An impressive piece of artwork shaped like an owl's head has been filmed via drone in a snowy Wiltshire field.

Comprised of perfectly smooth lines, the geometrically perfect image was discovered by 59-year-old walker Chris Barrow on Roundway Hill, Devizes, Wiltshire earlier this month.What makes it particularly intriguing is the extreme precision of its creator, especially given that it has been so carefully measured out and there is only a single set of footprints leading away from it.Barrow was able to use a drone to captured aerial footage of the image."I couldn't believe it when I saw it," he said. "I just came across it by chance. It looks like completely virgin snow. It was fantastic to see. I don't know how they have done it."
