The king quail (Coturnix chinensis), also known as the button quail, Chinese painted quail, Chung-Chi, Asian blue quail or blue-breasted quail, is in the same family as the pheasants Phasianidae of the order Galliformes, gallinaceous birds. These birds all have a distinctly larger breast-bone than other birds with more muscle surrounding the area. This is why they are hunted for their meat.
