By way of example, when I lived in NJ, I heard several very strange cries out in the woods, but never actually saw anything. The incident that stands out the most was a series of cries that changed location each time, and several times seemed to be either in the air or a tree, in motion, or both. My friend was with me, and after some deliberation, we concluded that it must be an owl. But was it? The screams match accounts of mountain lion howls (”like a woman being murdered” I believe is the most succinct description), and could definitely be described as bloodcurdling, an adjective often used to describe the sounds of the Jersey Devil.

I suppose if you had an area you suspected was inhabited by a vocal cryptid, these accounts might be useful to you in establishing likely stalking grounds and possibly modes of behaviour (If you collected enough of them), but by themselves they must remain simply anonymously anomalous.

How could that be?
