Martin Clunes is noted for his documentaries with animals. In this short clip, he is watching wolves in the wild at Yellowstone National Park (USA). http://www.bing.com/videos/watch/video/wolves-in-the-wild/17ucvmpvb?cpkey=9b5fb7fb-43a7-45a0-8313-dfa86fd231fc%257c%257c%257c%257c
The second short video, also filmed in Yellowstone, shows the magical effects that have taken place since wolves were reintroduced in the park nearly 20 years ago.
