I heard one about 30 yrs. ago. The most eerie scream I have ever heard. Sitting around a fire one night about 9:30. Made the hair on my neck stand up. Couple nights later I talked to a neighbor and he lost 2 dogs that night. Both torn up.

We had a few sika that would make a screaming sound. Guest would come back to camp with eyes wide open thinking they had heard a Bigfoot. It seems any unidentifiable sound is a Bigfoot.

A cougar, which sounds like a woman or child screaming.
One sound I still don't know what it was. It was about 4pm. 2 of us sitting in a crappy blind that had no door or roof. It was very quiet then this sound started. It sounded like someone positioning their lips like sucking thru a straw. It started quiet & slow but gradually (over about 2-3 seconds) got faster & louder. Something similar to a jet breaking the sound barrier by the end of it. It became insanely loud, almost so loud it hurt our ears. Crazy sound.

Sounds like it could have been baby buzzards. The only time I heard them I compared the noise to what a dragon would sound like. I can see how someone could compare it to a jet engine Amazing how loud it was

A mountain lion screaming like a woman right at dark when I was about 13 ...I made tracks straight back to the house.

The hair on my neck just stood up typing this 40+ years later....

Neighbors of ours booked us a tour of Gorman cave at TPWD Colorado State Park for my family and themselves. My neighbor, in his younger days, explored the cave many times. Now you can only take a tour with a TPWD staff. The cave goes a good distance back with small side tunnels breaking off. We track through some low spaces and a small amount of water. We get to the back area and my neighbor reluctantly shows us and the park ranger the graffiti he put there 40+ years ago when it was privately owned, he is now a nature lover and would never do such a thing again. Then the park ranger had us do the normal thing most cave tours do, turn off all the flashlights just to see how dark it is. It was then we hear the loudest growl I have ever heard in my life. All my hair including my pubic hair stood straight up! Try to keep your city wife and children calm in this situation. The flashlights immediately came back on. I locked eyes with the park ranger and we downplayed what we just heard to everyone in the tour group and we calmly and swiftly made our way out of the cave. The park closed the cave after our exit and a group of park rangers went back the next day only finding mountain lion tracks everywhere.

Sir, you have had one horrible run with the kitties in your lifetime!

Have any of you guys heard anything or seen anything that you could not explain as a cat or a elk?

About 2 years ago, Me and brother were out night hunting for pigs, we had corn out in a 40 yard by 40 yard clearing , and we were in a tree stand roughly 25 feet up, about 11:30 PM.
About 20 yards behind us we hear footsteps, not like a quadpedal or hooved animal. But like you would hear a human walking , so we readied our weapons,
Looking at my watch it's now 11:38 and we are still hearing movement behind us just lingering in one spot.... But moving closer, I look at my watch again, 11:41PM, foot steps come right underneath us, but off to the right about 5 feet. We are sitting in the stand like statues with our hearts going 300MPH, then comes the stinch. It's not pig stinch, it's like a skunk, shoved up a rotting carcass, the steps proceed around behind the stand and stop again about 15 feet behind us, and we hear breathing, it's not one of us, it's like breathing when your sick, and have gunk in your lungs like raspy breathing.
It's almost midnight now, so 30 minutes of this being circling us, it finally makes its way to the north, which is where Camp creek runs through and provides a good waterway as it is not very deep.
We wasted no time gathering our gear and bolting to his Truck 100 yards away. I bet not even the fastest NFL receiver could have out ran us that night.

what was it? I don't know. At the time I always thought of Bigfoot as a fake figment of imaginations.
After that, I wasn't so cold hearted.

It's also strange to me as we have always found nice healthy tree branches snapped for no apparent reason along trails or near creeks, we also run cows, and there have often been occasions when we go feed, they will look at the tree line and throw their head up like they see something.
And sometimes we'll get over there and they are all spooked and jumpy.
I'm not saying there is a Bigfoot , but I can certainly say I do not doubt it.

I do not go into the woods there now without a rifle, or I always carry Buckshot or Slugs with me if I'm dove hunting.
I can say I was truly scared.

Y’all didn’t have any lights? How were you going to see pigs?

I once saw a staircase in the middle of nowhere, in nowhere Texas, on the Brazos. Crazy [censored].

Nothing will wake you up faster then walking to your blind in the dark and suddenly stir up a flock of quail. Never got used to that.
