A total of 4,045 individuals of 47 species were observed in the Yeongsan Lake region of Yeongsan River between January and December of 2009. Dominant species, in decreasing order, included the Fulica atra (24.72%, 1,000 individuals), followed by the Larus ridibundus (17.31%, 700 individuals), Larus crassirostris (13.84%, 560 individuals), Mergus merganser (7.29%, 295 individuals), Passer montanus (6.18%, 250 individuals) and the Aythya fuligula (5.34%, 216 individuals). In terms of the total number of species observed per month, November showed the highest number at 23 species and September showed the lowest figure at 9 species. Furthermore, February showed the highest number of individuals at 2,382, and May showed the lowest number at 114 individuals. In relation to species diversity, May, despite being the month with the lowest bird count, showed the highest number of species as well as the highest level of species diversity (H') at 2.37 and species abundance at (Da) 4.22. Conversely, September, which recorded the lowest number of species observed, showed lowest levels of species diversity (H') at 0.37 and species abundance at (Da) 1.26. In terms of the seasons, summer (between July and September) showed the lowest species diversity, while spring and fall, which are migratory periods for migratory birds, showed high level of species diversity. This study observed 3 government protected species.
