I have whitetails around my place from late April to Thanksgiving or shortly after. It seems the muledeer run them out; one day I'll see whitetails, the next mulies. Mid to late April, the mulies leave, a week to 10 days later I start seeing whitetails again. I have only once seen both species here at the same time in the 20 years I've lived here; it was mid December, and they were in separate groups. All the whitetails that day were bucks.
I've never seen anything around here that appeared to be a crossbreed, but did a few times in the Yaak valley over a period of 15 years. They were always with a group of whitetails.
