Population justification: In Europe, the breeding population is estimated to number 6,050,000-11,400,000 pairs, which equates to 12,100,000-22,700,000 mature individuals (BirdLife International 2015). Europe forms c.30% of the global range, so a very preliminary estimate of the global population size is 40,000,000-76,000,000 mature individuals, although further validation of this estimate is needed.

Trend justification: Northern and eastern populations tend to fluctuate in an irregular pattern, possibly tied to variations in the crop of spruce seeds (Harrap 2015). In Europe, trends between 1980 and 2013 have been stable (EBCC 2015).
