Top Of My Potatoes And Sunflower Been Ate Off

As you can see in this video, something is eating the tops of my potatoes and sunflowers off.
White tail deer would be the only animal in my area that could reach a top of a sunflowers.
Deer as a rule do not eat potatoes tops.
And if it was a bear, he would have torn everything to pieces.
They had not touch anything for about three days now, I hope they do not come back.
