Hematological and blood biochemistry values are useful in assessing the physiological, nutritional, and overall health status of captive and free-living wildlife. For the chimango caracara (), the most common raptor species in Argentina, reference intervals (RIs) for hematology and blood biochemistry are lacking. For this study, 86 chimango caracaras were captured and studied in Mar del Plata and neighboring areas (Buenos Aires, Argentina) during winter (April-July) in 2018 and 2019. This is the first study to present RIs for 33 blood parameters in a large number of free-living chimango caracaras during the nonbreeding season. In addition, the variability of blood parameters according to sex and calendar year was analyzed. Overall, values for the studied parameters were similar to those described for other raptor species. There were significant differences between years for absolute monocyte counts, relative eosinophils, monocyte counts, glucose, phosphorus, and alanine aminotransferase. Only the relative count of eosinophils, aspartate aminotransferase, and calcium showed significant differences between the sexes. The values of absolute monocyte counts and the relative count of eosinophils and monocytes, glucose, phosphorus, and alanine aminotransferase were higher in 2019 than in 2018, whereas mean corpuscular hemoglobin and mean corpuscular hemoglobin concentration were higher in 2018. Relative eosinophil counts were higher for males than for females, and aspartate aminotransferase activity and calcium concentration were significantly higher for females than for males. The RIs for hematology and plasma biochemistry from this large number of chimango caracaras is of clinical relevance not only for chimango caracaras under medical care in rehabilitation centers but also in ecological studies aimed to investigate the physiological responses of this species to natural and anthropogenic changes.
血液学和血液生化学值可用于评估圈养和野生动物的生理、营养和整体健康状况。对于阿根廷最常见的猛禽 chimango 卡拉卡拉（）来说，缺乏血液学和血液生化学的参考区间（RIs）。在这项研究中，2018 年和 2019 年冬季（4 月至 7 月）在马德普拉塔和邻近地区（阿根廷布宜诺斯艾利斯）捕获并研究了 86 只 chimango 卡拉卡拉。这是首次在非繁殖季节对大量自由生活的 chimango 卡拉卡拉进行 33 项血液参数 RI 研究。此外，还分析了血液参数根据性别和日历年度的变化。总的来说，研究参数的值与其他猛禽物种描述的值相似。绝对单核细胞计数、相对嗜酸性粒细胞、单核细胞计数、葡萄糖、磷和丙氨酸氨基转移酶在年与年之间存在显著差异。只有相对嗜酸性粒细胞计数、天冬氨酸氨基转移酶和钙在性别之间存在显著差异。2019 年的绝对单核细胞计数和相对嗜酸性粒细胞、单核细胞计数、葡萄糖、磷和丙氨酸氨基转移酶的值高于 2018 年，而 2018 年的平均红细胞血红蛋白和平均红细胞血红蛋白浓度较高。雄性的相对嗜酸性粒细胞计数高于雌性，天冬氨酸氨基转移酶活性和钙浓度雌性明显高于雄性。大量 chimango 卡拉卡拉的血液学和血浆生化学 RI 不仅对康复中心接受医疗护理的 chimango 卡拉卡拉具有临床意义，而且对旨在研究该物种对自然和人为变化的生理反应的生态研究也具有临床意义。
