Honestly, the first video/audio reminds me of a very angry black bear I heard as a kid. When teh sound bounces around? It gets downright weird(er). Foxes in mating season can make you think the worst of the universe. But to me, having to listen through static and the rest? Impossible to be certain. I've heard tress "singing", in fact. (Wind in pines in a certain way) that at a distance you'd swear is a monster but ... nope. Just Mama Nature. I think we're so citified we've forgotten (collectively) what Naure sounds like. And I suspect some of these are manmade. Ever hear frozen metal swaying in a high wind? You get some *weird* noises.

I heard an animal being eaten alive once. It was night and the animal was screaming and then it had a gurgling type scream like its throat was full of blood and then silence. Being the animal lover that I am, I ran toward the sound but then I stopped because I realized there was nothing I could do and whatever animal was eating it, has to eat . Plus I didn't know what kind of animal it was that was eating it . Could have been a coyote and I didn't want to get attacked.
