Changes in distribution and abundance of Black-faced Spoonbills (Platalea minor) counted at internationally important sites in 2004, 2010, 2015 and 2020. a January 2004 (four internationally important sites, including two with 1%–5% of the average of the 2016–2020 wintering counts, 40–200, and two with > 5%, 200). b January 2010 (seven internationally important sites, including five with 1%–5% of birds counted, 40–200, and two with > 5%, 200). c January 2015 (nine internationally important sites, including six with 1–5% of birds counted, 40–200, and three with > 5%, 200). d January 2020 (fourteen internationally important sites, including ten with 1%–5% of birds counted, 40–200, and four with > 5%, 200). In recent years, there has been a rapid increase in wintering numbers on the Min and Yangtze River Deltas. Black circles indicate sites that were visited, but where no Black-faced Spoonbills were present. The size of the red circles indicates the numbers counted as a proportion of individuals, in relation to the total wintering numbers counted in 2020
