Saw this picture as I was flipping through my photos. This baby gorilla was following around it's mom and copying everything she did. The mom walked by and played with the plastic drum thing and then the baby promptly came in right as she left. The whole time the baby played with the drum she had her eyes on the mom watching to see what she would do next. It was a very interesting spectacle to watch.
Shortly after the photo the baby flipped over the drum and was trying to climb on top and stand, it was very cute and I wish I had made a video of it to share with you.
