Ten Short-tailed Albatross chicks have been moved by helicopter, from their current stronghold on Torishima Island to the site of a former colony 350 km to the South-east.

Currently, 80-85% of the world population breeds on a highly erodible slope on the outwash plain from the caldera of an active volcano.
