The purpose of this study was to examine the factors affecting common moorhens’ nest site selection and hatching success in Yugu stream, Gongju-si, South Korea. Common moorhens’ nests were found in colonies of Phragmites japonica, Iris pseudoacorus, and Typha angustata; of these, Typha angustata colony turned out to be the most preferred (82.1%). The hatching failure factors of common moorhens were found to be predation (55.6%), flooding (38.9%), and destruction by fishermen (5.6%). The factors affecting common moorhens’ nest site selection turned out to be water depth, vegetation height, distance to open water, and vegetation density. It was found that, with the decrease of water depth and vegetation height, the possibility of nest creation increased; furthermore, with the increase of distance to open water and vegetation density, the possibility of nest creation increased. Except for the nest height, there was no significant difference in the nest site characteristics between breeding nests and trial nests. Nest height of the breeding nest sites was significantly higher than that of the trial nest sites. With the increase of vegetation height, distance to the bank, and nest height, the possibility of breeding nests increased. Successful hatching nests had a significantly higher vegetation density and nest height than failed hatching nests. Vegetation density turned out to affect common moorhens’ hatching success. It seems that, with the increase of vegetation density, common moorhens can more easily hide from predators and thus stay safe.
