Three northern rockhopper penguin chicks hatched at a park in Shirahama

Straight Press reported on November 4, 2026, that three northern rockhopper penguin chicks have hatched this season at Adventure World in Shirahama, Wakayama. The park said it confirmed three fertile eggs and that all three hatched: one on October 25 and one on October 27 from pair R003 and R006, and one on October 28 from pair R041 and R045. The October 28 chick is the one that might have been conceived by artificial insemination. The same pair may also have mated naturally, so the park said a DNA paternity test about a month after hatching, expected around December, has to come first. Until that test, a "world first" is a hope the park has stated, not a result.

Keepers are raising the chicks in an incubator for about a week, then returning them to the parents in a closed area. The public display of the incubator chicks started October 30 on the first floor of Penguin Base, from 10 a.m. to 5 p.m., and was described as lasting about a week. A YouTube livestream of a hatching peaked at 19,000 people watching at once. Northern rockhoppers, Eudyptes moseleyi, are listed as endangered by the IUCN. Adults at the park are about 55 to 65 centimetres long. The news is the three hatchings and the public window. It is not a confirmed artificial-insemination success, and the chicks are not on view for the rest of the season once they rejoin the adults.
