Smart is the word for this crow who is working hard to crack a nut. I took a video of him landing on the wires and dropping the nut. He actually got it to crack open. Towards the end you can hear a loud bong sound. That is his using a Jeep’s hood to achieve more impact on that nut. He got all shy on me then and stopped coming down. Here is a still photo of his hard work which I am sure he came and retrived once I left.
