Girls Eating A Turkey Leg

While large domesticated turkeys are generally unable to fly, smaller, lighter domesticated turkeys known as heritage turkeys and wild turkeys can fly. In domesticated turkeys the ability to fly depends directly on weight, while even heavy adult wild turkeys can fly well enough to avoid predators by taking off and flying up to 100 yards (91 m) and perching in tree branches. Turkey poults (chicks) cannot fly for the first two weeks after hatching.
Fossil record
Many turkeys have been described from fossils. The Meleagrididae are known from the Early Miocene (c. 23 mya) onwards, with the extinct genera Rhegminornis (Early Miocene of Bell, U.S.) and Proagriocharis (Kimball Late Miocene/Early Pliocene of Lime Creek, U.S.). The former is probably a basal turkey, the other a more contemporary bird not very similar to known turkeys; both were much smaller birds. A turkey fossil not assignable to genus but similar to Meleagris is known from the Late Miocene of Westmoreland County, Virginia. In the modern genus Meleagris, a considerable number of species have been described, as turkey fossils are robust, fairly often found, and turkeys show much variation among individuals. Many of these supposed fossilized species are now considered junior synonyms. One, the well-documented California Turkey Meleagris californica, became extinct recently enough to have been hunted by early human settlers and it is believed its demise was due to the combined pressures of climate change at the end of the last glacial period and hunting. The modern species and the California Turkey seem to have diverged approximately one million years ago.
