I Heard Something Strange While Car Camping in Tennessee 

Hi!!!!! In this video I camp in a very special place--the first place I solo camped at the beginning of my trip. When I was about to eat my dinner, I heard a very STRANGE sound in the woods. I have no idea what it is or what it could be as I've never heard anything like it. Can anyone tell me what it is? Sorry if I'm freaking out over a bunny or a bird. LOL.
Strange sound starts at 8:15
