I cannot agree that this is Bigfoot making noise. There is so much out there that makes noise. There is no way to know the noise does not belong to someone else. Click here to find out more. Keep reading after the video and perhaps you'll see what I mean.
Creatures that need to hide are not going to vocalize knowing there are humans in or around their territory. Most supposed Bigfoot vocalizations can easily be attributed to something else. The only time I believe one might vocalize is as a warning. I am not saying whether or not Bigfoot vocalize but it seems that an intelligent species bent on avoiding humans is not going to make a peep knowing that people are around.
