Here are some Barred owl calls, that usually occur at dusk, and are used to locate other owls. These sounds are quite loud, about the same as a dog bark, and can be heard for a mile. To him, this was all the proof required that Bigfoot has origins further north, and was intelligent enough to keep this sound in their language. Sometimes, these Barred owl calls can repeat, at about 10 second intervals, for dozens of times. It's common for two owls to communicate back and forth between hills by using the above calls, these calls, or calls like this.
Barred owls are quite capable of a variety of screams, either singularly or in groupings.
Here are two samples. They have yet to provide any proof of why this, documented Barred owl scream, is from a Bigfoot. We have also heard other recordings made in the area, all were also, although less fantastic vocalizations of, Barred owls and their screams. This hoax has been around since 1994, fooling and misleading many. To Sum it Up T he above are examples of how common sounds, in the minds of imaginative researchers, can become evidence of a creature that may or may not exist.
