Xinghua Bay in Fujian Province is one of the most important wintering sites of Black-faced Spoonbill （Platalea minor） in mainland China. About 40 to 60 birds estimated wintered in Jiangjing Huaqiao Farm in northeast of Xinghua Bay for 4 years from 2005 to 2008. The most population size was recorded in the winter 2007. The Spoonbills formed group and mainly inhabited in aquaculture ponds around 320 hm² in size. Among the 7 major behavior types, resting was most frequent recorded （80%）, maintenance was around 10%, while other behavior type, such as "foraging", were very low. It indicated that aquaculture ponds were the important rest site of Spoonbills in daytime. As a crucial stopover of Black-faced Spoonbill, the bird migrated to south in the period from November 3^rd to December 12^th in 2007, and left for north from March 8^th to April 20^th in 2008. The number of birds stopped off was about 136 in autumn migration and 226 in spring migration. Individuals with breeding plumage were over 60% of the whole population in spring migration period. We suggest that manage the intertidal mudflats and artificial aquaculture ponds of Xinghua Bay scientifically to promote the conservation for Black-faced Spoonbill.
