Wild and domestic turkeys: birds of a different feather
While
sitting down to enjoy turkey during the Thanksgiving holiday, remember that
although wild and domestic turkeys are genetically the same species, that’s
about where the similarity ends.
“The wild turkey in a sprint can outrun a galloping horse,” said Charles
Ruth, Deer and
Turkey Project supervisor for the S.C. Department of Natural Resources
(DNR). “Although it is one of the largest game birds, weighing up to 25
pounds, it can fly distances of more than a mile, sometimes at speeds of 55
miles per hour.”
Don’t ask a barnyard bird to try any of those feats! The domestic turkey
lost its ability to fly through selective breeding that created heavier,
broad-breasted birds, a feature much desired by chefs and commercial turkey
producers. The shorter legs of the domestic turkey also mean it can’t run as
well as its wild cousin.
In contrast to the heavier domestic bird, the wild turkey is slim, tall and
long-legged. Factor in its keen eyesight and native cunning, and the wild
turkey makes a difficult target for human and animal hunters alike.
Reintroduction of the wild turkey in South Carolina is one of the Palmetto
State’s most noteworthy conservation success stories. Limited at the turn of
the century to small pockets of birds in the Lowcountry’s Francis Marion
National Forest and along the Savannah River swamps, the wild turkey is now
so widespread throughout South Carolina that a month-long spring hunting
season is held in all of the state’s 46 counties (there is no fall season).
Wild turkey restoration was made possible through the efforts of the state
DNR, the National Wild Turkey Federation, the forest products industry and
South Carolina sportsmen and sportswomen.
The separation of the wild and domestic turkey began hundreds of years ago,
according to Ruth. Native Americans had accomplished the domestication of
turkeys before Europeans set foot on the continent. Turkey bones have been
found in Indian burial mounds in Tennessee, Kentucky and some other parts of
the South, and turkeys were being raised in Mexico and Central America for
more than 500 years before the Spanish arrived. Turkey relics have been
found in Arizona dating as far back as 25 A.D., and turkey-raising may well
be one of the oldest forms of organized meat production in the Northern
Hemisphere.
Spanish explorers took Mexican wild turkeys domesticated by the Aztecs home
to Europe in about 1519. The turkey then spread rapidly through Europe and
was introduced in England between 1524 and 1541, where they were highly
sought after for gourmet dinners.
After the domestic turkey spread across Europe in the 1500s, the colonists
who settled the New World brought these tasty birds with them across the
Atlantic to the land of their origin. Imagine the pilgrims’ surprise to find
the turkey already one of the most plentiful foods of the American Indians.
Domestic stock from Europe was eventually crossbred with the wild turkeys of
North America, leading to the six standard domestic varieties in the United
States: Bronze, Black, Narranganset, Bourbon Red, Slate and White Holland.
While the attributes of wild turkeys have been important in enhancing
domestic breeds, the flow of genetic material in the other direction is not
encouraged. State law prohibits the release of pen-raised turkeys due to the
possibility of introducing disease into the wild flocks and because of the
danger of contaminating the wild turkey gene pool.
But Ruth said because domestic turkeys lack the “wood smarts” of their
wild cousins, they generally fall prey to a host of hungry predators such as
bobcats, foxes or coyotes before getting a chance to breed with native
birds.
