The lack of scent means predators can't smell them. Fawns can walk when they are only a few hours old. When deer are walking, you can tell whether the track maker was a buck or a doe. The doe's wider hips will cause the hind tracks to fall to the outside of the line of travel. This is true only when they are walking.
Bucks have antlers which are shed once a year.
They don't branch from one main beam like those of the white-tailed deer do. There is a high population of deer here where I live on the northern coast of California. I see them feeding along the busy highway, in pastures with the cattle, in orchards, and everywhere on the property I caretake. I've seen them out feeding in the rain and even lying down to rest in the open when its raining. They seem oblivious to it.
