Population justification: In Europe, the total population size is estimated at 1,590,000-3,420,000 mature individuals, with 798,000-1,710,000 breeding calling males (BirdLife International 2021), and comprises approximately 40% of the species' global range, so a very preliminary estimate of the global population size is between 3,980,000-8,550,000 mature individuals, although further validation of this estimate is desirable. In Europe, the species' population is considered to have undergone a small decline over three generations (16.77 years) (BirdLife International 2021). Considerable range contraction has occurred in the east and west of the species' range, resulting in local extinctions (Madge and McGowan 2002). This species is considered to have a high dependency on forest habitat, which is estimated to be declining at a rate of 9.1% over the past three generations within its mapped range (Global Forest Watch 2024). It is therefore tentatively suspected that this rate of cover loss may have led to a decline of between 1-19% in the species' population size over the same time frame, with a best estimate of reduction of 5-9%. Based on these data, the global population size is considered to be decreasing slowly over three generations.
