In thinking about the happy outcome for Nibi the orphaned Beaver, Massachusetts newest wildlife ambassador, I was reminded of some footage I took of a Beaver over the summer (for the full story about Nibi, visit the Newhouse Wildlife Rescue Facebook page here).

The Beaver dove down to retrieve some kind of vegetative tuber or rhizome, a behavior I have seen countless times. He/she resurfaced, ate half, and then proceeded to use the half eaten rhizome to scrub his face. Okay that’s interesting but perhaps just a fluke. A few minutes later, the Beaver dove again and returned with a fresh rhizome, this time with his left side facing the camera. After munching away for a few moments, he then groomed the left side of his face with the rhizome in his left paw. Wow, so thorough to scrub both sides, and with a “tool!”

The video footage is longer than the usual post but he’s so cute at the end I had to include that, too. You can see his long orange tooth at about 1 minute 20 seconds in.

I wondered, are Beavers considered “tool users?” They build their lodges by cutting down and arranging trees, packing all with mud and that may or may not be called tool use, but to use vegetable matter to groom his face? That certainly seems as though it would qualify as tool use.
