Four recent archaeological studies suggest that macaws came to Chaco Canyon and Mimbres, New Mexico, from Mesoamerica and that the Mayan epic of the hero twins accompanied them to Mimbres. An episode from a narrative about the origins of a Diné (Navajo) ceremonial repertoire is analyzed here to suggest avenues for future archaeological research. The Diné narrative presumably has come from one or more of the many southwestern US and other groups that, over many centuries, have become integrated into the Diné clan system. The narrative is set around Chaco and features a birdlike personage from Waving Willow, a home of plants far south of Chaco, possibly Mimbres. The narrative agrees with archaeologists that Chacoans got ceremonial birds from the south. In addition, an analytical framework from cognitive psychologist David Rubin that can distinguish history in a narrative from the history of the narrative supports the possibility that with the birds came psychoactive plants and ceremonial procedures, including boys’ puberty ceremonies.
