"At this time they found domesticated turkeys among the Indians of that region, and within a few years the birds were introduced into Spain.[31]
"The part of the country occupied by the Spanish during the first few years of the conquest in which wild turkeys occur is the eastern slope of the Cordillera in Vera Cruz, and there is every reason to suppose that this must have been the original home of the birds domesticated by the natives of that region.
"Gould's description of the type of M. mexicana is not sufficiently detailed to determine the exact character of this bird, but fortunately the type was figured in Elliot's "Birds of North America."... In addition Gould's type apparently served for the description of the adult male M. gallopavo in the 'Catalogue of Birds Brit. Mus.' (xxii, p. 387), and an adult female is described in the same volume from Ciudad Ranch Durango.... Thus it will become necessary to treat M. gallopavo and M. mexicana as at least subspecifically distinct. Whatever may be the relationship of M. mexicana to M. gallopavo, the M. g. merriami is easily separable from M. g. mexicana of the Sierra Madre of western Mexico, from Chihuahua to Colima. Birds from northern Chihuahua are intermediate."
In this article Mr. Nelson names M. g. merriami and gives full descriptions of the adult male and female in winter plumage.
