Population justification: The global population in 2007-2009 was estimated to number c.44,000 individuals (Wetlands International 2014), which is assumed here to include c.29,500 mature individuals.

Trend justification: Recent evidence suggests that this species declined overall between 1987 and 2011 (Wetlands International 2014), and an estimated decline of 20-29% has occurred in Australia over 25 years, with some variability in local rates and trends (Garnett et al. 2011). At one key wintering site, Eighty Mile Beach in Western Australia, surveys in December 2008 found 7,950 birds, a decline of c.46% since surveys in 1999 and 2001 (Garnett et al. 2011, MacKinnon et al. 2012). Numbers migrating through Japan in autumn have declined since 1978, and by 57% between c.1983 and c.2007 (Amano et al. 2010). At Tubbataha Reefs Natural Park, Palawan, Philippines, the average number of birds counted (based on 5-year intervals since 1999) shows a declining trend from 21 individuals in 1999-2003, to 17 individuals in 2004-2008, falling to just 2 individuals in 2009-2013, and the number of birds observed during autumn dropped from 237 individuals in October 1991, to 65 in September 2000 and to just 8 in October 2006 (A. Jensen in litt. 2014). The loss and degradation of wetlands (including pollution, reclamation, and urban and industrial expansion), disturbance and hunting are the main threats at stopover sites and on the wintering grounds (Garnett et al. 2011). These survey data and the knowledge of threats to the species support the suspicion of an overall decline of at least 25-29% over 17 years (estimate of three generations).
