A farmer in the US has found an artistic way of using his drone on his farm - using it to film his cow art.

Kansas farmer Derek Klingenberg used his drone to capture him forming his cows in the shape of a smiling face. Klingenberg used feed to draw the outline of the face and his feed truck to guide his cows into place, while filming the whole process from above using his drone.

This isn't the first time Klingenberg has starred in a viral video with his cows. He also captured himself serenading his herd with a trombone cover of Lorde's "Royals" while come running to watch him.

The serenading clip has been viewed over eight million times on Youtube. His herd also feature in many of Klingenberg's other videos on his Youtube channel.
