We, the U.S. Fish and Wildlife Service (Service), determine the northern subspecies of scarlet macaw (Ara macao cyanoptera) is an endangered species under the Endangered Species Act of 1973 (Act), as amended; the northern distinct population segment (DPS) of the southern subspecies of scarlet macaw (A. m. macao) is a threatened species under the Act, and the southern DPS of the southern subspecies of scarlet macaw (A. m. macao) and subspecies crosses (A. m. cyanoptera and A. m. macao) to be threatened species based on similarity of appearance. We are also establishing a rule pursuant to section 4(d) of the Act for the A. m. macao subspecies and subspecies crosses to provide for its further conservation.
