The U.S. Fish and Wildlife Service has finalized protections for the emperor penguin, a flightless seabird endemic to Antarctica, under the Endangered Species Act. The emperor penguin is listed as a threatened species and includes a section 4(d) rule that tailors protections for the species. The impact of climate change on sea-ice habitat, where the species spends the majority of its life, is the primary threat to the penguin.
