Category of conservation concern (IUCN, 2020) – Least Concern
Population size: 200 000 – 600 000 pairs
Distributed in most of the country, more densely in mountainous and semi-mountainous forest areas.

Absent or with isolated breeding sites in areas dominated by crops and insignificant woody vegetation.
Comparative distribution of the species compared to the first breeding birds atlas (Iankov, 2007): Breeding locality until 2007 | Breeding locality until 2007, confirmed after 2015 – | New breeding locality after 2015. – The breeding localities after 2015 are identified on a base of raw data from smartbirds.org.
Breeds mainly in forests and is most numerous in broad-leaved deciduous forests. Large numbers are also found in mixed forests, and often – in coniferous forests (especially located at lower altitudes), in alluvial and riverine forests and brush, and often in artificial plantations.
