LC
Great Grey Shrike Lanius excubitor

Justification
This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend appears to be stable, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size is extremely large, and hence does not approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.

Taxonomic note
Lanius excubitor (Sibley and Monroe 1990, 1993) was split into L. excubitor, 'Northern Grey Shrike' and L. meridionalis, 'Southern Grey Shrike' (including pallidirostris), by AERC TAC (2003) (Sanster et al. 2002), but this treatment is not followed by the BirdLife Taxonomic Working Group pending further clarification of the relationships between each of them and also other members of the meridionalis group (sensu Lefranc and other authorities).

Population justification
Rich et al. (2004) estimated the global population to number 1,000,000 individuals. In Europe, the breeding population is estimated to number 250,000-400,000 breeding pairs, equating to 750,000-1,200,000 individuals (BirdLife International 2004). Europe forms 5-24% of the global range, so a very preliminary revised estimate of the global population size is 3,130,000-24,000,000 individuals, although further validation of this estimate is needed. The population in Russia has been estimated at c.100-10,000 breeding pairs and c.50-1,000 individuals on migration (Brazil 2009).

Trend justification
This species has had stable population trends over the last 40 years in North America (data from Breeding Bird Survey and/or Christmas Bird Count: Butcher and Niven 2007).
