That is so cool! I actually got to watch a mama deer with two fawns teaching them how to respond to her signal to startle. They were just tiny and they were in the backyard right outside my bedroom window and she would stamp her foot on the ground and jump sideways and they would just stand there and look at her, like where you going mom? And then she would come back and do it again and stamp her foot and jump sideways. I think she did it 5 times before they finally figured out that they were supposed to react. Until seeing it, it was not something that I realized that the young ones needed to be taught. But it was obvious that she was teaching them.
