Great Reed Warbler (Acrocephalus arundinaceus)
Sandwich Tern (Thalasseus sandvicensis)
Large and bulky warbler with long tail, heavy, thrush-like bill and relatively strong facial markings. Supercilium broad and strong and continues behind eye. Lores dark. Primary projection same length as tertials. Flanks warm beige. Crest often raised. Flight heavy and jerky, and birds are also much more detectable by moving reeds when foraging about in vegetation than congeners. In the Middle East be aware of confusion species Clamorous Reed Warbler and Basra Reed Warbler.
Sound:Contact call a grating, dry "kirrrat", where each rolling r is discernable. Song similar to Reed Warbler in timbre, but much deeper and slower. Fairly concise motifs typically consisting of two deep mono- or disyllabic notes followed by a few higher tones. I.e: "kerek kerek, trii trii trii". Clamorous Reed Warbler differs in more diffuse motifs.

CCSound recording:Recorded by Edmunds Racinskis
Large tern with black bill, with yellow tip (adults). Bill all black in juveniles. Long black cap and shaggy crest. Generally leaves a much whiter impression than other terns in the region (except Roseate Tern). Adult summer: Yellow bill-tip. Tail pure white, and upperparts pale grey. Outer primaries darker than rest of wing, and contrast increases in worn plumage. Broad white trailing edge to inner wing. Underside of primaries with faint narrow dark trailing edge. Forehead white in adult winter and first winter plumage. Juveniles: scaly upperparts and dark bill. Less evenly coloured than juvenile Gull-billed Tern. First winter birds similar to juveniles, but back purer grey and bill shorter. Can be mistaken for Gull-billed Tern, but note different profile. Flight powerful with evenly narrow wings and a front-heavy appearance, due to the long head and bill. Often dives from high above the surface and stays under water longer than Common and Arctic T.
Sound:Contact call a sharp and grating "keeree-eek". Often compared to the pressing of amalgam into a tooth.
