My favorite time to hear turkeys is within the first hour of daylight. However, I've killed an overwhelming majority of my turkeys from 10:00-2:00, and then from 5:00 until dark. Too many hunters hammer them hard with all kinds of calls just before sunrise until about 8:00 and when the birds shut up, they think its over and head home for the day. I usually take a nap around 8:00 or so if the gobbling has stopped. Most of the time after the hens have left the toms, about an hour later the toms recharge and start looking again, except this time, they try to get to the hens before another gobbler and they can come in on a string in just a couple of minutes. My first bird of the year, on opening day, came at between 1:30-1:45. I bet he gobbled at least a couple of hundred times and strutted back and forth for close to an hour before he sneaked in for a peek. Fatal move! the second bird gobbled about 10:30 and was just barely audible from where I was. Two calling sequences later and he was within 40 yards. Soft clucks and purrs and he strutted right on in and I was tagged out at 10:45. Two mature toms in late morning to mid-day.
