Endangered and Threatened Wildlife and Plants; Proposed Rule To List the Short-Tailed Albatross as Endangered in the United States

Résumé

Originally numbering in the millions, the worldwide population of breeding age birds is currently approximately 500 individuals and the worldwide total population is less than 1000 individuals. There are no breeding populations of short-tailed albatrosses in the U.S., but several individuals have been regularly observed during the breeding season on Midway Atoll in the Northwestern Hawaiian Islands. Current threats to the species include destruction of habitat by volcanic eruption or mud or land slides caused by monsoon rains, and demographic or genetic vulnera
