From January. 1996 to January 1997, birds survey was carried out in 4 mangrove wetlands in Fujian. As a result, 92 species, belonging to 55 genera, 27 families, and 13 orders were recorded. Among them, 29 species, 31 52% of the total were passeriformes; 63 species, 68 48% of the total were nonpasseriformes. The survey revealed that the bird communities in Fujian mangrove wetlands had the features as follows:①Nonpasseriformes was more than passeriformes. Wading birds were more abundant in bird communities. ②Farm birds were common and forest birds were scarce. ③Lack of endemic species. ④Winter visitors and passing migrants were dominant in bird communities. ⑤Migrant behaviors varied with species. ⑥Mangrove wetland is important for bird conservation, especially for egrets and migrant wadings.
The paper reported the results of avian survey in the mangrove wetland of Dongzhaigang from 1997 to 1998.It showed that 78 species of birds were recorded,and belong to 12 orders 26 families.Of these birds,35 species and 43 species were migratory birds and resident birds respectively. 9 species were secone class nationaly protected birds;32 species were on the list of China-Japan Agreement for Protection of Migratory Birds;14 species were on the list of China Australia Agreement for Protection of Migratory Birds.The number of bird species varied with seasons.The trends were winter>autumn>spring>summer on upland,respectively.The avian diversity index and evenness index were greater on upland than on mudflat in summer.The avian diversity index was greater and the avian evenness index was less on mudflat than on upland in autumn.The avian diversity index and evenness index were greater on mudflat than upland in winter.
