Return to Kīlauea National Wildlife Refuge marks a key milestone in an effort to save endangered seabirds

An historic effort to save the endangered Hawaiian Petrel (Pterodroma sandwichensis), or ʻUaʻu, has reached a critical milestone after years of anxious waiting by project partners: The first of 87 birds translocated as chicks and fledged from the protected haven of Nihoku at Kīlauea Point National Wildlife Refuge has returned after several years at sea. The sighting of this individual, via trail camera footage, is an early sign that this and other young birds that fledged from Nihoku between 2015 and 2019 successfully imprinted on the site and now may start returning to breed, just as conservationists had anticipated. Project partners hope that additional individuals will be lured in by the use of “social attraction” — with the species’ calls played over a sound system — and that they will make use of artificial nest boxes installed within the protective fencing. The ultimate goal is to establish a thriving, new colony safe from predators.

After chicks leave the nest burrow, Hawaiian Petrels and many other seabirds typically spend several years foraging on the high seas as they mature to breeding age, then return to breed at the site where they fledged. This returning Hawaiian Petrel appears to have done just that. It was spotted during an early July review of trail camera footage periodically checked by project partners; the bird’s visit to Nihoku occurred on May 30. The presence of leg bands on the bird confirm a high probability that this is one of the birds translocated to Nihoku four or five years ago.

“We are thrilled to learn of this bird’s return,” said Dr. Lindsay Young, Executive Director of Pacific Rim Conservation. “This is an indication that our efforts in the translocation project to bring chicks to imprint on the site is bearing fruit, providing the right cues that lead birds to this safe haven. The ultimate goal is to establish a thriving breeding colony of Hawaiian Petrels within the fully enclosed fenced area, to protect the breeding birds from invasive predators. This petrel marks the first critical step toward achieving that outcome.”

The Nihoku Ecosystem Restoration Project is a multi-partner effort involving Pacific Rim Conservation (PRC); the Kaua‘i Endangered Seabird Recovery Project (KESRP), a Hawai‘i Department of Land and Natural Resources’ Division of Forestry and Wildlife (DOFAW) project administered by the Pacific Cooperative Studies Unit); the Kīlauea Point National Wildlife Refuge; U.S. Fish and Wildlife Service; and American Bird Conservancy (ABC).

The project is part of a larger, island-wide effort to restore populations of the Hawaiian Petrel and another threatened and culturally important species, Newell’s Shearwater (Puffinus newelli), or ʻAʻo. As was done in this project, translocating birds to protected habitats, from locations where they are vulnerable to threats such as invasive predators, is one important approach that is being implemented to help recover declining populations of Hawaiian seabirds. Other tactics include control of invasive predators, habitat management, fencing, reducing power line collisions, and fostering awareness within the island community on the issue of light attraction’s fatal effects on seabirds. Both petrels and shearwaters can become disoriented by light during their fledging flights and thus are highly vulnerable to collisions.

Dr. André Raine, project leader for the KESRP team, monitors seven nesting areas in Kauaʻi’s remote mountains and says there have been major population declines in the two species, with the Hawaiian Petrel declining by 78 percent and Newell’s Shearwater by 94 percent between 1993 and 2013.

Over the last five years, the KESRP team has located and monitored ʻUʻau and ʻAʻo burrows in the mountains, then transported vulnerable chicks via helicopter to Nihoku just before the critical stage when they become imprinted on the new site to which they will later return to nest. The translocated chicks are fed by Pacific Rim Conservation’s animal care team, which provides feeding, care, and monitoring of the chicks until they fledge from the site and head out to sea.

Since 2015, the team has successfully fledged 87 Hawaiian Petrels and 67 Newell’s Shearwaters from Nihoku. The ultimate proof that the project is successful will be the presence of breeding pairs at the site — a milestone that the project partners are eagerly awaiting.

