Macaws and parrots were important birds in prehistoric Mimbres-area communities by A.D. 1000. Scarlet macaws (Ara macao) apparently were imported into the area from the tropical lowlands in Mexico, but one other species each of macaw (Ara militaris) and parrot (Rhynchopsitta pachyrhyncha) probably could have been obtained from much closer natural ranges. Macaws in particular evidently were of special, perhaps ceremonial, importance as indicated by consistent age at death, probably reflecting sacrifice in the spring, and by deliberate intramural burial, often in special rooms in the community. The sacrificing of macaws and the season in which it occurred were consistent in Mimbres and contemporaneous sites and began a pattern that continued in the Southwest perhaps until historic times.
