This comes from the Squatch Team. I've been looking at their videos for a while for anything of interest and this is the first time I've posted anything on here from them, so here's a little background about who they are.
They're a husband and wife team, along with a few other researchers that mainly search in SE OK, Ark. and E. Texas. The husband/wife own property in SE OK and they do a lot of searching on it, and in other areas nearby. They have found a number of tracks on their property; one was 18".
They aren't exactly sophisticated but they look for tracks, set up for audio, leave "gifts" etc. and make videos of their activities to document what they find.
To their credit, they do get out a lot and search.
They have some other videos with things like tracks that I'll post in the future.
According to the husband, they set up an audio recorder and let it run all night and when he listened later on, heard this vocalization that he said happened about 2:00AM. It sounds like a howl but not your typical "Ohio" howl; it's rather unusual.
I thought I'd post it and let people hear it. The vocalization happens about the 1:34-1:35 mark. It's looped four times.
