Appearance:

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.

Appearance:

Plain and characterless warbler with secretive behaviour. Larger than Sedge Warbler, with larger wings, broader tail and tail-base. Very similar to Marsh Warbler, and very hard to distinguish by plumage alone. Rump of Reed warbler warm rufous brown, warm buff flanks (yellowish tinge in Marsh Warbler), and slightly longer and more pointed bill. Differs from Blyth's Reed Warbler by longer primary projection, yellowish lower mandible and paler legs. Juveniles especially hard to identify, because of even fainter plumage field marks. Attached to reed beds.

Sound:

By far easiest to identify by song: Characteristic, almost metric and even rhythm, very different from Sedge Warbler. Squeaky timbre with many, almost bizarre, harmonics. Phrases generally repeated 2-3 times. Alarm call a harsh, dry and rolling "kraaaat".
