Bear has a different, local survival expert listed at the end of each episode. I've tried Googling them to see if they have their own websites, and most don't.

Bear's expert for the Everglades is a fairly well known author (don't recall his name right now) of local nature books, and is even featured on the board of tourism site.

The African expert has his own safari outfit, etc.

I find myself more interested in the credits than I am in the show itself!
