Jungle fowl (Gallus bankiva). (Courtesy of New York ZoologicalGardens.) body feathers almost identical with those of the modern brownLeghorn female. In voice both male and female resemblethe common barnyard fowl. The crow of the wild male,however, is not so prolonged as in the case of his domesti-cated brother. In action they are quite similar to themodern Leghorn. These birds cross readily with domestic breeds, producingfertile offspring and are themselves easily domesticated. While these considerations seem to point toward the BREEDS OF CHICKENS 51 bankiva as one ancestor of the hen as we know her, theydo not necessarily prove that it was the only ancestor ot themodern fowl nor that it was necessarily a progenitor ot allbreeds of chickens.

Davenport.) 52 , POULTRY PRODUCTION As Brown1 (whom I have largely followed) points out,there are excellent reasons for believing that such heavy,loose-feathered breeds as the Cochins and Brahmas camefrom an entirely different ancestry with which the Aseelor Malay fowl, domesticated over three thousand years ago,is the connecting link. In these breeds the long axis of theopening of the skull through which the spinal cord passes(occipital foramen) is perpendicular, while, in both theLeghorn and bankiva it is horizontal. This is mentionedas representative of several structural differences whichcould not have been selected for. It can be noted onlyby removing the head from the neck. Besides structural differences, there are also differencesin habit which seem to indicate an ancestor far removedfrom the close-feathered, early-maturing, high-flying junglefowl. The question of just what was the forerunner of our heavybreeds is an open one. While v
