Abstract
To study the differences on nest-site selection of Grus japonensis between semi-captive and wild individuals in Zhalong Nature Reserve,a comparative research was conducted by the factor measurement method in Zhalong Nature Reserve from March to May,2009. Results of Independent-Samples t-test indicated that in the nest-site selection of G. japonensis of Semi-captive and Wild Individuals,difference was found in the heights of vegetation,density of vegetation,the area of reed surrounding nests and the distance of nests from areas of human activities. The results showed that the Wild Individuals of G. japonensis have strong selection to the nest-site. They preferred to feed in the place with less human activity,higher vegetation,bigger the density of vegetation and the area of reed surrounding nests. The Semi-captive Individuals of G. japonensis have weak selection to the nest-site.
