Five “missing” bird species — not seen, heard or documented in the wild for a decade or more — were “found” in 2025, according to the 2026 annual update to the Lost Birds List. It’s a tally of species that haven’t been photographed, recorded or their genetic footprint detected for more than a decade. Another extraordinary rediscovery came earlier this year: A bird “missing” for 94 years was documented in Chad. With the new changes, the overall number of “lost” birds, as defined in a 2022 study, dropped to 120 from the 163 listed when the list was first published in 2022. The list is maintained by the Search for Lost Birds project, a global partnership between the NGOs American Bird Conservancy, Re:wild and BirdLife International. Six species considered lost since 2016 will be added to the list in 2026. Unlike the IUCN Red List, which tracks the extinction risk of species over time through extensive periodic assessments, the “lost species” list flags those that haven’t been documented in a long time — the first signs of trouble before they vanish forever. John Mittermeier, director of the Search for Lost Birds project, called the list an “early warning system” for birds not seen in a while. He said it helps “fill conservation data gaps” before rigorous assessments catch up and spur action to protect species that might “potentially slip between the cracks.” Every year, Mittermeier and his team scour through public birding platforms, such as eBird, iNaturalist, Xeno-Canto and others,…This article was originally published on Mongabay
