"Revealing the Ancient Breeding History of Scarlet Macaws"
Scientists have discovered evidence of scarlet macaw breeding in what is now New Mexico during the 1100s, predating known breeding sites in Northwestern Mexico. Analysis of eggshell fragments found at the Old Town archaeological site revealed evidence of fetal development, indicating macaw breeding was occurring at the site. This finding provides insight into the practice of breeding and keeping macaws in the Americas and suggests that scarlet macaws were transported and kept as far north as the desert Southwest in the United States as early as the 600s.
