I don't doubt he placed animals in the area so he could stumble upon them, but I can understand that. When you're filming, you have a budget and a deadline. You can't afford to spend days, weeks trying to find an animal that doesn't want to be found. He still showed the animal in it's natural environment and educated us all about the animal and it's life and behavior. And that made us want to save that animal and it's environment, and think more about conservation.
