A beautiful video has emerged from Yellowstone National Park in the United States of a grey fox diving under the snow to hunt.

In the video, which was captured last week by a holiday maker, the fox leaps into the air and then dives head first under the snow.

The fox surfaces with a small rodent in its mouth, most likely a vole or a shrew.

The grey fox is the only canid (dog-like mammal) whose natural range spans both North and South America and it is the only American canid that can climb trees.
