The adult male  is 14 cm  long with 22.5–27 cm wingspan.It weighs 17–28 g. 

The Eurasian nuthatch calls frequently, usually with a loud, sharp dwip normally repeated twice, sometimes more often if excited. It has a shrill sirrrr or tsi-si-si alarm call, and a thin tsit pre-flight call. The song is a slow whistled pee-pee-pee with many variants, including a faster version, and may be intermingled with the call.

The nest is in a tree cavity, usually an old woodpecker hole, but sometimes of natural origin. Occasionally the female will enlarge an existing hole in rotten wood.

Frequently seen in the Plungė park.
