What's the name of this bird?

This is a stone chicken, also called croak chicken, named after its cry. Pheasant is grayish brown, with dark brown striped feathers half the size of an apple on its chest, and slightly more striped feathers in males. The whole body is dark red except the mouth and claws, and the others are almost the same color. The gross weight of the big one is 2 kg and the small one is about 1 kg. Good at running, thieves run fast. Lying in a pile of stones, if you don't move, it's hard to find, a bit like "half wing"

When pheasants arrive in early autumn, they live in groups. There are more than 100 large groups and more than a dozen small groups. Most of them live in the mountains. In autumn, they go to the fields to eat crops, such as millet and potatoes. The destructive power should not be underestimated.
