Endangered and Threatened Wildlife and Plants - Two Foreign Macaw Species (US Fish and Wildlife Service Regulation) (FWS) (2018 Edition) The Law Library presents the complete text of the Endangered and Threatened Wildlife and Plants - Two Foreign Macaw Species (US Fish and Wildlife Service Regulation) (FWS) (2018 Edition). Updated as of May 29, 2018 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.
