Population justification: The global population totals at 4.4 million pairs, roughly equating to 19.0–23.6 million individuals (Newman et al. 2009, Waugh et al. 2013).

Trend justification: There are persistent signs of a current decline in the global population (Brooke 2004). In North America and in New Zealand, the population trends were found to be decreasing (Butcher and Niven 2007, Clucas et al. 2008, Scott et al. 2008). Though the rate of decline of the whole population has not been quantified, moderately rapid population declines are suspected.
