During a 2016 archaeological salvage project in the municipality of San Francisco de Borja, Chihuahua, the mummified head of an adult military macaw (Ara militaris) was recorded from a rock shelter. Because of their aesthetic beauty and colorful plumage, macaws occupied an important place within the collective imagination of the pre-Hispanic communities. Macaws and macaw feathers also were important ritual and social symbols, often used in Pueblo ceremonial regalia. Radiocarbon analysis of the macaw has produced a Late Archaic calibrated date range of 150 BC – AD 20, making this the earliest macaw by several hundred years in northwestern Mexico or the southwestern United States. Stable carbon isotopes in this macaw were comparable to maize-fed domesticated turkeys from the Southwest suggesting some form of animal husbandry by this time. Our discussion includes comparison with the handful of other military macaws from pre-Hispanic contexts in northwestern Mexico and the southwestern United States.

在奇瓦瓦州San Francisco de Borja市的2016年考古抢救项目中，成年金刚鹦鹉（Ara militaris）的木乃伊头像）是从岩石掩体处记录下来的。由于其美丽的美感和色彩斑plum的羽毛，金刚鹦鹉在西班牙裔前社区的集体想象中占据了重要位置。金刚鹦鹉和金刚鹦鹉的羽毛也是重要的礼节和社交符号，通常在普韦布洛（Zes）仪式中使用。对金刚鹦鹉进行放射性碳分析后得出的晚期古埃及校准日期范围为公元前150年至公元20年，这使其成为墨西哥西北部或美国西南部几百年来最早的金刚鹦鹉。金刚鹦鹉中的稳定碳同位素与西南地区玉米喂养的家养火鸡相当，这表明此时有某种形式的畜牧业。我们的讨论包括与墨西哥西北部和美国西南部的西班牙裔之前的少数其他金刚鹦鹉进行比较。
