White-tailed fawns have lots of small white spots on their fur. These serve as camouflage, since the dots make them harder to spot in high grass. When its mother is off looking for food, the white-tailed fawn hides in the tall grass. It stretches out flat on the ground, even laying its head and neck down flat.
Fun Fact: A white-tailed fawn can stand up 20 minutes after birth and after just five days is faster than a human being.
