Increase in Pairs of the Short-tailed Albatross Diomedea albatrus at an Artificial Breeding Ground

Abstract

In 1993, a new breeding ground for the Short-tailed Albatross Diomedia albatrus was established at Hatsunezaki, on Torishima, Izu Islands, using decoys and sounds. In 1995, the first pair to succeed in nesting and laying an egg there was recorded. Since 2004, the number of breeding pairs increased gradually and a new breeding ground was established. The total number of estimated pairs present at the new breeding ground was strongly correlated with the actual number of pairs that subsequently bred there.
