The Saipan Jungle Fowl is a breed of domestic chicken. Not a true jungle fowl, it was found on the island of Saipan. It is thought to have been brought into The United States of America by returning American servicemen at the end of World War II including B. W. Saylor, who wrote "The Saipan Jungle Fowl" in 1977. Although the birds encountered at that time were both domesticated and wild on Saipan, it is thought that the wild ones were feral and decended from those brought in by the original human inhabitants. An alternative theory is that they were brought in by the Japanese as occurred in other locations such as Taiwan during the Japanese colonial occupation.
The "Saipan" bird is tall and upright, resembling the Malay, the Shamo, the Asil, or other oriental gamefowl, that are Asian in origin. The Saipan is either pea combed or flat combed and is absent of wattles, having a simple dewlap instead. The rooster is most often Black Breasted Red and the hen Wheaten in color, but there are variations such as white and other color combinations. It is known to have been used in cockfighting and is often bred into strains of gamefowl.
