The New International Encyclopædia…
“ Species of quail are found in different parts of Asia, although no other is so abundant as the common quail, and none migrates as it does. The rain quail (Coturnix Coromandelica) is numerous in India. The Chinese quail (Coturnix excalphatoria) , only about four inches long, is abundant in China, and is there kept for fighting, the males, being very pugnacious. It is also said to be used for another singular purpose—the warming of the hands of its owner. In America the word quail is used for all those small birds which have no feathers on the tarsus. ”
