Little Bittern (Ixobrychus minutus)
Blyth's Reed Warbler (Acrocephalus dumetorum)
Usually recognizable by size alone. Distinctly smaller than any congener. Pale wing-panel formed by inner coverts is striking in all plumages, especially in flight. Male with contrasting black and white/buff plumage. Female with dark, but pale fringed back and streaked throat. Immature with streaked, bittern-like plumage, and wing-panel is brown-spotted. Skulky behaviour, and most active at dusk or after dark. Mostly seen in flight when crossing open water. Flight action rapid and clipping, and landing is preceded by short glide.
Sound:Mostly silent except in breeding season. Song is a series of short, deep, frog-like "gorrk", repeated every 2 seconds. Tone is muffled and hollow, but far-carrying. Flight-call a sharp "ki-ke-ke" or a nasal "ke".

Similar to Reed Warbler but note very short primary projection, evenly coloured wings with dull tertials. Under tail-coverts almost white, with very little buff tinge. Legs overall darker than congeners. Immature birds with slightly paler legs and warmer upperparts and fringes to flight-feathers. Leaves a slimmer impression than Reed- and Marsh W., with flatter forehead and tapering bill. Posture often Sylvia-like with frequent cocking, flicking and fanning of tail.
Sound:Contact call a short and sharp Lesser Whitethroat-like "tek", different from Mars W. Alarm call a dry, rolling "krrrreet", often with a register break splitting into high register overtones. Song recalls Marsh Warbler in timbre but is generally diagnostic. Tempo slow and deliberate, pace recalling that of Song Thrush, with marked pauses. Typical articulate, arpeggio-like whistling motifs alternated by mimicry are often repeated many times. Daytime song less typical than normal song at night, with faster pace and less repetition.
