Taxonomic note
Normally considered probably closest to A. melanopogon, although genetic data are contradictory on this point (Arbabi et al. 2014, Fregin et al. 2009). Monotypic.

Population justification:
In Europe, the breeding population is estimated to number 9,100-14,300 calling males, which equates to approximately 18,000-29,000 mature individuals and 27,000-43,000 individuals (BirdLife International 2021). The entire breeding population is contained within Europe, with 99% of the population found in Poland, Belarus and Ukraine (the Central European subpopulation), so an estimate of the global population size is 18,000-29,000 mature individuals. Furthermore, previous research from Tanneberger and Kubacka (2018) estimated the global population to be less than 11,000 singing males, while Briedis and Keišs (2016) provided a range of 11,000-16,000 singing males, or 22,000-32,000 mature individuals.Trend justification: The west Siberian population in European Russia is probably extinct, with the last confirmed record in 2000 (Tanneberger and Kubacka 2018). The Hungarian subpopulation collapsed from c. 700 singing males to 331 in 2002, with another collapse in 2006, and a final collapse in 2012 – no singing males have been observed since (Végvári and Flade 2012). There are varying rates of decline across the global range, less than previously observed. While it appears that the large population in Poland is stable or even increasing, the Belarus population declined by 47-55% between 2000-2011 (BirdLife International 2015) and the Pomeranian population has declined to critical levels. The Lithuanian population appears to have recovered since 2013 to 247 s.m. in 2016 (Ž. Morkv?nas in litt. 2016).
In Europe, the population size is estimated to be decreasing by approximately 15% in 10 years (Birdlife International 2021). While the global population appears stable, some subpopulations are declining (Tanneberger and Kubacka 2018) as well as extinction of small peripheral populations (Zmihorski et al. 2016). Fluctuations from large breeding sites, as well as the weakness of counting methods, may also be masking a slow decline. Harmful impacts from pollutants may be an emerging issue, but its impact on the population has not been investigated (Pacyna et al. 2018).
As the majority of the breeding population is contained within Europe, and in the face of possible local extinctions, the global population is inferred to be declining at a rate of 10-19% over 10 years, primarily due to severe habitat degradation.
