Yes, that's a beaver. Late in the afternoon, my boss suddenly flew out of her office shouting, "Look outside right now!" LOL, so we all did. We're not terribly close to major water source (there's a small marshy creek in the ravine and another about half a mile away) and he looked awfully dry and ill. I am wondering if whatever happened to Mr. Bunny last week had a hand in injuring Mr. Beaver, too - coworker got pretty close, noticed what looked like a bite near it's rear end. :(
Various agencies were called, but it ambled away on its own. Shame, as I think the wildlife center might have helped it.
