When startled White-tails lift their tail and show the "flag" that gives them their name. The hairs also
are fanned out and the tail is moved back and forth to alert other deer to beware. Many times the only sight you have of a deer is the white tail bobbing through the woods as it departs the area.
The first fawn was soon joined by it's sibling and began running around obviously burning off excess energy before disappearing back into the woods. The mother never came out onto the lawn but rest assured she knew where they were every moment. Before the kids left the park I was able to give each a color print-out of the fawns they were able watch and enjoy.
