Two Foreign Macaw Species; Final rule.

We, the U.S. Fish and Wildlife Service (Service), are listing the military macaw (Ara militaris) and the great green macaw (Ara ambiguus) as endangered under the Endangered Species Act of 1973, as amended (ESA). These species are both endemic to Central and South America. Despite conservation efforts, these species' populations are in decline, primarily due to habitat loss, fragmentation, and degradation; small population size; poaching; and regulatory mechanisms that are inadequate to ameliorate these threats throughout their ranges.
