I took this one about four years ago in Badlands National Park in South Dakota. There’s a nice prairie dog town there in the northern part of the park and I sat and watched for quite a while as the little guys popped in and out of their burrows, gathering dried grass to line their maze of underground tunnels. It is believed that they do this for insulation purposes.
