Japanese Quail

The Japanese quail, also known as the coturnix quail, is a species of Old World quail found in East Asia. First considered a subspecies of the common quail, it is now considered as a separate species. The Japanese quail has played an active role in the lives of humanity since the 12th century, and continues to play major roles in industry and scientific research. Where it is found, the species is abundant across most of its range. Currently, there are a few true breeding mutations of the Japanese quail. The varieties currently found in the United States include Pharaoh, Italian, Manchurian, Tibetan, Rosetta, along with the following mutations: sex-linked brown, fee, roux, silver, andalusian, blue/blau, white winged pied, progressive pied, albino, calico, sparkly, as well as non-color mutations such as celadon, which lay blue-tinted eggs.
