This is the funny head-bobbing great-horned owl spotted screeching in Ardmore, Oklahoma at Lake Murray state park by this filmer on November 7.

"I think he or she was protecting a nest, the screech, after doing some research, we found out to be a defensive screech. A lot of people on my Facebook commented how neat it was! He or she never moved and remained perched and focused on us until we walk on by," the filmer said.

Encountered a great horned owl sitting on a limb and screeching at us for being near by. He never moved and remained perched and focused on us until we walk on by. In researching a little, we found it was a defensive screech. The owl might have have prey or babies near by and was trying to distract or scare us away.
