The study was performed for birds living around Junam Reservoir, a representing place for migrant birds in Korea for 10 times from February to December (except November) in 2011. The result states that a total of 11,742 individuals, 102 species, 41 families and 13 orders of birds were found around the reservoir and anseriformes including Anser albifrons (16.42%), Anser fabalis (14.44%), Fulica atra (14.08%), Anas platyrhynchos (10.01%), Anas clypeata (7.70%), Aythya ferina (6.88%) and Anas poecilorhyncha (6.59%) are dominant species. By seasons, winter shows high frequencies of types, number of species, number of individuals and diversity. The result of comparing individuals of swans from 1989 to 2011 shows large fluctuation of individuals, irregular repetition and the number of individuals gradually decreases. The number of geese, dabbling ducks and diving ducks between 1999 and 2011 shows gradual increase. Number of species and individuals of birds in the Junam Reservoir have increased and it is estimated that about between 12,000 and 14,000 individuals of 60~65 species spend winter. The reservoir is important as a habitat for migratory birds, as well as ecological study. It requires administrative supports to provide stable environment for birds to spend winter.
