Abstract: Urban green land is a kind of habitat shelter which relates to bird safety, and birds can show obvious preference in habitat selection. With the acceleration of urbanization, how to adapt to the disturbance of urban environment and reproduce successfully is a vital problem faced by urban birds, and the nest site selection of birds in breeding period reflects bird life history strategies and urban adaptability of urban birds. In order to explore the adaptability of urban birds, nest and nest-site characteristics, we collected 5 parameters of white-rumped munia’s (Lonchura striata) nest and also 19 ecological factors of 39 nests from March to May, 2017 in Yizhou City of Guangxi Province. The results showed as follows: the nest parameters were characterized in that—the outer diameter was(123.95±15.25)mm， while the inner diameter was(102.01±9.51)mm, the nest deep was(84.8±9.07)mm and the nest height was (115.66±9.37)mm, and the nest height to the ground was (3.64±1.17)m. The principal components analysis showed that there were 6 most important factors which affect the nest characteristics of white-rumped munia in spring and the accumulative ratio of contribution achieved was 83.607%. Safety factor（i.e. height of tree, tree coverage and canopy), played the most important role in habitat selection and the second to the forth factors were food factor(i.e. distance to human settlement and road and forest edge), interference factor(i.e. shrub coverage and height, herb coverage), and water factor(i.e. distance to water), and the last factor was geography factor(i.e. altitude and slope). In order to avoid the influence of human disturbance, white-rumped munia tend to locate its nest in the place with high hidden that next to the top of tree, and it shows the adaptability to urban habitats during breeding period.
