This is a question that often comes up and there are several theories about how a bigfoot could survive in harsh winter conditions.

Here are some of the most popular theories:

* Migration - Bigfoot travels to a warmer location.
* Hibernation - Bigfoot sleeps during the worse winter months.
* Specialized Behaviors - passed down from older bigfoot.
* Grows Thicker fur/hair during the winter.
* Builds Dens, Nest or stick structure

All of these could be possible but some are probably not likely at all.
First I do not think Bigfoot hibernate and if they do it must be for very short periods. I would guess the chances of hibernation is about 1-5 percent, if at all. Plus, we have many reported bigfoot sightings in the winter months, there wouldn't be any if they were hibernating. What they might do is stay put in some type of warmer location or shelter on the worse days of winter. I know from hunting experience that some animals just seem not to travel on really harsh winter days/nights. Now, that might be a moot point if the animal is really desperate for food.
