Endangered and Threatened Wildlife and Plants; Threatened Species Status for Emperor Penguin With Section 4(d) Rule

We, the U.S. Fish and Wildlife Service (Service), determine threatened species status under the Endangered Species Act of 1973 (Act), as amended, for the emperor penguin (Aptenodytes forsteri), a flightless bird species from Antarctica. This rule adds the species to the List of Endangered and Threatened Wildlife. We also finalize a rule issued under the authority of section 4(d) of the Act that provides measures that are necessary and advisable to provide for the conservation of this species.
