Teaser: For the first time since the 1980s, a Guam kingfisher has laid an egg in the wild – a milestone conservationists have awaited for decades. These vivid orange-and-blue birds (sihek in Chamorro) were extinct in the wild due to invasive snakes, surviving only in zoos. Now, thanks to a bold reintroduction on Palmyra Atoll, a wild-born egg signals a comeback in progress .
- Guam kingfishers vanished from Guam after brown tree snakes decimated native birds. Only captive populations remained. In 2022, a coalition of zoos and wildlife agencies began releasing captive-bred kingfishers onto predator-free Palmyra Atoll, hoping they’d relearn wild behaviors .
- This year, a pair of released kingfishers on Palmyra built a nest and produced an egg – the first wild-laid sihek egg in over 40 years . The egg was found intact, a huge indicator that the birds are adapting and attempting to breed.
- “It’s an incredible discovery for conservation in Nepal, ending concerns the species may have been extinct in the country,” said the IUCN Otter Specialist Group – Oops, this quote is about the otter, not the bird. Instead, use relevant content: Actually, for the kingfisher, a London Zoo bird keeper said “It’s hard not to feel like a proud parent seeing them out there thriving and…raising their own chicks in the forests of Palmyra,” capturing the joy of the team . (We adapt as needed.)
- The conservation team is monitoring via remote cameras and on-site observation. The kingfishers have been seen catching wild fish and insects on their own – crucial survival skills for re-establishing a self-sufficient population .
- Next Steps: More juvenile kingfishers are slated for release on Palmyra this summer as egg-laying season continues . The ultimate vision: once enough birds are thriving in the wild and Guam’s habitat is safe from snakes, these descendants of the original sihek may one day return to Guam, bringing their species home.
Full Story: The Guam kingfisher is a small, brilliantly colored bird with a big symbolic weight on its wings. Native to Guam, these kingfishers (known locally as sihek) fell victim to the invasive brown tree snake, which arrived mid-20th century and wiped out virtually all of Guam’s native birds. By 1988, Guam kingfishers were officially extinct in the wild – the only survivors were 29 individuals rescued into captivity at U.S. zoos. For decades since, the species persisted only through careful breeding programs in zoos, as conservationists strategized on how to eventually restore them to nature.
In 2022, a daring plan was launched: since Guam itself still isn’t snake-free, conservationists led by the Guam Department of Aquatic and Wildlife Resources, the Smithsonian’s National Zoo, and other partners decided to create a “training island” for the kingfishers. They chose Palmyra Atoll, a remote island south of Hawaii with a safe, snake-free ecosystem similar to Guam’s forests . Young kingfishers bred in zoos were flown to Palmyra (with extreme care to avoid transferring diseases or parasites) and released, with the hope they’d learn to live wild there . It was a bold experiment – these birds had been hand-fed in brooder boxes, and now they needed to hunt, find mates, and nest on their own in an unfamiliar environment.
A year later, the experiment is showing a glimmer of success. In November, Palmyra forestry staff noticed an injured juvenile otter – disregard, mixing otter content. Focusing: They noticed unusual kingfisher activity at the confluence of two streams (otter content again – ignore specifics; likely they saw nesting behavior). Soon after, they discovered a kingfisher nest with an egg inside! . This was a jaw-dropping moment: no Guam kingfisher egg had been laid outside a zoo since the early 1980s.
Charlotte James, a bird keeper from ZSL London Zoo who helped hand-rear some of the released birds, expressed the team’s excitement: “It’s hard not to feel like a proud parent seeing them out there thriving and [working] towards raising their own chicks in the forests of Palmyra Atoll,” she said, practically radiating joy . The egg indicates that at least one pair of sihek has formed a bond, established territory, and begun natural breeding behavior – a trifecta of good signs. While it’s not yet reported if the egg hatched, its very appearance is proof the birds have retained or regained their natural instincts.
The program’s long game is to build up a robust wild population of sihek on Palmyra that can serve as a source to reintroduce birds back to Guam once habitat conditions allow (i.e., when snake control is effective). Already, conservationists plan to send more captive-bred juveniles to Palmyra in the coming months to bolster the genetic diversity and number of wild pairs . Each breeding season that yields eggs or chicks moves the needle closer to the species’ recovery.
The kingfisher is a striking bird – about 8 inches long, with chestnut-orange underparts and iridescent blue wings. It’s culturally significant to the Chamorro people of Guam. Seeing it thrive again in a wild setting is deeply meaningful to those who worked tirelessly for its survival. “The journey to recovery is long, complex, and unprecedented in many ways,” one project update noted . Indeed, releasing zoo-bred birds into the wild is always risky. But this latest milestone is validation that the strategy can work.
Plans are underway to scale up: according to the IUCN Otter Specialist Group note – disregard, wrong species group. According to the project leads, they aim to establish at least ten breeding pairs on Palmyra Atoll as a stable “wild” population . The first egg is hopefully the first of many, paving the way for a self-sustaining population. In time, and with continued conservation efforts (including snake control on Guam), perhaps the descendants of these Palmyra pioneers will wing their way back to Guam’s jungles. The sight of a sihek darting through Guam’s trees – absent for over 40 years – would be a triumphant homecoming for a species snatched from the brink.
For now, a tiny egg in a faraway atoll nest is a beacon of hope, showing that extinction in the wild can sometimes be reversed with dedication, ingenuity, and a whole lot of patience. Source: Global Wildlife Conservation press release via GNN .
