This study evaluated the health status and established hematologic and serum biochemistry parameters for free-living nestlings of the Hyacinth Macaw (Anodorhynchus hyacinthinus) from the Brazilian Pantanal (19 degrees 51'-19 degrees 58'S; 56 degrees 17'-56 degrees 24'W), for four consecutive years (from December 2003 through December 2006). Physical examinations indicated that all the birds were in good health. Endoparasites and blood parasites were not detected in any of the nestlings, and ectoparasites seemed to be limited to Philornis sp. (Diptera: Muscidae). Significantly higher levels of total white blood cells and heterophils, glucose, total protein, triglycerides, and phosphorus were observed in females. In females, higher cholesterol levels and packed cell volumes were observed in older birds, and total white blood cell and heterophil counts were higher in young animals. In males, uric acid levels were higher in older individuals. Wild Pantanal Hyacinth Macaws feed on only two species of palm nuts (Acrocomia totai and Scheelea phalerta). This limited food habit has a strong impact on population size and may alter the clinical pathology parameters of these birds. Therefore, knowledge of blood levels in normal individuals is essential to assess the physiologic and pathologic condition of wild macaws, to assess the effects of environmental changes on their health, and to contribute to conservation strategies of this endangered species.
本研究连续四年（从2003年12月至2006年12月）评估了来自巴西潘塔纳尔湿地（南纬19°51′-19°58′；西经56°17′-56°24′）的野生紫蓝金刚鹦鹉（Anodorhynchus hyacinthinus）雏鸟的健康状况，并确定了其血液学和血清生化参数。体格检查表明所有鸟类健康状况良好。在任何雏鸟中均未检测到体内寄生虫和血液寄生虫，体外寄生虫似乎仅限于Philornis sp.（双翅目：蝇科）。观察到雌性的总白细胞、嗜异性粒细胞、葡萄糖、总蛋白、甘油三酯和磷水平显著更高。在雌性中，老龄鸟的胆固醇水平和红细胞压积更高，而幼龄动物的总白细胞和嗜异性粒细胞计数更高。在雄性中，老龄个体的尿酸水平更高。野生潘塔纳尔紫蓝金刚鹦鹉仅以两种棕榈坚果（Acrocomia totai和Scheelea phalerta）为食。这种有限的食性对种群数量有很大影响，并可能改变这些鸟类的临床病理参数。因此，了解正常个体的血液水平对于评估野生金刚鹦鹉的生理和病理状况、评估环境变化对其健康的影响以及为这种濒危物种的保护策略做出贡献至关重要。
