Population justification: Brooke (2004) estimated the global population to number > c.23,000,000 individuals, while national population estimates include: < c.1,000 individuals on migration in Taiwan; >c.1,000 individuals on migration in Japan and >c.1,000 individuals on migration in Russia (Brazil 2009).
Trend justification: Although the population trend is increasing in North America (based on BBS/CBC data: Butcher and Niven 2007), the global population is suspected to be in decline owing to ecosystem changes resulting from climate change (Brooke 2004).
