总血血红蛋白浓度越来越多地被用于评估野生鸟类的生理状况，尽管其稳健性尚未在广泛的鸟类分类群中得到明确评估。本文综述了血红蛋白浓度在评估鸟类生理状况方面的可靠性，以及血红蛋白浓度与健康和个体素质的各种组成部分之间的关系。总血血红蛋白浓度越来越多地被用于评估野生鸟类的生理状况，尽管还没有明确认识到这个参数反映个体素质的不同组成部分的可靠性。因此，我回顾了120多项已发表的研究，这些研究将血红蛋白浓度的变化与不同的条件和其他表型或生态特征联系起来。在大多数被研究的鸟类中，血红蛋白浓度与其他常用的状况指标（如体重和脂肪负荷）以及饮食质量呈正相关。此外，雏鸡血红蛋白浓度可靠地反映了寄生节肢动物侵染巢穴的强度，血红蛋白被认为比红细胞压积更准确地反映了噬血体外寄生虫的寄生情况。还有一些证据表明，蠕虫对成年鸟类的血红蛋白水平有负面影响。最后，血红蛋白浓度被发现与诸如到达繁殖地的时间、繁殖时间、卵的大小、发育稳定性和栖息地质量等与适应性相关的特征相关，尽管这些关系在物种之间并不总是一致的。因此，我建议将血液中血红蛋白的总浓度作为鸟类生理状况的一个相对可靠的指标，尽管这个参数也受到年龄、季节和蜕皮过程的强烈影响。因此，建议研究人员在对鸟类进行实验和实地研究时，在使用血红蛋白浓度作为生理状况的代表时，充分控制这些混淆效应。
Total blood hemoglobin concentration is increasingly often used to assess physiological condition in wild birds, although its robustness has not been explicitly evaluated over a wide range of avian taxa. This review summarizes how reliable is hemoglobin concentration in assessing physiological condition and how it is related to various components of fitness and individual quality in birds. Total blood haemoglobin concentration is increasingly being used to assess physiological condition in wild birds, although it has not been explicitly recognized how reliably this parameter reflects different components of individual quality. Thus, I reviewed over 120 published studies linking variation in haemoglobin concentrations to different measures of condition and other phenotypic or ecological traits. In most of the studied avian species, haemoglobin concentrations were positively correlated with other commonly used indices of condition, such as body mass and fat loads, as well as with quality of the diet. Also, chick haemoglobin concentrations reliably reflected the intensity of nest infestation by parasitic arthropods, and haemoglobin was suggested to reflect parasitism by haematophagous ectoparasites much more precisely than haematocrit. There was also some evidence for the negative effect of helminths on haemoglobin levels in adult birds. Finally, haemoglobin concentrations were found to correlate with such fitness-related traits as timing of arrival at breeding grounds, timing of breeding, egg size, developmental stability and habitat quality, although these relationships were not always consistent between species. In consequence, I recommend the total blood haemoglobin concentration as a relatively robust indicator of physiological condition in birds, although this parameter is also strongly affected by age, season and the process of moult. Thus, researchers are advised to control fully for these confounding effects while using haemoglobin concentrations as a proxy of physiological condition in both experimental and field studies on birds.
