Born2hunt welcome to turkey huntin!!S&R gives great advice and I'm sure your situation falls under one of his conclusions!I know in my own home area we definately have a spring and winter range the birds show upin!I would also suggest that the gobbler you harvested had made your turkey woods behind your house his own home area and thus never left!Alot of times 2 year old gobblers or even satelite gobblers never really have home turf and can wander out of an area in a short amount of time!Dominant gobblers will drive them out and if they dont they rarely gobble and generally avoid the hens being afraid big daddy will show up and givem a butt whoopin!!On many occasion 2 year old gobblers will join together as a result of this and wander in and out of different areas they frequented earlier in the year!Another possibility is the lack of hens!I have seen gobblers leave an area once the major majority of the hens are bred!Gobblers will hen hunt and travel to find them if they have too....There may be no single one answer but a little piece of many of these suggestions could be a possibilty,whatever the case it happens all over the country thats why it so important to keep staying at it even if you encounter quiet woods on occasion!I heard more gobbling activity in the evenings on some days this year than at dawn,and its beginning to be quite common!Predation could be the answer including hunters or even the possibilty that wiser gobblers have learned to pattern us!!!
