The Rio Grande wild turkey (Meleagris gallopavo intermedia) has the largest population and the widest range of the three turkey subspecies (Rio Grande, Merriam�s, and Eastern wild turkeys) found in Texas. Unregulated hunting in the 1800s greatly reduced the Rio Grande wild turkey (RGWT) population in Texas to about 100,000 birds by 1920. Since then, their numbers have recovered thanks to better habitat management, restocking programs by Texas Parks and Wildlife Department (TPWD), and partnerships with landowners and conservation groups. However, there has been a steady decline in their populations in certain regions since the 1970s, which prompted TPWD to partner with universities to study the biology and habitat requirements of the turkeys in different parts of the states. The RGWT do not occupy the Trans Pecos and High Plains ecoregions of Texas. Typically, they inhabit areas that receive enough rainfall to sustain their food sources. The Edwards Plateau is their historic geographic center and has the highest number of RGWT today. Male turkeys are referred to as �toms�; males of breeding age are �gobblers�; females are �hens�; juveniles are �poults.� The bodies of wild turkeys are covered with 5,000 to 6,000 feathers. These feathers provide insulation, lift during flight, and touch sensation and ornamentation. A wild turkey undergoes five molts (feather replacement) during its lifetime: natal, juvenile, first basic, alternate (first winter), and basic (adult plumage). The body feathers of toms are vibrantly colored: iridescent copper, bronze, red, green, and gold. While hens have these same colors, they are significantly dulled and muted which causes the female to appear brown. Gobblers have a beard, which is a cluster of long follicles in the center of their chest that can be an inch to 10 inches long. Unlike the rest of the body feathers which undergo 5 molts throughout an RGWT�s lifetime, the beard does not molt. It becomes visible when the turkey is 6-7 months of age, and it continues to grow throughout their lifetime. Hens may occasionally have beards, although this uncommon event produces much shorter beards than toms. Both toms and hens have sparsely feathered heads with bare legs and feet that are pink to red in color. Toms grow a spur on the lower third of their leg that starts off small and rounded, but which becomes pointed and about 2 inches long with time. Hens also have a spur, although their spurs stay small and blunted. Gobblers weigh 17-21 pounds and attain a height of 40 inches. Hens weigh 8-11 pounds and are 30 inches tall.
