Appearance:

Reedbed-living, dull coloured warbler with fan-shaped tail. Under tail coverts lacking pale fringes or markings. Vague and short supercilium. Differs from other locustella by unstreaked chest, back and under tail coverts. From Reed Warbler and Marsh Warbler by very long and buff under tail coverts, smaller head and pinkish legs.

Sound:

Song insect-like and high-pitched. A monotonous stream of even clicks similar to the whirring of a sewing machine. Song most similar to Grasshopper Warbler but faster (each click hard to distinguish), and lower pitched with less, ringing quality, due to less prominent high frequencies. At closer range a Robin-like, accelerating ticking is heard, introducing the actual song.

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.
