Unusual sounds continue to be recorded behind my home.

This sounds like laughter in the rain recorded at at around 6:00 p.m.

Recorded the 20th of December, 2011.

A year and a half ago I recorded a series of very pitched screams here in Central Illinois.

Please see:  Illinois Screamer – Pt. 1

In that post I posted Red Fox screams to illustrate the difference.

Woods behind my home.

This past week I have recorded what I think is similar screams. I also have a friend who lives about 1/2 mile from me. Just as it was getting dark he heard what he described as a very long loud high pitched scream. It was only about 75 yards from his back door and he did not investigate. He heard only one scream not a series. I emailed him my recording and he thinks it matches what I recorded.

I am not sure what this is, I don’t believe it is a Red Fox but possibly it could be a Bobcat or a Cougar.

This past summer there was a lot of work going on at the earthen dam near my home. Workers had been cutting down small trees and mowing a large area. The morning  of the 30th of July 1011 when I went outside I noticed this small tree (still with green leaves on it) had fallen onto the narrow roadway leading to the dam.

Although the tree looked old there was not a breeze last night, it just makes we wonder if something gave it a push and perhaps intentionally blocked all traffic on that small access road. Nothing dramatic but with the vocalizations I have heard this year and the rock throwing that both my wife and I witnessed I thought I best take a picture and write a short note.

I have been running two recorders at home each about 200 yards apart. I have attempting to get a idea of the direction that the sounds are coming from and hoping the outer recorder will have less of Belle’s barking. On the 16th of December, 2011 from my deck I recorded this far off  “yahoo” vocal which I think was perhaps 500 yards away.

My drop recorder recorded the same sounds. However, the dog barking (not Belle) is less pronounced. It gave me an idea of where the yells are coming from. Poor quality recordings because of the distance but it helps figure out the direction of the vocals.

For some time now I have been aware that there is something in the woods behind my house that once in awhile makes strange sounds.

The leaves are off the trees now and the woods in the daytime are fairly transparent. Deer are easily seen on the hill behind my house. I live on a small lake at the end of a spur.  I do have a few neighbors up the road from me but none next door.

At night everything changes dramatically.  It is extremely dark as I do not use any security lights or leave outside lights on.

The small valley behind my home.

I am doing audio recording 24/7 with a Telinga parabolic microphone.  The parabolic is mounted on a tripod and located on a covered patio which is covered by a roof and surrounded by three walls. Microphone cables go through a hole I created in my basement wall and then feed upstairs to my Sound Devices 722 recorder.

I live in a very quiet area. At night there is almost no vehicle traffic. The greatest problem I have getting good recordings is wind in the tops of the trees.

In the last month I recorded strange sound three different times.

I propose no explanation to the sources of the sounds only that I can verify that no one is wondering around in the woods behind my home at the late hours of the night. The rustling of leaves that is heard is my dog Belle running up closer to the house.

The 1st sound almost sounds like a low moan.

Recorded the 15th of November, 2011.

One could certainly wish to have better quality recordings but with the wind and distance it is not possible.

It has been a year since I recorded some unusual sounds at what I call the Troll Bridge. This bridge is located in rural Greene County, Illinois.

To familiarize yourself with the incident it would be best to read the three posts from last year.

Troll Under The Bridge, Pt. 1 

Troll Under The Bridge, Pt. 2

Thoughts on ‎”Troll Under The Bridge”

The discussion has centered around whether the sound that was recorded:

1. Is the sound bipedal or quadrapedal?

2. Is the sound that of a dog, a horse or unknown?

It must be remembered that I was unable to record either a dog or a man running across the bridge in that neither was heavy enough. I weigh 240 lbs and the recorder did not pick up any sounds at all as I ran back and forth the bridge. It is assumed that whatever was running across the bridge was very heavy. I was unable to find anyone living close to the bridge that raised horses. Therefore, I was unable to record a horse galloping across the bridge. However I found a couple of horse sound samples on the net.

Although I can not the answer the question as to the source of the recording  I can provide several other recordings for comparison, (Copyrighted horse sound clips courtesy of  Soundrangers.com)
