Abstract
We obtained 175 blood samples from wild White Storks in Bulgaria, and determined the values of 18 indicators - alanine transaminase, albumin, alkaline phosphatase, amylase, aspartate transaminase, calcium, chloride, cholesterol, creatine kinase, creatinine, blood glucose, lactate dehydrogenase, magnesium, phosphorus, total bilirubin, total protein, triglycerides and uric acid. In this research, we compared those results with regards to the location from which the birds came from - we conditionally separated Bulgaria into four geographical regions, and to their age. We found statistically significant differences in two parameters - albumin, between northwestern and northeastern populations, and creatinine, between northeastern and southeastern populations. There was also a statistically significant difference in the albumin values between juvenile and adult storks, which we found to be decreasing with age.
