Abstract: 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.
