Endangered and Threatened Wildlife and Plants; Listing the Blue-Throated Macaw; Proposed Rule

We, the U.S. Fish and Wildlife Service (Service), propose to list 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 150 individuals remaining in the wild. Its population continues to decrease despite intense conservation efforts. The primary threat to the species is 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, in addition to diminished availability of suitable habitat. We seek information from the public on the proposed listing for this species.
