Bean Goose (Anser fabalis)
Blyth's Reed Warbler (Acrocephalus dumetorum)
Orange legs, black and orange bill. Differs from juvenile White-fronted Goose by less contrast between cheeks and base of bill and crown, more prominent pale edges on back feathers, and by bill colour. Has much darker back than Pink-footed Goose (and never greyish). Colour of legs and bill can be surprisingly difficult to judge in unfavourable light. 2 subspecies that may be considered separate species in near future: A.f.rossicus has shorter bill with more extensive black markings than A.f.fabalis.
Sound:Do not call as much as other grey geese. Sounds similar to the lower sounds of Pink-footed goose, with various reedy calls, but harder, less nasal and more of a "sore throat".

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.
