On a sunny spring day some 15 years ago, I was helping my friend and fellow biologist, Tim Beaulieu, with vernal pool surveys in the Dracut woods. Suddenly, what appeared to be a light sprinkle of rain began falling about 10 feet from us.

“That’s weird, I don’t see any clouds,” I said. “Where is that rain coming from?” Upon closer observation, we realized it wasn’t rain at all, but rather a porcupine urinating from a tree branch about 30 feet above. I don’t see porcupines often, so it was exciting, in spite of almost being peed on.
