The Nunulu (Bonin Petrel) is a small, nocturnal petrel that breeds in the Northwestern Hawaiian Islands from French Frigate Shoals to Kure. Nunulu historically bred in the main Hawaiian Islands but were extirpated likely due to the introduction of rats, cats, and other non-native mammals. From 2018-2021, Pacific Rim Conservation translocated 249 Nunulu from Midway Atoll to O'ahu, to establish a colony on a high island, protected from sea level rise. In 2021, the first translocated Nunulu returned to O'ahu and successfully fledged chicks! Currently, we have more than 30 nesting Nunulu pairs including a 3rd generation chick.

The 'akihike'ehi'ale (Tristram's Storm-petrel) is threatened by climate change and introduced predators. Most breeding colonies in the Hawaiian Islands are located on low-lying atolls that are at risk of inundation. To help mitigate threats from rising sea levels, Pacific Rim Conservation translocated ?akihike?ehi?ale chicks to establish a breeding population on O?ahu. From 2018-2022, we translocated 110 ?akihike?ehi?ale from K?nemiloha?i (Tern Island) in Papah?naumoku?kea Marine National Monument to O?ahu. We raised the chicks by hand until fledging at James Campbell National Wildlife Refuge in Kahuku. Translocated individuals began returning to the refuge in 2020 and have been breeding there since 2022.
