Population justification: In Europe, the total population size is estimated at 10,900,000-19,200,000 mature individuals, with 5,490,000-9,570,000 breeding pairs (BirdLife International 2021), and comprises approximately 40% of the species' global range, so a very preliminary estimate of the global population size is between 27,300,000-48,000,000 mature individuals, although further validation of this estimate is desirable. Northern and eastern populations tend to fluctuate in an irregular pattern, possibly tied to variations in the crop of spruce seeds (Harrap 2015). In Europe, the species' population is considered to have remained relatively stable over three generations (10 years) (BirdLife International 2021). Based on these data, and the proportion of the species' global range that this region holds, the global population size is considered to be stable over three generations This species is considered to have a high dependency on forest habitat, which is estimated to be declining at a slow rate within its mapped range (Global Forest Watch 2024).
