Hi,
I just joined and not sure if this is the right forum section for my question but perhaps some viewers can help me.

For a few years now I've been looking for the name of a wildlife series ( either a six parter or a one off, I don't remember). It aired on either the BBC or perhaps Channel 4. I think it was between 2003 and 2007. It was about 30 mins long and was quite similar to the 'Predators' one. It featured a dramatic voice over and super slow mo with very sophisticated CG to illustrate things. It roamed all over the world and it's unique point was that it used CG to show things we can't see such as the radius of a Lions roar or satellite view showing a lions urine marked territory.
The clip I need showed ants on the hunt and the CG showed the line of ants with them branching out and the line rotating 360 degrees until they had foraged/hunted that whole circumference before moving on. The CG showed this very well.

I have searched for a long time for the name of this show but couldn't find it. Its hard to find because there were quite a few similar ones around that time such as 'Predators' and 'weird nature'. Hope someone can help me identify it.
