Watch to the end if don't know Behavior of deer during the breeding season?

The mule deer is a species closely related to white-tailed and black-tailed deer. It is a successful species that is not endangered and enjoys a range in the mountains of western North America from Alaska to Mexico. Mule deer can have up to four babies at a time, a rarity for most deer species. Several species of carnivores prey on mule deer, but the biggest threat to them comes from humans through the loss and fragmentation of their habitat, disruption of their migratory patterns, and even the practice of feeding them in the winter which spreads disease and creates overpopulation.

Rut is a term used to describe the behavior of deer during the breeding season when males pursue females that are in estrous and ready to breed.
