What are some good channels about animals?

I could suggest some from the Animal Planet network or Animal Planet's website.  But I don’t think the right keywords to use to search for it would be “animals” and “channels”, but rather, “animals tv” and “animal channels” and “animal channel”.  The first result I found on Google for “animal channels” was an Animal Planet website that contained the video listing and navigation for the full channel network.
