Blyth's Reed Warbler (Acrocephalus dumetorum)
Siskin (Spinus spinus)
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.

CCSound recording:Recorded by Edmunds Racinskis
Small green and yellow finch with contrasting dark wings and tail. Underparts whitish with grey streaking. Secondaries, inner primaries and outer tail feathers with yellow base. Relatively long and pointed bill as opposed to Serin. Male distinct with black crown and bib, bright yellow chest, throat and hind-cheeks. Female less contrasty, with more prominent streaking. Juveniles paler and duller than adults, with even heavier streaking than females.
Sound:Distinct calls and song. Most often heard is the sharp and disyllabic contact call: "doo-lee", with both notes descending. Sometimes given a in monosyllabic manner "dlyy". The contact call is also prominent in the improvised song. Other typical sounds in the song includes a peculiar wheeze, like someone sucking their teeth, and lots of expert mimicry.
