This study was conducted to investigate the characteristics of waterfowls communities by point-count methods from December 2007 to February 2008 at seven lagoons located in eastern sea shores. We mapped the distribution pattern of waterfowls at the grid size of 30 × 30 meters and compared the area and patton’s diversity index with the characteristics of waterfowls’ communities. We suggest the two factors like density of Greater Scaup and the ratio of dabbling and diving ducks as characteristics of waterfowls at lagoons. Three lagoons like Gwangpo, Maeho and Hyangho showed the low values of above two factors. Patton’s index was a good predictor of species richness of waterfowls and size and perimeter length of lagoon was a good predictor of species richness.
