Predicting Peak Rut Activity & Days to Hunt Deer October 14, 2012 Minnesota, Minneapolis Star Tribune, T.R. Michels
... My studies in Minnesota show that roughly 10-20 percent of the does come into estrus during the early breeding phase (approximately October 15 - September 7 in the upper Midwest), 50-60 percent during the primary breeding phase (approximately September 8 - 28 in the upper Midwest), and 20-30 percent during the late breeding phase (approximately December 1-21 in the upper Midwest)... The breeding phase for deer in each area is predominantly triggered by the number of hours of sunlight each day (photoperiod).
