Baby deer keep their spots for 90 to 120 days. The spots fade as the fawn grows a thicker coat in preparation for winter weather. Therefore, deer born earlier in the season keep their spots longer.
Baby deer have spots to help camouflage them from predators. The spotted coat blends in with grass and foliage. Mother deer make bedding areas for their fawns in overgrown areas of the forest. The mother spends most of its time away from the fawn to avoid attracting predators. The mother returns to the bedding area a few times a day to feed her baby.
