LC
Eurasian Magpie Pica pica



Justification

Justification of Red List Category
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 has not been quantified but must be extremely large, and it therefore does not approach the thresholds for Vulnerable (<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.

Population justification
In Europe, the breeding population is estimated to number 7,500,000-19,000,000 breeding pairs, equating to 22,500,000-57,000,000 individuals (BirdLife International 2004). National population estimates include: c.10,000-100,000 breeding pairs in China; c.100-100,000 introduced breeding pairs in Taiwan; c.10,000-100,000 breeding pairs in Korea; c.100-10,000 breeding pairs (possibly introduced) in Japan and c.10,000-100,000 breeding pairs in Russia (Brazil 2009).

Trend justification
In Europe, trends since 1980 have been stable, based on provisional data for 21 countries from the Pan-European Common Bird Monitoring Scheme (EBCC/RSPB/BirdLife/Statistics Netherlands; P. Vorisek in litt. 2008).
