The mule deer rut is one of the most dynamic and captivating periods in the wildlife calendar. As late fall settles in, daylight shortens, and temperatures drop, bucks shift from predictable patterns to a restless, single-minded focus on finding and tending does.

With swollen necks and caution thrown to the wind, their movements push longer into daylight as hormones peak. #muledeer #muledeerrut #muledeerh
