Deer are a species in the Animal Crossing series that were first introduced in Animal Crossing: New Leaf. Male deer have a pair of antlers atop their heads, while female deer do not, making them the second villager species with a significant trait difference between male and female (the first being Kangaroos). Some deer villagers—like Zell, Lopez, Bruce, and Beau—resemble antelope, a species of mammal which have horns instead of antlers and are more closely related to cows than they are to deer.
