The purpose of this study was to determine the population and the distribution pattern of Greater egret (E. Alba). The methods used in the three locations are Line Transect method, GIS method, and Literature method. The research analysis using population prediction, total population and bird distribution pattern with Morisita Index. Results of the study with a total of 1620 minute studies found greater egret (E. Alba) on field locations 64 frequency, at pond location 66 frequency and at mangrove forest 8 frequency, so the total encounter of greater egret (E. Alba) are 138 frequency.
