Population justification: The European population is estimated at 1,930,000–3,120,000 pairs, which equates to 3,860,000–6,240,000 mature individuals (BirdLife International 2021). Europe forms 65% of the global range, so a very preliminary estimate of the global population size is 5,940,000-9,610,000 mature individuals.
 
The European population is declining at a rate of c. 25% over 10 years (BirdLife International 2021) and it is inferred from this and the observation that the threats considered to be driving this reduction are widespread through the range and ongoing, that there is a continuing decline in the global population.

Trend justification: The population is undergoing moderate declines throughout its range, particularly following widespread declines late in the 20th century (Harris and Franklin 2000). Newly collated information indicates that the European population is declining at a rate of c. 25% over 10 years (BirdLife International 2021). This reflects the population decline reported by the Pan-European Common Bird Monitoring Scheme (European Bird Census Council [EBCC] 2018), and the 8.6% range contraction (at 50-km grid scale) since the 1980s reported in the 2nd European Breeding Bird Atlas (Keller et al. 2020). Europe holds c. 65% of the global breeding range, and possibly an even higher proportion of the global population, with Spain alone holding >90% of the total European population (BirdLife International 2021). The species has been declining for many decades and continues to face considerable threats due to habitat degradation from agricultural intensification and afforestation, fires, long-term climatic factors and potentially hunting (although population impacts of hunting on the species are unknown) (Tucker and Heath 1994, Hagemeijer and Blair 1997, Yosef and ISWG International Shrike Working Group 2020). These threats are expected to continue in the future. The species is also considered very local or extinct across some parts of its range and is listed under national threatened categories in many countries (Yosef and ISWG International Shrike Working Group 2020). While population trend data from outside Europe are scarce and standard monitoring is absent throughout much of the species' range (K.A. Boyla in litt. 2022), it is assumed that the global population is likely to be undergoing similar rates of decline to that of the European population, and therefore the rate of population reduction overall is placed within the band of 20-29% over 10 years.
