Eight crested ibises were released into the wild in Hakui, Ishikawa Prefecture, on May 31 [1].

This event marks the first time the nationally protected species has been released on Honshu in 56 years [1]. The initiative aims to promote the birds' settlement on the mainland and support biodiversity conservation, and regional recovery in the Noto area [1], [3].

Crown Prince Akishino and Crown Princess Kiko attended the ceremony to mark the return of the birds to the Japanese mainland [1]. A total of 18 ibises were transported from Sado Island for this project [1]. While eight birds were released during the initial event, the remaining 10 birds are being held in temporary cages [1]. These remaining birds are scheduled for release in early June after a two-week period of acclimatization [1], [2].

To monitor the success of the reintroduction, the birds have been equipped with GPS tracking devices [1]. This data will allow researchers to study the movement and settlement patterns of the species as they adapt to the Honshu environment [1].

Environmental Ministry guidelines typically suggest a release of 15 to 20 birds per session [2]. In this instance, the total group of 18 birds was split into two phases to ensure the health of the animals [1], [2].

Local officials hope the return of the ibises will serve as a symbol of hope for the region. "I hope this provides a push for recovery," a representative said [3].

This effort builds upon the existing population of approximately 500 crested ibises currently residing on Sado Island [4].

“This event marks the first time the nationally protected species has been released on Honshu in 56 years.”

The reintroduction of the crested ibis to Honshu represents a shift from mere species preservation to active ecological restoration. By utilizing GPS tracking and a phased release strategy, conservationists are attempting to establish a sustainable wild population outside of Sado Island. This move not only addresses biodiversity goals but also links environmental recovery with the social revitalization of the Noto region.
