|Scientific Name:||Corvus corax|
|Species Authority:||Linnaeus, 1758|
|Taxonomic Source(s):||AERC TAC. 2003. AERC TAC Checklist of bird taxa occurring in Western Palearctic region, 15th Draft. Available at: #http://www.aerc.eu/DOCS/Bird_taxa_of _the_WP15.xls#.|
|Red List Category & Criteria:||Least Concern ver 3.1|
|Facilitator/Compiler(s):||Butchart, S., Ekstrom, J. & Symes, A.|
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 increasing, 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.

|Population:||The global population is estimated to number > c.16,000,000 individuals (Rich et al. 2004), while national population estimates include: < c.50 wintering individuals in China; < c.50 wintering individuals in Korea and possibly c.100-10,000 breeding pairs in Russia (Brazil 2009).
Trend Justification: This species has undergone a large and statistically significant increase over the last 40 years in North America (166% increase over 40 years, equating to a 27.7% increase per decade; data from Breeding Bird Survey and/or Christmas Bird Count: Butcher an In Europe, trends since 1980 show that populations have undergone a moderate increase (p<0.01), 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).
|Current Population Trend:||Increasing|
