In this study, morphological characteristics of peripheral blood cell, and certain hematological and serum biochemistry values were determined in 16 clinical healthy adult common kestrels in order to establish normal reference values for this population. Seven different types of blood cells were determined, such as erythrocytes, thrombocytes, big lymphocytes, monocytes, heterophils, basophils, small lymphocytes. According to the results, hematology of red blood cell counts, white blood cell counts, hemoglobin, packed cell volume, mean corpuscular hemoglobin (MCH), mean cell volume (MCV), mean corpuscular hemoglobin concentration (MCHC) were 2.47±0.55×10¹²/L, 6.02±1.42×10⁹/L , 124.6±16.74g/L, 39.94±3.84%, 523.01±119.49pg, 523.01±119.49fl, 314.29±48.80%. The results showed that serum biochemistry concentration of uric acid, total protein, albumin, alkaline phosphates were 2.22±0.68 nmol/L, 6.94±0.61g/L,4.91±0.44g/L, 10.17±2.93mg%. And, the different counts of leukocytes in the peripheral blood of clinical healthy common kestrel were determined as follows as 49.80±1.03% heterophils, 43.80±5.44% lymphocytes, 1.80±1.48% monocytes, 0.00±0.00% eosinophils, 3.60±1.24% basophils. These hematology and serum biochemistry values can be used as standard profiles for healthy adult common kestrel in captivity .
