性传播疾病（STDS）跨越了性选择理论的两个领域，即多次交配在决定个体生殖成功中的作用，以及寄生虫在配偶选择中的作用，但在生态学文献中相对被忽视。我回顾了性传播疾病在商业饲养的鸟类种群中的发生情况，发现了在这些种群中存在致病性传播疾病的广泛证据。性传播疾病可能对行为、生殖生理和某些第二性征的演变产生重要影响。在性病代价高昂的地方，它们被假设影响了交配系统的进化，并通过女性生殖道中的敌意选择来解释授精后精子的高死亡率。共同进化循环的潜力是巨大的，因为一些性病可能与女性和男性生殖生理学共同进化，这可能本身共同进化。虽然目前关于野鸟中性传播疾病发生的资料很少，但它们的鉴定技术已经很成熟。这项研究提出了一些可检验的预测的后果，性传播疾病的鸟类生殖生物学，我建议，性传播疾病应被视为一个潜在的强大的因素，在未来的研究择偶和精子竞争。
Sexually transmitted diseases (STDS) span two current areas of sexual selection theory, namely the roles of multiple mating in determining individual reproductive success, and of parasites in mate choice, yet have been relatively neglected in the ecological literature. I reviewed the occurrence of STDs in populations of commercially kept birds and found widespread evidence for the existence of pathogenic STDS in such populations. STDs may have important consequences for the evolution of behaviour reproductive physiology and some secondary sexual characteristics. Where STDs are costly they are hypothesized to affect the evolution of mating systems, and, via selection for hostility in the female reproductive tract, to explain high levels of sperm mortality after insemination. The potential for coevolutionary cycling is large, as some STDs may coevolve with female and male reproductive physiology, which may themselves coevolve. Although little information currently exists concerning the occurrence of STDs in wild birds, techniques for their identification are well established. This study raises a number of testable predictions about the consequences of STDs for avian reproductive biology, and I suggest that STDs should be considered as a potentially powerful factor in future studies of mate choice and sperm competition.
