Are the BF's farming or what?

So a 400-500lb biped must need to consume 3k - 4k calories a day - that is a hella lot of twigs and berries.

Hard to believe that a big primate could survive up here as a hunter/gatherer - scratch that, doubt old Biggie has progressed to the point of manufacturing firearms - so basically not a hunter, mostly a scavenger. (and a pretty damn good swimmer if he's porposing around catching salmon in the river)

Seems like you could find one if you just staked out a big old blackberry patch for long enough.
