Appearance:

Easily distinguished from Cormorant in breeding plumage, but at other times easily confused with congeners. Smaller than Cormorant, with a more slender neck and rounded head. Bill slender and straight. Steep forehead with peaked front crown, differs from the wedge shaped head of Cormorant. Bill often with yellow tinge (never in Cormorant). Flies with quicker wing-beats and straight neck (Cormorant with bulge). Often dives with a high jump. Juveniles with darker underparts than Cormorant, and often an obvious brownish tinge. Rare in brackish water.

Sound:

Very deep and harsh voice heard at breeding ground. Deep grunts alternated, or ended with clicking sounds.

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".
