From April 2002 to December 2003, the blackfaced spoonbills were investigated in Dongtan Wetland in Chongming Island of Shanghai, China. Results showed that the species were recorded in Dongtan mostly during the northward migrant. They prefer crab ponds as their feeding and resting sites. The blackfaced spoonbill is very rarely in winter. In the spring of 2002, the species stayed in Dongtan at a flock of 45~16 individuals; but in the spring of 2003, each flock was less than 30 individuals and the total amount recorded there is about 130. This showed the Dongtan Wetland has become one of the important overstop areas of blackfaced spoonbills during their migration.
