The presence of birds is important to verify ecological condition in cities since they respond well to the availability of habitat structure. This study aims at investigating park structures which influence bird species diversity in Putrajaya. The studied areas consist of six metropolitan parks. Vegetation structure and bird species data were collected through distance sampling method. Evaluations of overall 12 points were carried out to be mapped in the Standard Computer-aided Design (CAD) software. The results reveal that park with higher density vegetation supports higher habitat variables including food, foraging substrate and nesting site for birds to survive in Putrajaya.
