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:

Adults in summer at close range unmistakable. Bill in juveniles almost black, and much less deep than in adults. Adults in winter plumage also show much darker bill and cheeks than in summer. At a distance head gives an all dark impression, with characteristic dark "shadow " in front of the eye. Head and bill less elongated than in other auks. Wings rounded with dark undersides. "Thighs" dark. Flight fluttering and energic, with shifting weight and angle.

Sound:

Deep, but not so coarse as Razorbill. Smoother and more gliding changes in pitch, like a "slow-motion" laugh or distant chainsaw; "aaaahrrr, aahr, ahr arh".
