Thanks-
The definition given for “nomad” by the Ameerican Heritage Dictionary is: “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.” These Amerindian tribes did in fact have “no fixed home” and did “move according to the seasons from place to place in search of food, water, and” land for gathering herbs.
They are pretty much a textbook example of a nomadic or semi-nomadic lifestyle, missing only the grazing livestock and reoccupation of townsites for longer periods of time than plains nomads in the Old World and New World.
