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:

Glossy black hood and plain, pale brown upperparts. Cheeks brownish towards nape. Small, rounded, black bib. Small pale spot on base of upper mandible (often surprisingly visible, despite small size). Very similar to Willow Tit, especially British sub.sp. Willow tit has bigger head, not so glossy cap, whiter cheeks, larger bib and pale wing panel.

Sound:

Most easily identified by sound. Especially in areas where plumage is less distinct compared to Willow Tit, like in Britain. Most typical call an explosive, sneeze-like "pee-choo", starting high-pitched and ending on a lower note.

Also calls "chaa chaa chaa" but not so nasal and drawn-out as willow tit. Song: A simple one or two note call repeated in series. Usually rising slightly in pitch, and with a "liquid" quality. Sometimes also a ringing, vibrating song. Generally has a much sharper tone than the soft song of willow tit. Other calls: Various high pitched sound. Often quite explosive.
