These are some very interesting vocalizations that are reportedly recorded from an area in Mississippi. According to the report they were recorded on December 15, 2002 and some believe these howls are clearly from a Bigfoot. It was recorded using a cassette recorder and microphone so the quality has its limitations and skeptics believe it may simply be Coyote howls but it seems rather odd and different from most coyote sounds. Whether or not it is the vocalizations of Bigfoot or not is sure to be debated for some time and more analysis is definitely needed.
Here is the actual audio and a little more information on the Mississippi Bigfoot recordings in this video. You can have a listen and decide for yourself whether or not you believe that these sounds are simply that of coyotes or perhaps it really is from a Mississippi Bigfoot.
