Gull-billed Tern (Gelochelidon nilotica)
Spotted Redshank (Tringa erythropus)
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.

CCUnmistakable in breeding plumage, with all dark/blackish body unique among Tringas. Most birds seen in Europe will probably be in winter- or juvenile plumage, and can then be mistaken for Redshanks. Spotted Redshanks are slimmer, longer legged and more elegant than Redshanks. The supercilium is much more prominent, the bill is slimmer and longer. Most diagnostic is the lack of white wing-bars, and the white sigar-shaped patch on the back. The barring in juveniles reaches from the belly and all the way back to the vent. Often feeds in deeper water than Redshanks, even by swimming and upending.
Sound:Flight call loud and diagnostic, and is often the first sign of the species' presence; a sharp and short, disyllabic "koo-eett", with the first syllable falling in pitch and the second rising sharply. Display call a squeaky, but melodic "krroo-lee-ooo" repeated in cycles. Alarm call a falcon-like "ke-ke-ke-ke".
