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
