What drives the rut here
Montana's whitetail rut runs in the second half of November across the state's river-bottom timber and forest-edge habitat. The state has both whitetail and mule deer; whitetail dominate the river systems while mule deer hold the open prairie and mountain country. Montana FWP publishes deer harvest data and refines rut windows through field observations.
