Favorite Nature Video

This video has been around for awhile, but it is my favorite nature video of all time, nature at its best. Does anyone know of others?
CompFused.com Videos - Lions vs. Hyena

Great video,i dont understand why people feel the need to take a great nature video & insert whatever form of music they enjoy, thinking somehow it adds to the enjoyment of watching the vid.

Great vid but 2 big thumbs down for the guy who added the music,the version that is narated is much better for me to watch.
