The aim of this study was to establish hematologic and plasma biochemical reference intervals for clinically healthy cinereous vultures (Aegypius monachus) in a rehabilitation setting before release. Animals used in this study were cinereous vultures hospitalized in a wildlife center located in the province of Gyeongsangnam-do, the Republic of Korea. Blood samples were collected from 31 cinereous vultures before their release between 2011 and 2014 at the Gyeongnam Wildlife Center. Complete blood count and plasma biochemical analyses were performed within 2 hr of the blood sampling. Reference intervals were calculated from the 10th to the 90th percentile, together with the mean, SD, and lowest and highest observed values. The results of this study may be useful in evaluating the physical condition and clinical monitoring of cinereous vultures in captivity before release and contribute to the determination of reference ranges for healthy cinereous vultures.
