Appearance:

Unmistakable in most of Europe where no other nuthatch species occur. Only bird climbing head-first downwards trees. Blue-grey upperparts, white underparts and solid black eye stripe. Large head, long bill and short tail. Climbs in jerky, but nimble motion. Scandinavian birds with mostly white underparts (except for vent), continental birds with more rufous belly.

Sound:

Very varied voice. Ranging from very high pitched whistles and melodic resonant calls, to chattering and nasal mocking sounds. Song a simple series of loud notes. Characteristic warning call a hard "check" or "chwit", often in rapid series, like a pebble bouncing on hollow ice.

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.
