Notes

  • S4148 - 415: 20,001 recorded by AWC in 1997. 45: 16,937 counted in Lower Yangtze Valley in 2004. 257: 3,000 migrate through the Kamchatka Peninsula in spring.
  • S7841 - Recent surveys in Yangtze in China have found only c.21,000 individuals, mostly confined to East Dongting Lake National Nature Reserve (Cao et al .2008, Xin Wang et al. 2012). Careful monitoring research has found a small population (<125) in Japan each year (max number) 1999-2000 - 35; 2000-2001 - 41; 2001-2002- 45; 2002-2003- 6; 2003-2004- 70; 2004-2005 - 95; 2005-2006 - 72; 2006-2007 - 83; 2007-2008 - 124; 2008-2009 - 98. Small numbers (<100) are observed annually in Korea (Moores, N. in litt 2012).
