Red-breasted Merganser (Mergus serrator)
Blyth's Reed Warbler (Acrocephalus dumetorum)
Noticeably smaller and more slender than Goosander. Bill much thinner, especially at base. Both sexes with more shaggy crest than Goosander. Male: dark head, white collar. Only sawbill with (medium) dark chest. Female differs from Goosander by smooth transition from brown head to grey lower neck, and less contrasting white throat patch. Striking white wing-bars with crossing black stripe visible in flight.
Sound:Female call a harsh "karr karr". Male display sound a three-syllabic, fast, "chi-ka-wee" slightly resembling Goldeneye.

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.
