A listener writes “I live in northeastern Illinois near the border of Wisconsin. My yard backs up to about 400 acres of Marsh and Farm land.
On July 4, 2013 my wife and I were up near midnight because a neighbor was lighting off fireworks, the evening was warm and we had our windows open. The firework show culminated in a grand finale which was whistling a spiraling kind of sounds all frantic and jumbled with the usual pops and bangs. When about 15 seconds went by I realized he was out of ammo, but just then we started hearing a very high pitched and loud series of whoooop whooooop whooooop. It was almost as if something were saying encore, encore,.. The whoops were humanish and my wife and I at first thought it was a excited child. Then the whooooops were moving around in the marsh, at first they seemed to come near the source of the fireworks, but they kept going for about 5 minutes and were definitely coming from in the marsh itself. I told my wife that it seemed strange for me to think it was human at that point. I dismissed it as a mystery.
Eight days later I lie awake in bed at 3:50am knowing I would soon be disturbed by my alarm clock. I get up early to get to the golf course that is about an hour away. Out of know where I hear the same whoop, I mean the same individual, you could tell, only this time it was more like a questioning type of whoop, like whooooooeeeep? Then an emphatic lower pitched whoooo whoooo came from within the tree line next to my neighbors house.
The first caller sounded like it was between our houses in my backyard! Which incidentally has a very nice apple tree that was in season. The same thing repeated but now the sounds were moving off into the marsh. I got out of bed after sitting stunned for a brief time, just then a patrol car from the sheriffs department was shining his spot light into my yard, exactly where I had heard the sounds coming from! He circled and stopped to shine it again into the same area.
I called the sheriffs department and they told me the officer was responding to a call of a man down? I have been an avid outdoors man my whole life, fishing many overnights along this very same river, I even fished several days in a row without stopping at times. I think I have heard just about every animal that is common or uncommon to the area, besides spending many weeks camping in the north in very remote areas. Nothing I have heard fit those humanish sounds, the only thing I could relate to that sound was primate or human, the only thing is the volume and clarity of the vocalists was not something humans could actually perform without distortion or almost yelling, as is noticeable on Finding Bigfoot when they try to make calls. They were so clear and loud, but also effortless.”
