共生微生物可以影响宿主的行为和适应性。肠道微生物群得到了最多的研究，而对其他重要的微生物群落，如哺乳动物肛门腺和鸟类尾臀腺等产生气味的腺体的关注较少。然而，越来越多的证据表明，栖息在产生气味的腺体中的微生物通过促进化学信号的变化在动物行为中发挥着重要作用。自由生活和圈养条件通常在社会环境，食物多样性和可用性，疾病暴露和其他因素方面有所不同-所有这些都可以转化为肠道微生物群的差异。然而，是否外在因素，如圈养改变微生物群落的气味腺体仍然是一个悬而未决的问题。我们比较了自由生活和圈养的歌麻雀（Melospiza melodia）的尾臀腺微生物群，并测试了饮食操作对圈养鸟类腺微生物群的影响。正如预测的那样，自由生活和圈养鸟类之间的尾臀腺微生物群显着不同。令人惊讶的是，圈养鸟类的微生物多样性高于自由生活的鸟类，我们发现饮食治疗对圈养鸟类微生物群没有影响。确定导致群体间微生物差异的具体因素，并确定共生微生物群的变化是否会改变行为和适应性，是该领域的重要下一步。
Symbiotic microbes can affect host behavior and fitness. Gut microbiota have received the most study, with less attention to other important microbial communities like those of scent-producing glands such as mammalian anal glands and the avian uropygial gland. However, mounting evidence suggests that microbes inhabiting scent-producing glands play an important role in animal behavior by contributing to variation in chemical signals. Free-living and captive conditions typically differ in social environment, food diversity and availability, disease exposure, and other factors—all of which can translate into differences in gut microbiota. However, whether extrinsic factors such as captivity alter microbial communities in scent glands remains an open question. We compared the uropygial gland microbiota of free-living and captive song sparrows (Melospiza melodia) and tested for an effect of dietary manipulations on the gland microbiota of captive birds. As predicted, the uropygial gland microbiota was significantly different between free-living and captive birds. Surprisingly, microbial diversity was higher in captive than free-living birds, and we found no effect of dietary treatments on captive bird microbiota. Identifying the specific factors responsible for microbial differences among groups and determining whether changes in symbiotic microbiota alter behavior and fitness are important next steps in this field.
