The main results are shown as follows. 　　 1.In winter, Blood Pheasant lived in flocks and four flocks were located in the main study area by tracing their tracks in the snow. The home range of wintering flock was stable. The home range enlarged before the flock broke up and overlapped with that of the neighbouring flock. During this period aggressive behaviour was observed. 　　2.The mating system of Blood Pheasant was monogamy and the pair bond lasted the entire breeding season. Only females incubated. During incubating period the home range of both males and females were far from the nest. The chicks were reared by both parents and together they formed a family unit. The immature males living in gr
