The ecological study of birds in mangrove forest, Samut Prakan province, conducted during July 1983 to September 1984 for 15 months, revealed that 84 bird species in 54 genera, 31 families and 10 orders inhabiting the study area. The highest species, 57 was recorded in November while the lowest species, 19 in May. The mangrove birds obviously showed the close relationship to the annual rainfall and temperature by the number increment took place with the greater amount of rainfall and less amount of temperature; whereas the tide showed distinct effects to the waders. Two types of foraging activities were observed; the vertical pattern was related to the tree heights and the dominating preys were insects (notably soldier flies and beetles) and spiders, while the horizontal one comprising those forage in the open shores, mudflats and water for dominating preys as shrimps, mollusk, crabs and various fishes. The latter showed some relationship within the group which shares the same foraging area, including the competition for food during the drought. About six birds were found to nest in the area during March to July, of which only one, the fly-eater utilized the mangroves both as the foraging and nesting sites
