Population justification: In Europe, the total population size is estimated at 23,200,000-38,900,000 mature individuals, with 11,600,000-19,500,000 breeding pairs (BirdLife International 2021), and comprises approximately 80% of the species' global range, so a very preliminary estimate of the global population size is between 29,000,000-48,600,000 mature individuals, although further validation of this estimate is desirable. The species' population in Europe is considered to have undergone a small decline over three generations (12.39 years) (BirdLife International 2021). This species is considered to have a medium dependency on forest habitat, which is estimated to be declining at a slow rate within its mapped range (Global Forest Watch 2024). Accordingly the global population size is considered to be decreasing slowly over three generations.
