It is an interesting subject. Most of my experience is the Pacific coast and South West Desert tribes.

I think the coastal natives invented the word pot luck. Whatever was available and easy went into the pot. Everything from lizards to rodents.

This image people have of the noble Red man riding his horse on a Buffalo hunt is for the most part is BS. Riding horses is recent 300-400 years.

One of my neighbors was a department head at UCLA. I collected for him on my hunts. I collected everything from Rattlesnakes to finding old Indian campsites. Documented my finds and reported. Collected wildlife.

The Pacific coast Indians lived hand to mouth, their campsites were pretty darned primitive and temporary. They followed the food supply seasonally, but would reuse the same camp sites for generations. The vast majority of the bones at a campsite were small game

A lot of mollusks, Rodents and other small game. Bones form larger animals were rare. One hypothesis is that humans were mostly scavengers and would steal kills form other predators.

One thing I found really interesting, many of the campsites could be spotted from the vegetation. Much (most) of the vegetation in a quarter mile radius from a generational campsite was edible. Kind of a micro flora of what was common in a broader area. Best guess is they would collect seeds form far and wide and their excrement closer to home would transplant edible species nearby. It was so common and persistent you can see it today if you look closely and recognize what you are seeing. You can walk around a many thousand years old campsite today and eat most of the nearby vegetation.

I think Bison was Tatanka in Lakota. Bison is a German word (maybe Latin) pronounced beeson. I think the old English word is Wesend
