Abstract: The Su Tsao Wild Life Reserve is a very imporant perching habitat in southwest Taiwan for migrant birds about 189 species in whih Charadriidae and Scoloplacidae are the most abundant birds. An area with high density birds during the migrant period were chosen as experimental sites from 2000 to 2001. From analyzing the gizzard contents of birds and comparing the invertebrate specimens in these areas and nearby, we suggested that both Charadriidae and Scoloplacidae consumed the similar diets, which are the main benthos here, including the mollusks(Thiara riqueti and Clithon retropictus), polychaetes(Neanthes glandicincta), aquatic insects(Hydrophilidae) and te Diptera larvae and pupas. Statistic analysis presents that the diets of Charadriidae nd Scoloplacidae(expect Charadrius alexandrinus) are limited in which the habitats can provide not by the food preferences of birds and no significant result support the effect of bird consuming to benthos and zooplanktons. In this study we also found that the salt pants are indeed rich in food resources for the migrant birds and Charadrius alexandrinus with special feeding behavior seemed to affect the prey itm they consumed. No such correlation was observed between the abundances of birds and benthos.
