鸟类夜栖地选择研究进展

夜栖地可以为鸟类提供安全、舒适、温暖的夜间栖息场所。昼行性鸟类夜间视觉能力较差,对夜栖环境中潜在的威胁感知程度较低,导致其夜栖时常常处于被动和危险的环境中。鸟类通过选择适宜的夜栖地,进而达到充分利用夜栖地空间资源的目的。本文从鸟类夜栖地选择的行为适应性以及保温性、食物因子和安全性(隐蔽性)等3个影响因素,对国内外鸟类夜栖地选择相关研究进行综述,为今后该领域的研究提供更多思路。

Roost habitat selection by birds: A review

Roost habitat can provide safe, warm, and comfortable site for birds rest at night. Because of the poor night vision capability, daytime-activity birds are difficult to perceive the potential threat of roosting environment, which make their roosting in a dangerous ambience. By choosing appropriate roosting sites, birds can take full advantage of roosting space resources. From the aspects of behavior adaptability in roost habitat selection and related affecting factors (temperature, food, and safety), this paper reviewed the researches on the roost habitat selection by birds, aimed to provide some useful ideas for the future study.
