* Wolves: Wolves are apex predators that prey on deer, especially in areas where deer populations are high.
* Mountain Lions: Mountain lions are also apex predators that can take down deer, especially fawns and smaller adults.
* Bears: While bears are primarily omnivores, they will eat deer, especially during the fall when they are fattening up for hibernation.
* Coyotes: Coyotes are opportunistic predators and will prey on deer, especially fawns and sick or injured adults.
* Bobcats: Bobcats are smaller than mountain lions but are still capable of taking down deer, especially fawns.
It's important to note that these predators may not always be successful in hunting deer, and their presence can help regulate deer populations.
