Quick Answer
Identify signs of mule deer rut activity by looking for buck scat with a high concentration of ash and sand, which indicates a buck's digestive system is working overtime to process the increased protein intake during mating season.
Pre-Rut Signs
Before the rut peaks, mule deer bucks will start to exhibit increased activity, especially during twilight hours. Look for buck tracks with large, cloven hooves and a strong scent. A buck’s antlers will also start to develop, and some may already have a slight reddish tint on their faces, indicating the start of the rut.
Rut Activity
During the peak of the rut, mule deer bucks will be actively searching for does. Listen for bugling sounds, which are a common sign of rut activity, particularly in areas with a high concentration of mature bucks. Bucks will also start to fight more frequently, which can be seen as they spar with each other over mating rights. Be aware of the time of day, as rut activity typically peaks during the late morning and early afternoon.
Post-Rut Signs
After the rut, mule deer does will typically enter a period of gestation, and their behavior will be more sedentary. Look for does with a belly that appears swollen, indicating they are pregnant. Bucks will also start to lose their summer coats, and their antlers will begin to shed. Be cautious when approaching these areas, as bucks may still be defensive of their territory and may charge if they feel threatened.
