Taxonomic note
Aegithalos caudatus and A. glaucogularis (del Hoyo and Collar 2016) were previously lumped as A. caudatus following AERC TAC (2003), Cramp et al. (1977-1994) and Sibley & Monroe (1990, 1993).

Population justification: In Europe, the breeding population is estimated to number 8,310,000-15,000,000 pairs, which equates to 16,600,000-30,100,000 mature individuals (BirdLife International 2015). Europe forms c.40% of the global range, so a very preliminary estimate of the global population size is 41,500,000-75,250,000 mature individuals, although further validation of this estimate is needed. National population estimates include: c.10,000-100,000 breeding pairs in China; c.10,000-100,000 breeding pairs in Korea; c.10,000-100,000 breeding pairs in Japan and c.10,000-100,000 breeding pairs in Russia (Brazil 2009).

Trend justification: The population is suspected to be fluctuating owing to the effects of severe winters and recorded range expansions and regional declines in recent decades (Harrap and Quinn 1996). In Europe, trends between 1980 and 2013 show that the population is stable (EBCC 2015).
