Only the Tom turkey makes the gobble sound.
In 1784, Ben Franklin wrote a letter to his daughter suggesting that the turkey was a more respectable bird than the eagle, and a true, original, native of America. It can be said that Ben Franklin preferred the turkey as the national bird of the United States. Interestingly, a tradition was established in which the current President of the United States pardons a turkey every year before Thanksgiving, thus allowing it to live the remainder of its life as a free bird without fear of landing on a famiy's dinner table.
In Mt. Gretna it is possible to see a wild turkey, but more probable to see a turkey vulture. This nonaggressive bird, with a keen sense of smell is not related to turkeys. These birds have been returning to Mt. Gretna for more than 25 years. Volunteers use different methods to scare the birds away, and although the numbers are down, every November they continue to flock to Mt. Gretna for the winter season.
