I find some of my summer bucks leave in early fall, new bucks show up for rut, then they leave and around new year another different bunch of bucks show up. Some stay all winter through summer and some leave at spring green up. I've never been able to peg an expectation for most bucks. They do something different every season. But sometimes I get a homebody who either sets up camp and stays, or consistently repeats major movements so I can predictably hunt them. Otherwise there's no rhyme or reason that I know for for where they go or which bucks will be around any given time.
