Sun Bear coming down to get us

One of the most spectacular wildlife sightings in my life. A Malayan Sun Bear in Khao Yai national park. The bear was building a nest in the tree. We watched him working for as far that was possible. Leafs of the trees obstructed our view. After a while he had a look at us and he came down. At first he seemed to be calm, but the last part he was definitely in a hurry. I decided to make a video, but because he was caming down faster than before I decided to run away. He roared when he touched the ground, but he didn't follow us.
Really, really exciting and amazing to see an animal like this in thick evergreen forest.
