Taxonomy

Taxonomic note

Lanius excubitor, L. borealis and L. meridionalis (del Hoyo and Collar 2016) were previously lumped as L. excubitor following AOU (1998 and supplements), Cramp et al. (1977-1994), Dowsett and Forbes-Watson (1993) and Sibley and Monroe (1990, 1993).

Population justification: Population estimates from the European Red List of Birds (BirdLife International 2015) total 372,150-656,150 pairs, or 744,300-1,312,300 mature individuals. rounded here to 744,000-1,310,000 mature individuals.

Trend justification: Data from the Spanish national bird monitoring schemes shows a decline of c. 60% in Spain between 1998-2016, however much of that decline took place before 2010, since when the species’ population has fluctuated but remained broadly stable (SEO/BirdLife 2017). Over the last three generations (12 years; 2005-2016), the graph suggests a decline from c.70% of 1998 levels to c.40% of 1998 levels, which equates to a decline of c. 43% over three generations. As Spain holds c. 95% of the global population, the Spanish trend effectively describes the global trend.