“After so many years of hard work in the mountains and at Nihoku by everyone in this project, it is hard to put into words exactly how exhilarating it is to see this special bird appear on camera at the site,” said Dr. Raine. “I literally jumped out of my seat and yelled with excitement when I saw the image for the first time, startling everyone around me! Considering all of the threats this species faces on Kauaʻi, their future on the island will only be assured if we use every conservation tool in our arsenal, including creative techniques like the translocation and social attraction project at Nihoku.”

“We are thrilled to reach such a momentous occasion in this ongoing important recovery project,” said Heather Abbey Tonneson, Refuge Manager for the Kaua‘i National Wildlife Refuge Complex. “We look forward to continuing to work closely with our partners on this project to help our endangered seabird populations soar toward recovery.”

“This is a huge step forward, and more confirmation that Hawaiian birds can be saved with effort and creativity,” said ABC President Mike Parr. “It’s been a long wait to see the first petrel return to the protected habitat, but the science said it would. A new nest and chick would be an even bigger cause for celebration. That’s what we hope will be next.”

“The return of the first translocated Hawaiian Petrel to the Nihoku site at Kīlauea Point National Wildlife Refuge is an incredibly important milestone for this partnership,” said Jeff Trandahl, Executive Director and CEO of National Fish and Wildlife Foundation (NFWF), a long-time supporter of this project. “This sighting also provides initial evidence that the protected location is attractive to returning translocated petrels and shearwaters, and hopefully will ultimately result in nesting and the establishment of the first fully protected coastal colony for these species in Hawai‘i.”

ABC and the partners are extremely grateful to the National Fish and Wildlife Foundation for helping to launch the translocation project in 2012, and for supporting the project every year since. We also deeply appreciate the long-term support of this project by the David and Lucile Packard Foundation, Lynn and Stuart White, the Martin Foundation, and Marge Duncan. The Kaua‘i Island Utility Cooperative provided critical support for predator control in collaboration with DOFAW at montane nesting areas within the Hono O Na Pali Natural Area Reserve and the National Tropical Botanical Garden (NTBG) at Upper Limahuli Preserve. NTBG also undertook vegetation restoration at Nihoku, and the Kaua‘i DOFAW Natural Area Reserve team also provided on-the-ground support.

Although the Arctic is best known for frozen tundra, it also has a number of freshwater lakes that are covered in ice most of the year. But the length of time they are ice-covered is decreasing, and this is allowing methane to bubble into the atmosphere.

Globally, lakes are responsible for nearly one-third of biogenic methane emissions, but new research predicts that this level could increase to nearly 60% by the end of the century due to global warming. Methane is a powerful greenhouse gas that traps 32 times more heat than carbon dioxide.

Purdue University professor Qianlai Zhuang and graduate student Mingyang Guo of Purdue’s Department of Earth, Atmospheric, and Planetary Sciences studied Arctic lakes in Finland, where roughly 10% of the country is covered by freshwater lakes.

Their findings in this lake-dense region will help researchers adequately quantify methane emissions from the entire Arctic lakes system. The research was published in a recent issue of the journal Environmental Research Letters.

Organic matter in the bottom of Arctic lakes decomposes, thanks to microbes, and this process produces methane. Enough methane can be bubbled to the surface that it can even be ignited to form 10-foot flames, as University of Fairbanks professor Katey Walter Anthony demonstrated in a 2010 YouTube video.

Zhuang said there are steps that can be taken to slow the increasing emission rate.

“Based on our study, the increase of lake methane emission is mainly due to the warming climate and reduction of ice-on days,” he said. “By reducing anthropogenic greenhouse gas emissions and mitigating the climate warming, the Arctic lakes will have longer ice-on days and lower methane production rate, thus slowing down lake methane emissions.

“Also, reducing organic matter flow to lakes in some ways would mitigate the emissions by reducing the microbial activities, leading to lower methane emissions.”

According to Guo, analysis was conducted using a lake biogeochemistry model developed in the team’s laboratory at Purdue.

“The study took advantage of a relatively large observation dataset collected by Finnish scientists,” he said.

This research was supported by NASA and the U.S. Geological Survey.
