I posted this video yesterday but I’m not sure you made time to watch it. Do. It is the finest beaver video I have ever seen. And it fills my mind with questions.
Here’s just a few. Did the photographer place those stones the day before to see what the beaver would do with them? Does the beaver know the surface of his pond floor so well he realizes something changed? How well does he remember? Does he “see” the rocks or “feel” them? The beaver comes back to get them all, How does the beaver know what all means? Does he count? Does he just know vague terms like all and more and some?
Did the photographer use a light underwater? It looks like there is a reflection above the beaver. Are there reflections underwater?
