21 Species Declared Extinct Across Multiple US States

The U.S. Fish and Wildlife Service has delisted 21 species from the Endangered Species Act, declaring them extinct. These species, including birds and mussels, were first listed as endangered in the 1970s and 1980s and have not been seen since. The delisting highlights the need for conservation efforts to protect imperiled species before it's too late. Among the extinct species are the Kauai nukupuu, last seen in 1899, and the tubercled-blossom pearly mussel, last spotted in 1969. The final rule to delist these species will be published in the Federal Register and take effect after 30 days.
