After half a century...the bird is back 1999.04.15

The "extinction declaration" was put out once in 1949, and Ahoudori revived miraculously in the Izu Islands and the Bird Island. It was confirmed by Associate Professor Hasegawa of Toho University who has been protecting research since 76 years, and it lays out 213 eggs in Yanzaki in 1998, in addition to 550 birds and 450 young birds, with protection measures from 81 years. 139 chicks were hatching from this, and it was finally on the mark of 1000 birds. It was a rare case in the world where the species that had been declared extinct were resurrected.
