Range Description

This species breeds in eastern Russia, from the upper reaches of the Nizhnyaya Tunguska river east though the Verkhoyarsk mountains to Kamchatka, and south to Primorye and north-eastern Mongolia (del Hoyo et al. 1996). The Yellow Sea of North Korea, South Korea and China is a particularly important stopover site on migration. It has been recorded as a passage migrant in Japan, Brunei, Bangladesh, Thailand, Viet Nam, Philippines, Malaysia and Singapore, with most birds wintering in Australia, but also in China, Indonesia, Papua New Guinea, and New Zealand (del Hoyo et al. 1996). The global population has recently been estimated at 32,000 individuals (Wetlands International 2015), including 28,000 in Australia (Bamford et al. 2008). The global population is declining, as indicated by reduced numbers at stopover points in South Korea and Japan, and a rapid decline in the number of non-breeding individuals wintering around Australia and New Zealand (Amano 2006, Gosbell and Clemens 2006, Moores et al. in litt. 2008, D. Rogers et al. in litt. 2009, Wilson et al. 2011, Studds et al. in prep.).
