This information has been copied from The Wild Turkey Zone Background
Originally existing in the millions, this turkey had depleted to extremely low numbers by 1920. Formal programs involving trapping and transplanting were initiated in the 1930's and today it exists over much of its ancestral range. Texas has the most Rio Grandes with a population estimated at over 600,000 birds. Physical Description The Rio Grande turkey, at full maturity, is approximately four feet tall with a slightly smaller body size than the Eastern wild turkey. It is pale and copper-colored having tail feathers and tail/rump coverts (short feathers located at the base of the tail) tipped with a yellowish buff. An alternating color pattern includes tan feathers with medium or dark brown buffed tips. The Rio Grande’s color is consistently lighter than the Eastern or Florida bird, but is darker than the same feathers in the Merriam or Gould subspecies. Feathers of the hen breast, sides and flanks are tipped with pale, pinkish buff. Range & Habitat The Rio Grande turkey was originally found in the southern Great Plains, western Texas and northeast Mexico. They have expanded their range and been introduced into Nevada, Oregon, Washington, Wyoming, Utah, South Dakota, and California. This race of turkeys generally occurs in areas having 16 to 32 inches of rainfall. The Rio inhabits brushy areas near streams and rivers or mesquite, pine and scrub oak forests. It may be found up to 6,000 feet elevation and generally favors country that is more open than the wooded habitat favored by its eastern cousins. The Rio Grande is considered gregarious and, nomadic in some areas, having distinct summer and winter ranges. They may form large flocks of several hundred birds during the winter period. It has been known to travel distances of 10 or more miles from traditional winter roost sites to its nesting areas. Since the areas they are found usually do not have many roosting trees, they will often use the same tree which makes finding them a lot easier. Their range in a lot of cases is determined by the location of their preferred roosting tree, the cottonwood.

The
Rio Grande wild turkey is native to the semi-arid areas of the southern Great
Plains states: Texas, Oklahoma, Kansas and Northeastern Mexico. It received its
common name from the Rio Grande River, which is the water supply bordering the
brushy scrub, arid country of some of its prime range in western Texas and
northeastern Mexico. This subspecies was first described by George B. Sennett in
1879 who said it was intermediate in appearance between the eastern and western
subspecies, hence its scientific name, Meleagris Gallapavo Intermedia.
