In my area (north of Spokane 20 miles) this is the mildest winter since probably 1900 according to the weather forcasters. There is plenty of time for lots of weather to occur, it isn't all winter weather that hurts or helps wildlife. Wet springs devastate uplandbirds, forrest grouse and turkeys. Hot dry summers same to the berries which affect the bears and others etc.
Most seasonal things, start of rut. turkeys mating are controlled by day length, amount of sun, with a little temperature influence.
