When the young are born, they have spots and lack scent. This enables them to hide from predators. They spend a lot of time curled up on the forest floor, sleeping. The spots provide camouflage. 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.
