In WI they start the season on 10/15 and run it until either 02/28 or until the quota is filled. This year they hit their quota around 12/05 and closed the season at that time. Firearms deer season starts statewide the Saturday before Thanksgiving until the Sunday after, so I imagine the majority of wolves killed by hunters (as opposed to trappers, who kill the largest percentage) happen during those nine days.
I know a friend of mine has property in the western part of the state, and every season at least one person in our hunting group has a bow range encounter with a wolf. Although, I don’t think anyone’s had one that close yet this year. The neighbor to his north still sees them quite frequently along the edges of one of his farm fields, so they’re apparently still living in the area.
