We found this interesting discussion on YouTube regarding Bigfoot migration. YouTube user 72mhanna believes the theory that Bigfoots are migratory is "hogwash." Many experts in the Bigfoot community have speculated that Bigfoots tend to migrate to warmer climate to find food sources. He believes Bigfoots are nomadic hunters and thinks it's ridiculous to imagine a creature like Bigfoot walking south for the winter.
I personally feel the word NOMAD or NOMADIC hunters fits the BF better. A member of a group of people who have no fixed home and move according to the seasons from place to place in search of food, water, and grazing land.
A person with no fixed residence who roams about; a wanderer.
To me herds of water buffalo or geese have these mass migrations
When asked if Bigfoots hibernate, this was his response:
Hibernation is a possibility, but there are some great vids of BF in the Winter that seem very authentic. I personally feel they are most likely more active in the winter when food is more scarce. I also feel they know how to stay warm also, they might dig deep holes in the snow. Another theory might be the thickness of their skin or maybe they have an extra layer of fat. Maybe they have skin and a layer of fat similar to a buffalo. Buffalo get cold but they make it through.
