It is known that stress situations (e.g. predation, climatic changes, pathogens) affect the nutritional and immunological individual state. The hematological and biochemical parameters are useful tool to test nutritional and health status in animals. Our objective was to determine the effect of corticosterone (stress hormone in birds) on hematological parameters in Passer domesticus. Thirty two sparrows were exposed to different concentrations of CORT in drinking water (0, 20, 40 and 80 mg/l) for 72 hours emulating a long-term stress situation. The H/L index was used as an indicator of stress in birds. Hematocrit, serum protein profile by native PAGE, and plasma concentration of triglyceride, uric acid, glucose and total proteins were determined. We analyzed the data using a one-way and RM-ANOVA with Tukey post-hoc test (p
