In Wisconsin, they have used radiotransmitters and found some turkeys were harvested over 15 miles from where they were originally captured.

One bird went 5.8 miles in a 30-hour period, but most stayed close to the capture site.

One other thing I read. They also studied mortaility of those turkeys and here is what they found:

55% killed by hunters
6% killed by coyotes
3% killed by poaching (they think - could not be verified)
2% killed by cars
