Carotenoids are pigmented compounds acquired through diet that have important functions as antioxidants and immune modulators. We studied the association between immunity and circulating carotenoids in Andean condors (Vultur gryphus). We evaluated the relationship between α‐, β‐, and γ‐globulin blood concentrations and different circulating carotenoids in two groups of Andean condors that differ in their mean health status, rehabilitating (suffering different pathologies), and wild individuals (trapped when displaying their physiological behavior). In rehabilitating individuals, α‐, β‐, and γ‐globulin concentrations were higher than in wild individuals. This shows that rehabilitating individuals were developing an immune response associated with the pathologies that they were suffering at the time of sampling. In addition, circulating carotenoids were lower in rehabilitating than in wild individuals. We found negative correlations between α‐, β‐, and γ‐globulins and different circulating carotenoids in rehabilitating individuals, but not in wild condors. Xanthophylls were strongly related to α‐, β‐, and γ‐globulin blood concentrations in rehabilitating, but not in wild condors. Our results suggest that there is a potential relationship between circulating carotenoids and immunity in the Andean condor. Given that this species may display a carotenoid‐based pigmentation, our results could suggest that a trade‐off between the immune system and external coloration could operate in this species, which may have implications in their access to food resources and mate selection and, thus, in their conservation.

禽类清道夫中的血浆类胡萝卜素和免疫力。
类胡萝卜素是通过饮食获得的色素化合物，具有重要的抗氧化剂和免疫调节剂功能。我们研究了安第斯秃鹰（Vultur gryphus）的免疫力与循环类胡萝卜素之间的关联）。我们评估了两组安第斯秃鹰的α-，β-和γ-球蛋白血药浓度与不同循环类胡萝卜素之间的关系，这些秃鹰的平均健康状况不同，康复（遭受不同的病理变化）和野生个体（在展示其时被困）生理行为）。在康复个体中，α-，β-和γ-球蛋白的浓度高于野生个体。这表明，康复个体正在发展与他们在采样时所患病理相关的免疫应答。此外，循环中的类胡萝卜素康复水平低于野生个体。我们发现，在康复个体中，α-，β-和γ-球蛋白与不同循环类胡萝卜素之间呈负相关，而在野生秃鹰中则没有。叶黄素在康复中与α-，β-和γ-球蛋白的血液浓度密切相关，但与野生秃鹰无关。我们的结果表明，在安第斯秃鹰中循环类胡萝卜素与免疫力之间存在潜在的关系。鉴于该物种可能显示出基于类胡萝卜素的色素沉着，我们的结果可能表明，该物种可能在免疫系统和外部色素之间进行权衡，这可能对它们获取食物资源和配偶的选择有影响。 ，在他们的保护下。
