Abstract: In order to fully understand the current situation of bird resources in Dongtai, eight field surveys were conducted in the study area from December 2018 to November 2019. The results show that there were 180 species of birds, belonging to 14 orders and 46 families. Among them, 80 species (44.44%) are palaearctic birds, dominating the birds' distribution pattern. 134 species (74.44%) are residents, winter migratory and summer migratory. 5 species (Ciconia boyciana, Platalea minor, Eurynorhynchus pygmeus, Tringa guttifer, Saundersilarus saundersi) are listed in the first category, and 22 species are listed in the second category of the nationally protected wildlife species in China. One species is classified as critically endangered (CR), 3 species as endangered (EN), 2 species as vulnerable (VU) and 5 species as near threatened (NT) by the International Union for Conservation of Nature (IUCN). Most of the IUCN listed key protected wildlife species and the highly endangered species in the study area were found in coastal tidal flats habitats, which means that the coastal tidal flats habitats in the study area should have priority in protection. The related suggestions are put forward for protecting the birds habitats, such as the construction of artificial tidal ditches and offshore shallow ponds, the maintenance of the key bare beach, and the formulation of long-term monitoring scheme. The findings of this research can provide basic data for the management of Tiaozini Wetland and for birds monitoring in Dongtai.
