Strong feet and easy walking, short wings, can't fly much higher and farther. The cry is monotonous and low. During the breeding period, nests are built anywhere in the grass on the hills, and hay and fallen leaves are spread in the depressions on the ground. Each nest lays 6 ~ 14 eggs, and generally, 2 nests are hatched 1 year. There are 19 pheasant subspecies in China.
