摘　　要：单配制鸟类的婚外交配行为在自然界中十分常见,自上世纪70年代以来,这一行为的发生机制一直是生态学家研究的热点。诸多学者对导致婚外交配行为发生的因素进行了各种解释,其中不乏对生态因素的探讨。本文在过去近40年关于婚外交配相关研究的基础上,主要介绍了鸟类婚外交配的适应性原因以及纬度、气候和栖息地的复杂性等大规模生态因素对婚外交配行为的影响,并提出一些在研究中出现问题以及对未来研究的展望。Extra-pair copulation is quite normal among socially monogamous species in our nature, the mechanism of this behavior has been a hot area of research for ecologists since the 1970s. Many researchers try to explain the factors that cause the behavior of extra-pair copulation, a large amount of these studies focus on the ecological factors. Base on the relative researches about extra-pair copulation in the past 40 years, this paper introduced the adaption of the extra-pair paternity and the impact of latitude, climatic variability and habitat complexity on the extra-pair behavior, some problems exist during the studies and expectation in the future also referred.
