The King quail (Excalfactoria chinensis), also known as the blue-breasted quail, Asian blue quail, button quail, Chinese painted quail, or Chung-Chi, is a species of Old World quail in the Phasianidae family. This species is the smallest "true quail" and is quite common in aviculture worldwide. In the wild they range from southeastern Asia to Oceania with 9 different subspecies. A failed attempt was made to introduce this species to New Zealand by the Otago Acclimatisation Society in the late 1890s.
