I estimate that a 800 lbs mammal is going to need roughly 8800 calories per day to maintain its body weight.
A 400 lbs silverback gorilla eats roughly 40 lbs of vegetation (plus a small percentage of insect protein) per day.
What would the caloric intake of say a family of 5 Sasquatch be per day? Approaching 50k right? Or in vegetation consumed terms it's right about (80 lbs or double gorilla daily intake X 5) 400 lbs per day per family troupe.
Thats a lot of veggies.
What if the troupe killed a whitetail deer?
4 oz of meat equals 170 calories, so 1 lbs equals 680 calories. So a 200 lbs deer represents 136000 calories, not counting the loss of bone and or antler weight. 8800 cal X 5 equals 44000 calories. So a average sized deer represents roughly 3 days worth of meals for a family of five.
Thats roughly 121 deer per year or 24333 lbs of annual meat consumed.
Check my numbers guys.....
In the Virunga range trackers follow mountain gorillas around by the swath of vegetational destruction they leave behind. These gorillas are like lawn mowers constantly moving along the mountain side. Family troupes up to 20 all feeding together. They also recieve some protein eating insects.
Of course gorillas can forage all year long in Africa. North America is a different story is most regions minus some gulf states and west coast. So if your caching food stores all summer for the winter months? A conservative estimate minus spoilage and increased caloric winter need, would be doubling the daily 400 lbs of vegetation collected to 800 lbs per family.
Gorillas spend 60 % of their day simply chewing their food. That doesn't leave a lot of time to sleep, mate, play, teach babes and collect food for winter months for a Bigfoot.
Meat must play a heavy role in winter time. But the snow is crunchy, the background is white, the leaves have fallen. Not good ambushing. So they must either store plant material away or hibernate. But Apes don't hibernate that we are aware of.
Anyhow just some crunching data in my mind tonight.
