Yup. The rut range expansion/shift usually begins around Halloween in my area. I will pick up the first pictures of most of the rut range shifters between the last few days of October and November 15.

These range shifters just passin thru, or do they go somewhere new and stick around?

These are bucks that normally don't utilize the monitored property, but due to either range expansion or acual range shifts, start using the property just before the rut peaks. These bucks usually continue to use the property for 4-6 weeks before disappearing back to where they came from. Some rut range shifters/expanders show up on the monitored property year after year, but only during the rut.
