Its range covers the vast taiga zone from Scandinavia to Siberia E of Baikal Lake as well as a discontinuous mountain-based distribution in C & S Europe and Scotland. Fennoscandia and Russia are the European strongholds. it is mainly resident, often with local movements in response to feeding requirements with occasional, irruptive long-distance movements (de Juana & Kirwan 2020).
