Population justification: The global population size has not been quantified, but it is assumed to be relatively common within its large range. It is here tentatively placed in the band 50-150 million mature individuals.
Trend justification: In Europe, trends since 1980 show that populations have undergone a moderate decline, 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).
