside. Rump pale grey, and there is no contrast between grey back and white tail as in Sandwich Tern. Loses the black cap in winter, but keeps a black mask (less black on head than Sandwich T). Immature birds also gives a paler impression. The back is almost uniform in colour, and the wings also have only diffuse markings. The dark trailing edge to the primaries is present though, together with dark eye mask. Rest of head is pale. Flight slightly front-heavy with shallow wing-beats. Catches insects in the air and from the ground in flight. Rarely plunge-dives. Prefers fresh water, and is often seen near wetlands, rivers and flooded fields, but also in salt water during migration.
Sound:Quite vocal and easily distinguished from most congeners. Mewing and sharp in tone, but not rattling or raucous like most terns. Most typical call is a disyllabic, mewing "ke-waat", with an upward inflection. Other variants are series of "ke-ke-ke-ke", or the mewing sounds.

CCAdults differ from most other waders by bright red legs. Large white rectangular patches on secondaries conspicuous in flight in all plumages. Spotted redshanks in winter- or juvenile plumage lacks white wing bars, are more elegant with a more slender bill, and shows a stronger dark eyestripe and white supercilium. Juvenile Redshanks are unevenly, and sparsely spotted below from the legs to the vent, as opposed to the barring of juvenile Spotted Redshanks. Leg colour in juveniles often dull yellowish. Flanks evenly spotted. Winter plumage with brownish upperparts.
Sound:Generally a noisy and loud bird, especially at breeding ground. Most heard is a characteristic "tew-hoo", or "tew-hoo-hoo" with first syllable accentuated. No gap between the syllables like Greenshank, and usually with a marked falling pitch. Song similar to Wood Sandpiper, but with three accented notes in each cycle, not two.
