The objective of this study was to determine the generation status of White-breasted Starling based on cranial measurements. The research was done on July 2018 in Kudus and Klaten regencies. Forty four males and 43 females of mature White-breasted Starling. Vernier callipers and recording form of White-breasted Starling were used in this research. Length and wide of head White-breasted Starling were used as variable. The results of measurement were compared with generation status. Descriptive, correlation and regression analysis were used in this research. The result of the research showed highly strong correlation (r = 0.92) for generation status and head wide of male bird; strong correlation (r = 0.70) for generation status and head length of male bird; highly strong correlation (r = 0.88) for generation status and head wide of female bird and Strong correlation (r = 0.74) for generation status head length of female bird. The regression equation was shown between head wide and length as dependent variable and generation status as independent variable of male and female White-breasted Starling, respectively. In conclusion the generation status of White-breasted Starling can be determine based on craniometri. Head wide is the best parameter of craniomateri for determination of generation status.
