Appearance:

Combination of striking black and white head and yellow underparts makes it rather unmistakable. Back greenish, tail and wings bluish. Outer tail feathers white. Sexes alike except for wider black belly-stripe in males. Biggest tit.

Sound:

Song highly variable, but usually consisting of two to three notes repeated in a motif. Same birds have many different motifs but generally repeat them many times before switching. Identified by its timbre and often metallic resonant quality, more than by actual phrasing (which is very variable). Often includes buzzing sounds in song. Generally more full-bodied and resonant calls than blue tit, and not so high-pitched. Characteristic Chaffinch-like "tink tink tink" often uttered by male.

Appearance:

Very similar to Marsh Tit, but cheeks whiter, head bigger, and upperparts greyer with white wing-panel. Black bib wider and bigger than in Marsh Tit. Lacks white spot at base of upper mandible. Willow Tits in Great Britain are warmer brown and are more difficult to separate from Marsh Tit.

Sound:

Call: Most characteristic call a frequently uttered, nasal "ti ti chaa chaa chaa". First notes high pitched and the following lower, coarse, nasal and drawn. Sometimes uttered without the introductory high pitched notes. Song: One or two soft, clear, melancholic notes repeated in a slow, even rhythm. At first rising slightly in pitch, then gradually falling. In some areas song is evenly pitched. Other sounds: high pitced "zi zi" similar to other tits.
