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:

Unmistakable. Very small, mouselike bird with short rounded wings, short neck and upright tail. Upperparts chestnut brown and finely barred. Underparts light buff. Forages in thick undergrowth and low bushes, crevices and holes for insects. Easily overlooked, but betrays its presence by its big voice. One of the smallest bird in northern Europe.

Sound:

Song surprisingly loud. A high-pitched stream of clear notes resembling Robin and Dunnock in timbre. Differs from those in showing frequent shifts in pitch with much larger register than Dunnock, and by the unique, numerous, interspersed long trills. Warning call a short hard "teck", like banging two rocks together. Often repeated in series when excited to form machine-gun-like "firing".
