Owls are beautiful. I have many owl neighbors in the woods around my property. One night I was standing outside my back door. I heard the most insane call - like a howler monkey on acid. I knew we had no mammals here that could make this kind of outburst. I searched on line sites for bird calls . The closest I could find was a screech owl. This call was more than likely made by a large bird because of sheer volume and resonance. Screech owls are not very big but this is my closest guess.

God thinks it's fun to confuse primates. Larsen's God!
