The ethnobiology of the Papago Indians. Ethnological Studies in the American Southwest II.

"The Tohono O’odham ... are a Native American people of the Sonoran Desert, residing primarily in the U.S. state of Arizona and the Mexican state of Sonora. Tohono O’odham means "Desert People." The federally recognized tribe is known as the Tohono O'odham Nation.

"The Tohono O’odham have rejected the former name Papago, used by Europeans after being adopted by Spanish conquistadores from hearing other Piman bands call them this. The Pima were competitors and referred to the people as Ba꞉bawĭkoʼa meaning "eating tepary beans." That word was pronounced papago by the Spanish and adopted by later English speakers" (Wikipedia article on Tohono O'odham, accessed 03-2017).
