RESUMO
This work described and compared the hematological findings of 25 clinically healthy Harris's hawks (Parabuteo unicinctus) in captivity at two different tropical locations: 16 samples from Aguascalientes, which altitude is 1878 mean sea level, and nine samples from Amecameca which altitude is 2650 mean sea level. Blood samples were collected from the brachial vein of each raptor under physical restraint. Significant differences between the two locations were found in some parameters including total, erythrocytes, heterophils, basophils, lymphocytes, and heterophil/lymphocyte ratio. When the results were compared to the reference values, the population of Amecameca showed decreased values of hematocrit (32.21 ± 13.72%), hemoglobin (107.40 ± 45.60 g L-1) and erythrocytes (1.98 ± 0.63 ×1012 per µL). This work contributed to the knowledge of variations in blood parameters of clinically healthy captive Harris`s hawks at different tropical locations and sex. The information will enable clinicians to provide appropriate veterinary diagnostics and care to ensure the health and welfare of raptors kept in captivity.
