But you do occasionally show cutting-edge research, and you have identified some new species...

That's true. For this latest series about mammals, we put an endoscope into a beaver's lodge in the middle of winter to see what goes on, because nobody had looked at that before. Through the endoscope we saw things that looked like small beavers that turned out to be muskrats. Nobody as far as I know has published the fact that muskrat are commensals with beavers in winter, and from some of the shots it even looks as though the muskrats are bringing in bedding for the beavers. That is not a high-grade discovery but it is nonetheless new. I can tell you it is very touching to see it.
