Appearance:

Most distinct species of the genus. Most similar to Willow Warbler, but with much more contrasting plumage. Upperparts pure green. Throat and upper chest yellow, contrasting with pure white underparts. Distinct and strong yellow supercilium and black eye-stripe. Long primary projection, with primaries reaching middle of relatively short tail. Tertials with pale green fringes. Legs pale yellowish brown. Posture often horizontal with drooping wings.

Sound:

Song distinct. An accelerating series of sharp, metallic "swee-swee-swee-swee". Typically with a staccato beginning. Pitch drops as the speed increases and the syllables fuses into a continuous trill. Often described as the sound of a spinning coin coming to rest on a glass table. Some phrases may be given in an almost even tempo, and may recall Bonelli's Warbler. Alternative (piping) song a series of 4-6 piping, plaintive and descending "pew - pew" calls. Resembles Willow Tit's song, but is softer with each note more evenly pitched. Contact call similar to individual syllables of piping song, but with heavier accent on the ending.

Appearance:

Largely unmistakable. Pale pinkish brown. Wings dark with white and blue patches. Tail black and rump white (conspicuous in flight). Crown speckled in black. Striking black moustache stripe. Flight pattern straight and fluttering like Nutcracker, but tail longer and bill shorter.

Sound:

Large repertoire. Most heard call a short, drawn and very hoarse, raspy sound, often given in quick successions. Also a Buzzard-like, mewing "peeeaaa" (more drawn and less full tone than Siberian Jay). Quiet and varied subsong with mimicry, resembling a small passerine heard from both sexes. Many other social sounds.
