Black-faced Spoonbill (Platalea minor) is listed as the global endangered species. Haifeng Avian Natural Reserve, Guangdong, China, an important congregation site for this species, was newly discovered. It has great significance in the conservation of Black-faced Spoonbill. We conducted 4 censuses on the wintering population for the Black-faced Spoonbills in March 2004 and January 2005, 2006 and 2007 since the species was recorded. The wintering population size increased year by year (from 27 ind. to 72 ind.) and this population was accounted from 2.2% of the global wintering population to 4.1%. The wintering population was recorded in three habitats, mangrove, intertidal mudflat, and manmade shrimp pond. The individuals recorded accumulatively in intertidal mudflat was up to 217 ind., the most birds accounted among the three habitats; the largest flock included 52 birds noted in manmade shrimp pond. Thus, we should take more effective measures to conserve this wintering population and their habitats.
