Endangered and Threatened Wildlife and Plants; Listing the Blue-throated Macaw

We, the U.S. Fish and Wildlife Service (Service), are listing the blue-throated macaw (Ara glaucogularis) as endangered under the Endangered Species Act of 1973, as amended (Act). This species is endemic to a small area in Bolivia, and there are estimated to be fewer than 500 individuals remaining in the wild. Its status remains tenuous despite conservation efforts. Threats to the species include: lack of reproductive success (loss of nestlings) due to nest failure, which primarily is caused by competition for nest sites and predation by larger avian species; and the lack of suitable, available habitat in addition to its small population size.
