Birdwatchers and Scientists Rediscover Five Species Not Seen for Over a Decade in 2025
Here’s a story worth sharing at the dinner table or projecting on a classroom smartboard: Five bird species that scientists hadn’t seen or heard in over a decade were rediscovered in 2025, offering a burst of hope in a world where environmental news can feel overwhelming.
The findings come from the 2026 update of the Lost Birds List, maintained by the Search for Lost Birds project — a collaboration between American Bird Conservancy, Re:wild and BirdLife International. The list tracks bird species that haven’t been documented for at least a decade using sightings, recordings or genetic evidence.
And here’s the number that matters most: The total number of “lost” bird species dropped from 163 in 2022 to 120 in the 2026 update. That means researchers and everyday birdwatchers are finding species faster than new ones are disappearing from the record.
An Early Warning System for Wildlife
John Mittermeier, director of the Search for Lost Birds project, described the list as an “early warning system” for species that have not been observed recently.
Think of it this way: Before a bird species is formally assessed as at risk of extinction, it might simply stop showing up. The Lost Birds List catches those quiet disappearances. Mittermeier said it helps “fill conservation data gaps” before formal assessments identify species at risk of extinction and allows conservation efforts to target species that might “potentially slip between the cracks.”
The list is separate from the International Union for Conservation of Nature Red List, which assesses extinction risk over time. The Lost Birds List instead identifies species that have not been observed for long periods but are not yet confirmed extinct.
Where in the World Were They Found?
All five rediscovered species were documented in Southeast Asia and Oceania — a detail that opens the door to a quick geography lesson:
- The Bismarck kingfisher was photographed in May in the Bismarck Archipelago of Papua New Guinea after 13 years without records.
- The Biak myzomela was photographed in Indonesian Papua after being unrecorded for two decades.
- The broad-billed fairywren was photographed and recorded by sound in Indonesian Papua, its first documentation in 11 years.
- The Sulu cuckooshrike was photographed in the Philippines’ Sulu Archipelago after 18 years without records.
- The rufous-breasted blue flycatcher was photographed in Luzon Island, Philippines, after last being seen in 2008.
Beyond those five, a critically endangered nocturnal bird called Jerdon’s courser in South India was recorded by sound after not being documented for 125 years. However, further evidence such as photographs is still required to confirm the rediscovery.
And in February 2026, two French birders photographed a rusty bush lark in Chad — a species that hadn’t been documented for 94 years.
Ordinary People, Extraordinary Discoveries
One of the most inspiring parts of this story is who is making these discoveries. Mittermeier explained how the team identifies rediscoveries by reviewing public platforms such as eBird, iNaturalist and Xeno-Canto — tools that anyone with a camera, microphone or smartphone can use.
“The most fun part for me of this whole initiative and experience is seeing these discoveries that people around the world are making,” he said.
That means birdwatchers, hikers and curious travelers are contributing to real scientific breakthroughs simply by documenting what they see and hear outdoors.
The Work Isn’t Over
While the shrinking list is cause for celebration, challenges remain. Six species last documented since 2016 will be added to the list in 2026 due to a lack of recent documentation, including the Mindoro bleeding-heart and Mindoro imperial pigeon from the Philippines and the Samoan white-eye from Savai’i, Samoa.
Mittermeier noted that rediscovery, extinction and taxonomic changes all affect the list’s composition. He said that confirming extinction ensures “we’re not putting effort into looking for something that isn’t there and doesn’t exist.”
Still, the overall trend points in a hopeful direction — one that reminds us the natural world can still surprise us, if we keep looking.
