"Squirrels here," Markovich says in the video. "Look at this guy."
Markovich marvels at the unusually close-up shot he is able to get of the apparently fearless squirrel.
"Oh my God, so close," Markovich says as he turns the camera.
A second squirrel staring at Markovich from atop a fence mere feet away then lunges at Markovich and appears to make contact with the camera, bringing an abrupt end to the video.
