Abstract

30 captive Black-chested Buzzard-Eagles Geranoaetus melanoleucus from the Raptors Rehabilitation Center of the Union of Ornithologists of Chile were used to determine blood reference values. Packed cell volume (PCV), total protein plasma (TPP), and total and differential leukocyte counts were measured. Gamma-glutamyl transpeptidase (GGT), lactate dehydrogenase (LDH), alkaline phosphatase (ALP), creatine kinase (CK), creatinine (CRE), calcium (Ca), inorganic phosphorus (P) and uric acid (UA) were analyzed. No significant differences were found between sexes (P> 0.05). No blood parasites were found. The results obtained from this study establish a baseline for hematological and serum biochemistry parameters for the Black-chested Buzzard-Eagles. © 2023 Neotropical Ornithological Society.
