Black cockatoos in southwest Western Australia face population declines as a result of habitat loss and fragmentation, poaching, competition with other species, vehicle strikes, and shootings. In this study, hematologic and plasma biochemical reference values were determined for 3 endemic Western Australian black cockatoo species: Carnaby's cockatoo (Calyptorhynchus latirostris) (n = 34), Baudin's cockatoo (Calyptorhynchus baudinii) (n = 22), and forest red-tailed black cockatoo (Calyptorhynchus banksii naso) (n = 22). Significant sex-related differences were detected in Carnaby's cockatoos, and differences were also found among the 3 species. The forest red-tailed black cockatoos showed a markedly greater eosinophil count than did the 2 white-tailed species. Blood values from samples obtained by different collection methods differed significantly for Carnaby's cockatoos, which indicates that anesthesia may affect analyte values and that collection methods should remain consistent. The results of this study will be useful for clinically evaluating wild black cockatoos that are undergoing rehabilitation for release and will provide baseline data for future investigations of free-living black cockatoo health.
由于栖息地丧失和破碎化、偷猎、与其他物种的竞争、车辆撞击及枪击，澳大利亚西南部的黑凤头鹦鹉面临种群数量下降的问题。在本研究中，测定了3种西澳大利亚特有的黑凤头鹦鹉的血液学和血浆生化参考值：卡纳比凤头鹦鹉（Calyptorhynchus latirostris）（n = 34）、鲍丁凤头鹦鹉（Calyptorhynchus baudinii）（n = 22）和森林红尾黑凤头鹦鹉（Calyptorhynchus banksii naso）（n = 22）。在卡纳比凤头鹦鹉中检测到显著的性别相关差异，且在这3个物种之间也发现了差异。森林红尾黑凤头鹦鹉的嗜酸性粒细胞计数明显高于另外两种白尾凤头鹦鹉。对于卡纳比凤头鹦鹉，通过不同采集方法获得的样本的血液值存在显著差异，这表明麻醉可能会影响分析物值，采集方法应保持一致。本研究结果将有助于对正在接受康复训练以便放归的野生黑凤头鹦鹉进行临床评估，并为未来对自由生活的黑凤头鹦鹉健康状况的调查提供基线数据。
