The U.S. Fish and Wildlife Service announced the reclassification of the Aʻeo, or Hawaiian stilt (Himantopus mexicanus knudseni), from endangered to threatened under the Endangered Species Act, a rare and hopeful milestone for a native Hawaiian species. The change, published in the Federal Register alongside a species-specific 4(d) rule, reflects more than 50 years of conservation work that has brought the long-legged waterbird back from the brink. The recovery is documented in a new study led by researchers from the University of Hawaiʻi at Mānoa's College of Tropical Agriculture and Human Resilience (CTAHR) and their partners, published in Ornithological Applications.
