Diets of Black-faced Spoonbill (Platalea minor) were mainly fish and shrimps. Survey on species of fish and shrimps in the feeding habitat of the spoonbill would be helpful to analyze the potential prey of this endangered species. Xinhua Bay in Fujian province is one of the most important wintering sites of Black-faced Spoonbill in mainland China. Wintered Black-faced Spoonbills in Xinhua Bay usually rest at the aquaculture ponds in day time,while feed at the intertidal mudflats which are about 8 km away from the farm at night. Forty two species of fish and 6 species of shrimps were collected in the feeding sites. According to the body size, habit,distribution habitat and number of them,19 species of fish and 6 species of shrimps would be the potential prey of Black-faced Spoonbill,with Mugilidae being the most important food resource. The protection of fish and shrimps in intertidal mudflats should be done to promote the conservation of Black-faced Spoonbill.
