LANGUAGE CONTEXT COMMENTS
"The Chorote, who are nomadic hunter-gatherers and fishermen, used to occupy much bigger parts of the Central and Southern Chaco, but they were probably pushed to the northwest by Guaicuruan groups that at their turn were displaced by the Spaniards."
In Paraguay "there were bands of uncontacted [Chorote] until well into the 1970s."
