Mean(sd), median, minimum and maximum values and number of reference samples used to determine RI (n) are included. When less than 20 reference samples were available, only descriptives are presented. PCV haematocrit, RBC red blood cell count, MCV mean cell volume, MCH mean corpuscular haemoglobin, MCHC mean corpuscular haemoglobin concentration, WBC white blood cell count, H/L ratio Heterophils/Lymphocytes ratio. Results of U Test (p value) a: Differences between wild and captive nestlings, b: Differences between nestlings and adults \(p< 0.001^{***}, p< 0.005^{**}, p< 0.05^{*}\)
