The green-naped lorikeet (Trichoglossus haematodus haematodus) is a small, brightly colored psittacine that is one of many subspecies of the rainbow lorikeet popular in captivity. Overall, the rainbow lorikeet population is declining but the wide range of subspecies means the population is classified as “least concern” by the International Union for Conservation of Nature. The goal of this study was to establish normal hematologic and plasma biochemical analyte reference intervals for juvenile green-naped lorikeets. Hematology and plasma biochemistry variables were determined for 102 clinically healthy, captive-born, juvenile (2–6 mo) green-naped lorikeets house at a single institution. This study is the first report for hematologic and plasma biochemical values for any Trichoglossus species.
