One thing I learned on the trip from a park ranger is that beaver are like rabbits in that they will re-ingest already digested food because the first pass of the wood fibers does not get that much of the nutrients. Today's Greek word of the day is Coprophagia. Nice!
Another interesting fact I learned:
When you see a lizard run and then stop, it is having to take a breath. Lizards cannot run and breathe at the same time. They have been around for millions of years and haven't got that figured out yet.
