Mink are probably 99% nocturnal,plus have a large home range -they are never "thick". I can see otters, beaver and bald eagles pretty much daily. Gray fox used to be very common and easy to call. I had a couple friends that called and killed 14 in one night probably 35 years ago. I haven't seen one or had one on camera for over 25 years,yet there is a hunting and trapping season 5 months long with no bag limit. Anyone here seen a gray lately?What are they based on? I've never laid eyes on a wild mink in Indiana but I know we have no shortage of them and they are fair game for trapping. Otters were trapped out of Indiana, were reintroduced and now they can be trapped again due to the population reaching sustainable levels.
